  • I like the kid (speaker's granddaughter's) name: Mithra = Loving-Kindness

  • I've seen brain 'exercise' help an brain injured relative recover to the point at the age of 53 he returned to college and received top grades in his chemistry and biology classes. Incredible when I consider he lost full coordination and speech for long period of time. The work such neuroscientists as Dr. Merzenich achieve definitely made a difference. One critique: less technical explanation for the general public..

  • how do you rewire the brain for better spelling on powerpoint presentations?

  • This science is sooooooooooooo goooooooooooooooood to listen to

  • An old professor/Doctor is talking , be polite or shut up and leave. If you reached (ever in your jealous and unhappy life) this level after years of research then come and talk but not here. No, on your own session(If anybody would ever allow you to even have a session).

  • This was a brilliant speech. Well done!!!

  • youtube.com/watch?v=vIpnkqEDaU­A&feature=related

  • Strong minded people are responsible for the lives of the weak minded people. I take advantage of those who are weaker minded and give help to them to lift up their surviveblity as far as I can for that, and I do that free of charge, unlike this guy which he is getting paid for it. He thinks he is protected from those who he takes advantage of. Wisdom is not one of his strength. We all deserve the same amounts of goods. Who has the right to say someone else has free will yet takes from them.

  • guys: are you saying you'd not be nervous giving a TED talk?

  • The sign of intelligence is to learn from others rather than to insult smart individuals who are courageous enough to dedicate their lives to learning. Their generosity to share their knowledge is commendable. Please share your knowledge in greater detail so we can benefit from it.

  • I would like to know any empirical data that supports the lofty notions presented in this talk.

  • @ilovemingers

    You did not notice how the guy has neuroscientist next to his name.

    Just do a google search of his name.

  • The first 2:00 mins I want to cry... it seems like he's nervous and sad the whole time...

  • Oh! ...and as for the negative cracks on Dr Merz, of your brains were more plastic and

    fluid within your ability to hone, u'd be able to not fixate on the negatives while emiiting positivity in suggestions or acknowledged appreciation of the obvious feat accomplished in simply remembering the data let alone presenting it in a cohesive contiguous fashion. How Capitol!

  • "The Brain That Changes Itself" Yes wonderful exposition on neurogenesis and our very malleable neuroplastic environment...stories of triumph and willed miracles leave you anxious to participate in this collaborative brain renaisance.

  • Poor teaching skills. He needs to be able to translate his language in a language non-academics use.

  • @leoca if you can't understand him: you are stupid

  • @wamuq He can't understand himself.

    

  • @leoca :) let's just be friends and let it be. ^^

  • thanks for posting this up. Just been reading  about plasticity of the brain and found it fascinating. This man was mentioned. Appreciated. :-)

  • @prinia

    Did you read The Brain the Changes Itself? I think you did haha Great book! I'm excited about changing my brain.

  • You must have problems with you higher thought process.....When I hear him speak, I hear an intelligent mind giving an informative lecture..Your brain picks up on the details that don't matter, leading me to believe that you are an idiot.

  • suck my balls.

  • Just as I expected a fucken Idiot

  • Oh please, how ridiculous can you be. I made an innocuous comment about how the guy isn't that great of a public speaker. You have no reason for any assumption on my opinions otherwise.

    "...details that don't matter"

    Well I happen to think that my observation does matter, given this mans work. It's curious to me why a man who charges so much money on purportedly miraculous brain fitness program, has not been able to train himself to become a better public speaker. It's just a bit ironic...

  • Before you call someone an idiot I suggest you have proper reasoning for it. Don't base insult on a one sentence comment given in a context you don't even understand.

  • Idiot.

  • All detail matters. See: (Autism) Autistic Savants

  • Wich is btter : false teeth or no teeth.

    If you loose a limb and did'n magage to recover your own limb to be reatached, what is prefferable : to have a choice between a robotik limb or human from a freshly died donor, or to have no choice. Mechanical heart, inner ear implant : those definetly prevents you from haveing sex or feeling stuff.

  • So you declare that transhumanism will be the end of emotions and sex, wich means that the genitals or the hipotalamus will be removed. Then you define transhumanism as any artificial implant, and yet say that you have never said anything about rapaceing the hipotalamu or the genitals.

    What I am talking is solving medical problems with the halp of artificial body parts whan that is apropriet, or when that is the preference of the patient.

  • I'm sure single celled organisms wouldn't find you very sexy.

  • To set the record strait. I made the following points:

    -No method should be discarded, All options should be on the table.

    And you made the following points :

    -Sex is great.

    -Smart kids + iternet = armagedon(assuming that someone is proposing that the hole brain should be replaced with computer at childbirth)

    Fell free to corect me.

  • Yes, those are only some of which, of course. as to sex - Sex is great, and transhumanism will discard that, or we won't properly mimic it, the same way in which a sex toy can't mimic it.

    -Dumb kids + piratebay into brain = armagedon, as i've said, these people will be givin astronomical abilities on one hand, yet on the other they don't understand any life values, ie a child waging nuclear/biological warfare against his mother for not buying him an xbox

  • Why the hell would healty kids need brain implants, and whats the diferenc if they had the piratbay in their head or in their computer?

    They will stil use the internet for what they use it today.

    "these people will be givin astronomical abilities"

    Here we are in Disney world again. This is baseless assertion, and is not self evident as you probably think. You just oversimlify things.

  • #1: exactly, but because it means school in a day, people would go in for it. #2 on pirate bay, it's only the same as a library or such, while if it was in their brain they actually understand what is going on and obtain the qualification and UNDERSTANDING in a very short while, probably a few minutes. They may understand one thing, but the rest won't be there, and also seeing that their brains are undeveloped, it's any1s guess as to what they may do with such knowledge. or imgie osama with this

  • "if it was in their brain they actually understand what is going on and obtain the qualification and UNDERSTANDING in a very short while"

    No they won't. The brainc will still process information in the same manner it does today. The manner of processin the information may be thought by such means as what mister Merzenich is talking in this video, and not by phisical manipulation. the brain still desited wich part of information is defined by assotiation with wich other part previously learned

  • Comment removed

  • the culturally and religiously obsessed, unfortunately stand in our way, which is why i think that a simple ethical eugenics and planed parenting program will sort that part out.

  • Eugenics is a pseudoscience. Genetic diversety makes species better able to addapt. The "pure race" put forward by egenics is genetic self-mutilation. Meems can be griven extinct by meem selection(education) not by geen selection.

  • how on earth can eugenics be a pseudoscience? it is a social philosophy, which encourages that people should be -well-born'(gk.) it doesn't say what 'well' is or how it should be done.

    what hitler done, he himself did not call eugenics, and there was no science behind it, however the jews have made huge progress and they are even widly practicing eugenics on their own today. google jewish victor center

  • Well may be I'm wrong about eugenics, but that's irrelevant to the point. However what you are talking here is improveing the works of "mother nature", so what happened with the natural being superbly desined? If our brains are "intelligent and as developed enough" then why you need eugenics?

  • nah, i said that there are people who have brains developed enough, not everyone. i said that we should increase IQ by at least 20 to 30 points above the current level of 86, say to at least 120to130. Mother Nature is not at play, and if she was it would be far to cruel to imagine. however i don't think that we understand nature too, perhaps eugenics should simply fall part of ethics. aren't charities and food aid programs in nature, and no dole either. We need ethics and we need progression too

  • I would agree with you on that, exept that I say that there is no such thing as enough developped brain. development must not be limitted in any way.

  • 'never'? u sure? and do we really understan what sentience is and how everything relates and functions with it? These are DEEEP philosophical questions, and i don't think that humans would properly understand how to quantify this. remember that the brain is roughly equavalent to 100bn G5's, and even so those G5's don't emulate everything. I say that we are FAR from where we should be, but that there is also a limit to what is ultimate to us.

  • this way, to be forward, and i hope that people will won't be immature while reading this: say you lived in a world where the avr income was $200k, people own 5 phds, where all illnesses are simply cured by brain transplants, where those braintransplants provide a diying 80yo patient with the body of an 18yo 15" penis porn star, where ageing is left, where you own penthouses on many diffrent planets, where you work for 10 years, party for 100, then repet the cycle again, is this not enough?

  • I would say that this is a nice science fiction. What you are proposing is in my oppinion(I've not make real research on this) much more complicated and expensive than artificial rewireing of damaged nerve connections.

    My whole point was that arguing wich method of immortality is better, while we don't have any such method, is as sily as arguing wich alien civilisation, that we know of, is the strongest.

  • Brain-transplants? 'Already have all it takes, all we now is re-connect the spine and 12 nerves on either side of the brain. Tissue rejection is not an issue at all. Hands have been transplanted, even faces, nerve transplants work, ' those even those transplanted hands can feel and move as if nothing happened in the first place. i've mentioned earlier, Harvard med and some others say that in less than 10 years we will make these nerve cells to perfection, to our luck first and for most the spine

  • Perhaps a printer such as the one which has recently been made to print heart tissue, in such

    precision that the tissue actually spontaneously began beating when fed, these

    people claim that they would be able to print entire whole organs from

    scratch in the near future. If we could simply take these harvested cells, printer and have the computer MRI a tiny cross section of the clone and the hosts body, we could program a simple program to print frames to form a 1mm section to connect the two.

  • brain is adaptive to reconnect to new nerves, it works almost like USB. the brain and each nerve is NOT at all hard wired to the brain, only sections are, and even so the brain has shown much plasticity so it is adaptable. sections are far large enough to easily connect, just that we want it to work the very next day.

    speculative, but that's one way at least. patient can go home from bring a sickly 80yo the previous day, to being a staggeringly rich and educated 18yo porn star the next.

  • "patient can go home from bring a sickly 80yo the previous day, to being a staggeringly rich and educated 18yo porn star the next. "

    Yea keep talking shet man, You need to be stagerengly rich to beging with to affordsuch thing in the first place. I gess that excudes 98% of humanity, so I prefer to placre my hopes in something that can actualy benefit me.

  • No, think of howmuch it costs to raise a child, university and all, something like 250,000 pounds, not including lost time and what else, think of how short that education is being used and how the rest is only slowly falling apart. this is utmost inefficient. if the person was allowed to live another life they may yet become super experts at what they do, and the more developed the more money. when a person dies it's like a libary burns, i am here to save it

  • Yea, and there will be equality and peace and love and free drugs and no problems with overpopulation, exostoin of the natural resorces, wars, crimes ... Exept that we are not liveing in a Disney world. I can't see how can this thing be affordable in the first place exept if you kill poor people to take their bodyes for hosts of the rich people's brains. We can't yet create entire human body in a lab, and if we learn how to do it, I'm shure that it won't be affordable for the common people.

  • Thechnology in the other hand is geting ever cheaper and affordable for everybody, so discarding it as a method of prolonging life just on the basis of prdjudices abouth ntural vs artificial, is not a wise position.

  • More educated & creative, the less of a concern overpopulation will bring, infact a higher population may actually be better seeing that there would be so much more development and cooperation. Affordable certainly, maybe not to everyone at first, but what people would pay is priceless, people would pay anything, and even if it is the entire 401k, it would be well worth it, and they would easily be able to make it up again faster this time. certainly won't be 401k, it would be only one procedure

  • poverty still exists yes, and many would not be able to afford this, but even so, does that have a say that we should not make it available in the first place? Should we make space travel free so that Somalians could space travel too? No, and yes this will bring more development and thus much more wealth to the world, wealth creates opportunity for them to lift themselves out, thereby decreasing poverty. Imagine that we didnt make computers, just because some can't afford it

  • Compare Japan, HK, Iceland(completely self-sustaining) and Macau to say India or Ethiopia. The Japanese have no resources, but yet they are a throbbing empire - this is because of the skill of their workers is so high.

    This planet could take plenty more, just matters who, and even so, there are other planets in the not-so-distant future to explore and mine too, Mars and Venus for example. But for now that would not be necessary. as to overpopulation all we need is a china-like one-child policy

  • And Japan is also the most hi-tech nation, and the japanise have no predjudiceses abouth useing technology to improve every aspect of their lifes.

  • And that would apply to brain-transplants too. An no, nano-tech implants is not done in japan. It is a ethical issue, just as nuke tech is. look, i am not a dildo robot, i am the result of 3 billion years of intense research. nothing could better that, unless only really small mods to improve lifespan as mother nature did not serve individual sentience as a variable, although it is the utmost real and important one to us .

  • "It is a ethical issue"

    O raly? Would you mind explaneing why?

    Or are you just gona assert it as you have been doing so far?

  • I have yes much earlier already. as with the example of the 6-yo with knowleadge of advanced vvriology too.

    Ethics aside, i don't think that everyone would want to go into this, it would be like 'the Borg' in startrek, and it could also be very unfair to those who don't want to take part. please scan back at my comments and comment on the realavant ones, i am repeating here.

  • Great, you naw bring back to life the other rediculous strawman argument.

    Well, I'm done with you.

  • If it's a strawman, then at least you should say why it is so, or your the only strawman yourself by saying things which have nothing to stand on. ad-hominem is also no argument

  • Why it's a strawman??

    I have already answered that. It is completely irrelevant. How does an artificial arm for example, make you super vilan wanting to destry the world with biological weapons?

    Or how does it prevent's you frome haveing sex or expiriencing other emotions? You are makeing basless assertions, unrelated with the poin that I am makeing, and you are arguing agains them, not against my arguments. That's what strawmaning means. Comprende?

  • Fleshlight or real vagina? Dildo or real penis? which do you prefer?

    Sex is most of life, besides for our moral obligations to others, sex is what we live for, and what comes from saving the lives of others, sex for them too. we live for sex. good sex is crucial, and i can't imagine a robot ever providing the ultimate beauty of natural sex. as to other nano-implants, i don't think that this either will produce what is real and what we love. exception to a few temporary, such as med bots...

  • the japas aren't replacing sex with artificial objects.

  • Did you have no argument in your favor, so that you have to turn back to those ridiculous srtawman?

    I ask you againg, what made you think that I am in favor of removeing of the hipotalamus , or the genitals?

  • disconnect? what are you saying? i was speaking of brain-transplants as a method of turning beck time in an instant.. comprehending now?

  • Ofcourse I know what you are sayng. You have not stopped ranting the same stuff again and again. And you hgave not answered my question.

    "disconnect?" ?? Well I don't get where that came from.

  • No, i didn't say that, i said that you should reply to those posts instead of brining up the same thing again, Im not going to re-argue things from the start all the time, continue or critisize on where i left off, don't just start all over again, or your wasing my time

  • You didm't said it directly. You implyed it. Since sex is performed with the genitals, and since emotions are result of the neurotrnsmiter produced in the hipotalamus, claiming that changeing any bodypart with artificial one will make sex, or emotions imposible, implies that the genitals or the hipotalamus will became dissfuncional.

  • "poverty still exists yes, and many would not be able to afford this, but even so, does that have a say that we should not make it available in the first place? "

    I am not the one who is arguing that we mustst discard one particular way of prolonging life. So let's put it this way:

    Poverty still exist and will exist for quite some time, so let's not discard any other methods that may be much more affordable. How abouth that?

  • The more educated as a percentage, the more able we are to solve these problems. The world is not suffering from overpopulation just in it self, the world is suffering and at even more future risk, of the overpopulation of people who can't sustain it, the uneducated and the uncreative. This will bring correction to that balance by bringing and prolonging the problem solvers to inevitably help everyone. Earth could take tens of times more people the only problem is how, and this is the answer.

  • yes it may be costly, but nothing in comparison to what other illnesses cost, and a very very tiny fraction of what it costs to raise a child. It will BRING wealth to this world.

  • They may be deep questions, but they are allso irrelevant to our disscusion. And stating that there is ultimate limit is empty assumption.

  • In truth could you really say that ^? No, they are realavant, this is transhumanism here, and those will be some of the implications. One can't deny that those will be the consequences, and how may be the question here, but it is still a serious concern. No, i think that we should remain fixed in our biological state, and to achive all other immortality and forever youth, we could do this through bio-tech and not permanent non-biological implantations.

  • Here is where the problem is. You just keep arguing against claims that I have not made. In wich of my comments hav I said anything abouth transhumanism, or permenent. How does "we must not disvcard any options" became in your ears "we should dispose of anything biological"?

    I don't even belive that transhumanism is possible. You can't replace the brain with computer, because that means to kill the person, not to make him immortal.

  • and this is what i thinkk will slowly happen, remember that we still do not even understand sentience works or even how everything falls part of it. psychology is still in the stone ages. as to children with serious disabilities, i hope that tempory implants or technology could someday correct whatis wrong until we find a more functional and natural solution, ie what harvard is doing to produce own braincells in lab. btw transhumanism is certainly possible, in fact it IS ALREADY HERE

  • "i hope that tempory implants or technology could someday correct whatis wrong until we find a more functional and natural solution"

    That was exactly what my whole point was about.

    Noone is going to force you to became robocop, but if there is problem that can be solved with implant, and you can't afford a biological one, you'll be hapy to have a cheaper alternative.

  • Besides for our obvious obligations to thics, what matters in life would be GREAT SEX, YOUTH, HEALTH AND WEALTH. the aurora is beautiful enough, the physical and those which matters above, could much simpler be provided by much simpler means, such as brain-transplant into identically naturally artificially grown bodies, or perhaps reprogramming a small section of our DNA to stop and perhaps reverse ageing, there are many medical breakthroughs on the horizon.

  • The emotions that we feel can be produced by way much simpler means - neuro-hormons, because that's what they are in the firs place. Our notion of butuy is subjective judgement. I don't why are you stateing that the human brain will loose those feeling if you encahnce it.

  • no, you will never be able to accuratly and effectively create a beautiful day of love and steamy sweaty sex that even words cannot explain. far too complex if not impossible, id say that even teleportation would come first

  • What's that suppose to mean? What are you arguing against?

  • He sounds out of breath.

    Other than that, a great lecture!

  • he doesn't pause once. not even to breath... at least after ten minutes in.

  • I think he's just really nervous.

  • were not the only creatures on this planet that can ask why dumbass. your really stupid. thats insects that cant ask why and its because they run on pure instinct. any animal or human can wonder why its here. you are very stupid

  • what the hell are you so mad about? just because your life sucks doesn't give you the right to call me, a person you really know nothing about, a dumbass. i have an IQ of 131. not the smartest person in the world but above average.

  • if we've got a billion firefox doads and firefox a 5000 code program doesn't even work, how are we going to trust a man made program that requires more than 100 billion g5's

  • you weren't designed, your are a product of survival. technology is natural, because WE create it. just like a monkey using a twig to retrieve grub worms, we will use computers to preserve our thoughts and consciousness. if what we create happens to hinder our survival, we discontinue it, hence, evolution. what you are talking about is NOT taking control of your own evolution. natural selection has a solution for creatures who stay inept and let "nature" run it's course. it's called extinction.

  • Natural = good because it is far more well developed, mother nature is the ultimate designer, We learn from nature, architecture everything, we an't really quantify things in depth as she can, neither have we had trillions of species and experiments, research done over billions of years. we are meerly even in the baby stages of understanding this 14billion yo lady. we've meerly created the robot vacume cleaner, which even in itself is far less complex than even bacteria.

  • Even my penis is far more beautifully designerd than any machine ever, it blows peoples minds, how it's curved, the sleek gliding action, the well tuned sensation, even the smell, i won't ever swop for a dildo. Human beings can only replicate exactly what mother nature has done, onoly to their own advantage, but it would be bad to change mother nature. which is why i reccoment brain transplants, and as i've said, firefox(100million downloaded) is even faulty, im not going to trust software,

  • and firefox works just fine if you continue to update it.

  • hmm it could be possilbe to create identical brains when using virtual reality replacement tehcnology from birth. runnign the same program would theoretically cause the same brain activity as long as all relevant inputs are controlled.

  • don't need a virtual clone, and considering how near infinatly complex our brains and the self (sentience) is, i don't think what you propose may be possible for at least the next few millennia. brains can rejuvenate, they are slow yes, but when you provide a fresh body(probably a clone or artificially grown person(don't worry, sci-fi, but it's very doable)), it would drastically slowdown damage, providing the opportunity for the brain to clean up messes and rplace cells with fresh young 1s

  • his speaking pattern makes me nervous.

  • true dat

  • This is incredibly powerful knowledge

  • if you studied for 30 years of your life to earn that phd, when ur asshole neighbor just implanted 3 into his brain. with this weird metal part haning out of his skull all the time.. yes he wuld earn much more than me, but does he deserve it, and would it be the best for all, talent and poetry can't be learnt.

    then he wants a prosthetic hand, leg, and everything, does that turn you on?

    why not replace his old hand with a brand new ORGANIC one from some harvested head-less(been done) clone?

  • "with this weird metal part haning out of his skull all the time"

    That's hardly necessary. We've had portable wireless communication devices for a while.

    "but does he deserve it"

    If he's using those 3phds to make a significant contribution to improving the overall well-being of humanity, the answer is: hell yeah!

    If rewards were given based on effort rather than results, we'd have some serious problems.

    I have one concern: such developments might make us more vulnerable to social breakdowns.

  • Extreme social breakdowns, your basically giving every second human being a nuclear bomb.

    imagine 8-yos downloading high-level virology, or advanced nuclear physics onto their brainlink

    thrier are far better ways to find the ultimatum in humanity, trans-humanism should not be one of them

  • ...Piratebay

    what's next? the government needs to regulate it, and what is the one and only way to o this? to montor everyones thoughts through some server, and we need an off or sleep switch for everyones brains, 2 elections later a fascist dictator steps in, humanity a a hole are controlled as a herd of sheep, working only for one guy. No conspiray theories, this is athe most likely possility if this tech gets used for non-biological 'enhancement

  • "what is the one and only way to o this? to montor everyones thoughts through some server,"

    Do you really believe this? I'm always curious when I hear people say things like this.

  • WHY NOT? wifi remember... and have you read the rest?

    don't like conspiracy theories either, but would this really be a conspiracy seeing that this video says that it's doable?

  • "seeing that this video says that it's doable? "

    He's talking about brain plasticity not actually 're-wiring' the brain. You can't hook up wifi to a brain. You should try though, make a video, and post it on Youtube.

  • im not the one who suggested wifi, but wi not?

    plasticity, well 'chips love brain-cells', braincells in themselves are pretty impressive machines, they could wrap around these chips, these chips may make it possible to do these things, i see no reason why not, have heard many other ivy celebs say the same

  • Well.... government regulation really wouldn't work.

    Even if we wanted it, and there were no political risk, you can't stop people from building the chips without safeguards once they're out there.

    It might be possible to monitor the phenomenon locally by monitoring every single form of communication and regular medical checks.

    But somewhere in the world it'll be out of control.

    Another interesting possibility: growing and conditioning brains as bio-computer to solve hard heuristic problems.

  • government reg (THX 1138) or not, this will surely create a rat race species, and by giving 8yo's access to how to build your own nuclear weapons, is not the child hood i ever dreamt of

  • IT is developing at an astronomical rate, and it will only continue to develop, in a few years we will have bluetooth headsets with rollout HD oled screens, terrabyte microSD cards, and be able to remote desktop our pc's at home. we could already do voice search anywhere with MS's new 'tellme' service, GPS find friends anywhere, everyone has millions of libaries fitted right in their pocket, probs a cam to record ur life, LTE, biosensing, dna syncing eugenics.... all in a BT headset.

  • this should be enough, we don't need trans humanism, this tech should only pose as a temp solution to illnesses, until a more nature restoring one is found.

  • It'll be a long time before you get DNA manipulation tools in a BT headset.

    You're right about everything else.

    We're not at trans-human times yet, but hopefully by the time we get there someone will figure out the details of cyborg parenting.

    The hypothetical 8-year olds actually do freak me out a little. Everyone knows that kids are generally crazy, and at times deeply evil.

  • No, Berkley has already got a static dnaa nd molocule reader, round the corner.

    we will never figur out how to sensor anything, especially not from children, not 1 house in america where teens odn't have access to porn.

    We don't need this, why do you want it? I want to be immortal and live in ayounger body of myself or even a well endowed porn star perhaps. simply need brain transplants, cure to all diseases, ageing, even susan boyle, everything, we don't need techno enhancements.

  • "manipulation", no, they would be able to synthesize it, not change it, another thing i stand against. ,selection is great, i think actually necessary, however manipulation is another card in a packed stack of 1 bn cards, 1 of which you wouldn't simply change. but then again, brain transplant will still be much much more doable than the public thinks, i think that this would be our ultimate solution to everything, brain also minimum t no tissue rejection, and it adapts and rejuves..

    [/end nerd]

  • The brain doesn't rejuve very well. Neurodegenerative diseases become very common with old age.

    You won't achieve immortality with brain transplants unless we find a way to boost tissue regeneration and DNA repair. If we do, we won't need brain transplants anyway.

    As long as manipulation is done sensibly, i.e. without severe loss of gene diversity, and slowly enough for corrections to be made, it's not really such a bad thing.

    I don't understand your stack of cards analogy.

  • Yes, the brain gets old with old age, but is this due to the brain itself, or the body not being able to support it and keep it fresh?

    Oldest woman said to have a brain indistinguishable from a 30/40 year old, no Alzheimers.

    The brain is one single organ, if we only had to look after that obviously we woud give it loads of more attention.

    If that is done many more corrections could be done, as we have decades more of youth.

    Decades of more youth, = decades of less damage, and more fixings

  • The brain's degeneration is also due to the brain itself.

    Put simply, every time a cell divides, it looses bits off the ends of it's DNA. Cells have a finite lifespan. Hence every organ, including the brain, has a finite lifespan.

    (During meiosis bits of DNA are added to the ends, which is why kids start fresh, but dolly the sheep was born old.)

    If we can't fix this (e.g. with immortal jellyfish genes), we can't be biologically immortal.

    If we can fix this, we can stop aging anyway probably!

  • Well, as i've said, even if we could stop ageing, we would still need brain-transplants, simply because it is a, 1 fits millions of serious illnesses with no cure, solution, obesity, unattractive people, or people who simply want to change, brain transplants sits at the ultimatum of human progress. Yes, but you haven't responded concerning Ms. Edna Parker ,which neurologists proclaim was less than half her age.

    Yes, the brain itself too, but systematically nearly all from the body.

  • I don't see what there is to respond to. She was healthy and probably had good brain preserving genes too.

    Yes, functioning brain transplant would be cool. Note however that personality is likely to be deeply changed by hormonal differences.

    Well, if you consider that blood-related issues are "from the body", then I guess yes.

    Using frozen brain "stem cells" to rejuvenate the brain might be effective, but there's still a theoretical limit on lifespan that way (even if it's 1k years)

  • deeply?? brain = person, it's the brain which is conscious and sentient, not hormones, hormones are completely irrelevant. If you get a bigger pair of balls, so what, you'll still be 100% you & a bit more.

    1k years? remember how far we came in only the past 100, or even 10???

    harvy thinks that only in the next 30 years brain rejuv would be possible to repopulate dead brain-cells

    the brain is the most valuable machine in the universe, everything should be done to preserve it and keep it well,

  • I'm sorry, but changing the hormonal balance is a big change. Just think of how differently some women behave depending on their cycle.

    Note that there's loads of hormones floating around that affect everything from pain perception to attention span and "energy"

    Here we're talking about a whole new young body for an old brain.

    You don't NEED to preserve brains, you can always make new ones. Let's not pretend that the quest for personal immortality is an act of moral generosity.

  • Not all woman, and their cycles don't mean that they are other woman all of a sudden, they are still the same person. Hormone levels change daily, hourly, nothing of concern there.

    NO, I am infinitely important, and i would only expect every other fair person to state the very same. I won't care for people who don't exist.

    And yes, BTW it is too, very much so, thinking of studing 30 years of your life and only working 20, is very ineffective, death is a library burning.

  • Indeed, death is a library burning.

    On the other hand, if humanity were a stagnant population of immortals, prejudice and wrong assumptions would be much harder to tackle. Society would adapt more slowly to change.

    Nothing is infinitely important. Except maybe life itself as a whole.

    Btw, i AM pro life-extension, brain transplant, GM humans and cyborgs. I just think it's important to look at the problems too.

    Maybe living forever as software would be a decent compromise?

  • Such as that Nazi guy who brutally murdered 35000, what punishment are we going to give this 89yo now? I think that immortality would give people only more concern for doing the right thing, as now the punishment would be able to be more fulfilling.

    Yes, my life is, and every other fair person too. This means that i would do anything to preserve my life and those and those of other progressive people.

  • SOFTWARE, i am not a computer program, i am a sentient person, and all sentient fair, non-ignornant people should be preserved to the highest standard, the standard which has vigorously designed them over the past 3 billion years.

    We are the only sentient ones, we are the only ones which care, Without us, the universe wouldn't matter, and because of this, we should look after ourselves and of others who collaborate.

    We ARE the supreme masters of the universe. AND WE SHOUD ACT LIKE IT!

  • Sorry, but the "nazi guy" is a very bad example.

    Even if he thought that he was going to live longer, he would still have done it.

    Unless you think that the point of social punishment is revenge rather than prevention through fear, there's no argument.

    We are NOT the only sentient animals. Please give me one reason why you think that chimps aren't sentient.

    Why should the "natural" standard be the highest? I think that being more knowledgeable, smarter stronger etc is probably better.

  • No, it is not, yes it is revenge and justice needs to be served, and yes punishment stops psychopaths from doing things they would normally do, could you imagine a world without jails?

    Yes, point taken, but so far only two other mammals are recognized as sentient or possibly sentient, those are bottlenose dolphins and great apes. We aren't even sure if all humans are sentient, considering how illogically demented some are.

    Yes, but only if it is as an addition to natural and in a natural way

  • Revenge accomplishes nothing. Punishment can not be a retroactive deterrent.

    Actually, there's pretty good evidence that many mammals and birds are conscious beings. As for emotions, anyonw with a pet dog would contraddict you.

    You think like the greeks who, not being able to understand the barbarian's language, assumed they were retarded cave-men.

    Why do people have this crazy idea that "natural=good"? There is no natural way, unless you make GMs through nazi-style selective breeding,

  • There is no real measure for sentience, all i know is that i just ate a chicken burger, but does that make me a brutal murderer, perhaps, thing is that we don't see any reason at all for considering these as sentient, as far as formal psychology goes, only considered sentinet are: human beings, some elephants, some greateapes and bottlenose dolphins on this planet.

  • You see, this whole "It's ok to kill animals because we're awesome and they suck" thing seems to be one of those examples where the moral rules are constructed to fith with behaviour instead of the other way around.

    If you can understand that your reflection is you, then you're conscious.

    Emotions can be seen through a cat scan and are actually just manifestations of extremely primal/basic animal instincts.

    You have to draw an us/them line somewhere (family, race, species) but it's arbitrary.

  • ALL IM SAYING IS THAT IM A SENTIENT BEING, i know that i am, and i think that i am fair too, i would only care and want to best for myself ad other sentient beings, i am not concerned with those who don't exist.

  • Yes, you are a sentient being... I'm just saying that that's not as special as it sounds.

    also: "i am not concerned with those who don't exist."

    I am concerned. For example, if I had the opportunity to get 1000$ at the cost of making planet earth uninhabitable in 500y, I would decline the offer. Even though only hypothetical future people would be alive at that time (probably).

  • scarcity creates abhorrent behavior, or what you call "criminals." eliminate scarcity, and less criminals will emerge.... but unfortunately, even dogs eat there own vomit sometimes. justice is the act of punishing people without getting to the root causes of their behavior.

  • so there are no bad or ignorant people? wake up

    i have put this theory to the test countless times, there are plenty ignorant and viral fuk nutjobs on this planet

  • everyone's behavior is environmentally driven, and that is irrefutable. in the roman empire, it was completely acceptable for families to go watch christians get fed to lions. the children would ask their parents "can we come back next week and watch more christians being fed to lions?" and the parents would say "only if you behave" were those children bad or evil? the parents? putting a theory to test is not an understanding of other cultures through history.

  • no it is certainly not, i am all too certain about that. even if this is most people it is not all. ignornace is what makes people this way, ignornance is conformity,while the inquisitive always will be themselves. i have always been disobedient, i have never stolen anything either, more than half my frinds are deep drug adicts, i don't even occasionally smoke, my mother wanted t ocall the priest when i told her that i was a vegetarian

  • and where do you think ignorance comes from?

  • yourself. I was born into a downright strict highly religious family, dead close minded culture, i've always thought for myself. i bet you, near 99% of the people in my childhood, all closeminded.

    We ARE NOT ROBOTS, people we are SENTIENT.

    Sentience is who we are.

  • furthermore, you do not know the life story or this mr. fritzel person. since either one of us know exactly what motivated him to do what he did, and that we do not know the lineage of his gene pool, his circumstances should not be a part of our debate. just about 65 years ago, the majority of people living in his region of the world were quite happy putting jews in an oven to burn alive. where did they get that idea from?

  • Think about it this way, what do you say about some Jhosph Fritzel? he is categorized as mentally well and healthy

  • sure he was, so was charles manson. enslaving women for sex was once a socially acceptable act in many cultures throughout history. spartans took their wives by force, it was the law, they called it marriage, and they were known for protecting the future of western civilization. even today, sex tourism runs rampant in countries like thailand, why is no one locking those people up? not saying it's right, i personally don't think it is, but it is what it is. acceptable to some, and not others.

  • sex tourism, so what? the spartans gave one f the most rights to woman, and no they did not fuk their kids. this man was living in smack center of a western liberal well developed nation, he was also considered psychologically sound, there is no cultural effect here.

  • sex tourism in thailand IS fucking lil kids. i know, because my mother was one of them. it's possible, right now, to purchase a child (5yo-17yo) for very little money, treat them how ever you wish, and no one has done anything about it in 70 years. it shows that unless you have been SHOWN WHY it is wrong, you don't know it's wrong.obviously, some people just don't get that message, or get ingrained with a different message from birth. not always cultural, but definitely environmental.

  • very sad to hear about your mother, it should happen to nobody, and nothing justifies it. But no, this is not the same as fritzel, fritzel was in the center of a western, secular state. no, he obviously knew it was wrong, he even killed the child too. and no, ignorance again plays a part, people are either ignorant or they aren't, it's independent of culture. ignorance makes the environment and culture take the lead, knowleage seeking people r always themself. u claim that sadists don't exist?

  • of course not, but it is an empty distinction. our argument is that this kind of behavior is either brought on by birth or environmental influence. i claim that it is by environmental influence, and i have submitted evidence to my claim. you have not.

  • and the same applies to people today. a person of chinese decent, raised by southern family deep in the alabama country, would take on a southern accent, hold southern values, and most likely not ever learn how to use chopsticks.

  • and? no i am a coloured south african, everybody says that i 'act white' why is this? and secondly, why don't you thik that people are guilty fo theri actions regardless, because it is ignorance that makes them be like sheep, the non-ignorant are always one in the same. ignorance is the worst and only evil as Socrates said. this is what makes the sheep

  • i think that chimps aren't sentient, because they aren't smarter than us. they are a transitional form of us. just because they walk and talk and use tools, doesn't mean they have the ability to critically ponder their own existence.

  • You don't have to be smarter tha a human being to be sentient.

    I think we can agree that 6-year-olds are sentient, despite being retarded by adult standards, and not spending much time critically pondering their own existence.

    In fact, I bet that the peasants of 1000bc didn't spend much or any time pondering their own existence... because they were too busy trying to feed themselves.

    What type of sentience are you looking for? Self-consciousness?

    Why doesn't the use of mirrors convince you?

  • thats a good point, it's not about intelligence at all, but we have found inscriptions on rock tablets from 1000bc, there were obviously one or two even back then who wondered about there own perception. we are the only creatures on this planet that have the ability to ask "why," and solidify ideas relevant to that on an external medium. can a chimp do that? i've seen an elephant paint, a cat play piano, and a bird that can dance... i wouldn't call that sentience. am i missing something?

  • your a idiot. just stop thinking and talking. oh yea and read a book do some research

  • thats not cool... what did i say? i read lots of books.. jeez i was having a conversation... i wasn't making any real assertions. please enlighten me, oh wise and powerful asshole...

  • hey, c'mon... whats the matter, dude. you can tell me. i don't have any thing else going on tonight. i'm not mad at you about what you said... but i am concerned. youtube can take a hell of a toll on newbies.

  • Sorry but that's just unfair:

    "We can write, animals can't, so in absence of proof of the contrary let's assume that animals aren't sentient"

    Let's not push the burden of proof on either side, and just compare the evidence.

    Evidence for animal sentience:

    They can plan ahead.

    They can recognise themselves in a mirror.

    They can sacrifice themselves for a greater good.

    They can communicate

    Crows learning to operate a vending machine and to read traffic lights.

    We don't know if they ask why or not

  • excellent debate, great points on both sides, but you know, i did some further research and i discovered that you are right, animal sentience does exist. thank you, i learned something new. peace be with you.

  • "they" not all animals can do that, and bacteria could also communicate, sacrifice themselves for a greater good., this means that bacteria is also sentient? again, as i've said, animal psychologists only recgnise bottle nose dolphins, elephants and great apes as sentient.

    as a todler, 1 years old, you could also do those things, however you weren't sentient.

  • I've just realised that i am a cold blooded murderer for odereding a bigmac

  • "I've just realised that i am a cold blooded murderer for odereding a bigmac"

    I console myself by thinking that the animals probably "prefer" living in captivity and being eventually eaten rather than not existing at all.

    I would. (At least I think I would)

    Plus... meat tastes good. There is, somewhere, a fair balance between quantity and quality of life.

  • Comment removed

  • i love big macs. did you know that the cow was once a fierce and dangerous animal? through cross breeding we've domesticated them to a point where now, tehy would go extinct without us. it's interesting to note that bananas used to have thorns, but through cross breeding, we have made them more edible and abundant. marijuana has the same concept. twenty years ago, a pot plant contained about 4% THC. now there are plants that contain 40% THC.

  • I'm not sure that cows would go extinct. In many areas they would have no natural predators (we killed them all). And cows are really good at eating grass...

    However, they'd definitely have a hard time, and that's even more true for other farm animals.

    (I wonder if dairy cows would die of milk acumulation, even with a teeting calf)

    Are you sure that bananas used to have thorns? I had heard that the problem was that they were mostly seed (with little pulp).

  • yeah seeds, not thorns. you're right.

  • Harvard Med:

    "in the next 10 to 30 years, scientists may be able to "repopulate" damaged areas of the adult brain with new, functioning cells born of the person's own precursor cells. When and how well such a tactic would work will depend on the type of injury. For instance, according to Macklis, some spinal cord injuries may be repaired with a relatively small number of neuronal connections and should be easier to tackle than a complex brain disease like Alzheimer's."

  • Alzheimers ?

    This acts more like a virus, latest research shows that it may be a derivative from the cold flu virus, meaning that the cure may well already be literally around the corner, at your local pharmacy.. research is still underway, however a vaccine may be just arond the corner, if not already here (one worked well in mice).

  • this way: the brain is one organ, your body has thousand, anything could go wrong anywhere, be it one of the thousand types of cancers, or any other illness, these effect your body because it's age it's ageing, rejuving your existing body won't be that effective(albeit still brilliant) that well, because some or other illness almost certainly will still get hold, you don't forever fix a broken car, (even though the body is trillions of times more complex), the driver gets a new and better 1

  • Yes indeed.

    Empowering individuals always leads to some degree of social instability.

    At one extreme, you can make sure that the primary concern of the population is feeding themselves, that way they'll never have time to mount any kind of rebellion or even organise themselves into killing each other.

    At the other extreme, each individual has the power to destroy the world... and someone quickly does.

    Hopefully, we can cure psychopaths, anger, despair and impulsiveness BEFORE giving power.

  • What he is suggesting is the same as letting rabbits into Australia. These guys are pernicious in their myopia. There is a reason for kids not being able to repair a car-engine or play chess straight from the womb.
