  • All of these comments are boring. Zzz.

  • really informative and interesting

  • This is a great video

  • i highly respect this man, only if there were more like him in the world.

  • Homosexual activists understand the power of words.

    Please visit my channel to watch a one-minute video clip in which popular atheist author Richard Dawkins admits that homosexual activists "hijacked the word 'gay'".

    The word "homosexual" is more appropriate and accurate because it, unlike the word "gay", actually describes the behavior/attraction/relationsh­ip being discussed.

    The word "gay" helps homosexual activists push their agenda.

  • @lightandbeautiful umm what is wrong with you?

  • dam, i mistook him for a hat.

    

  • I love TED talks.

  • Respect.

  • I wish Oliver Sacks was my grandpa... my grandpa sucks

  • What do u know.. a doctor who knows what hes talking about..

  • I have read some of his books. In Musicophilia he mentions what he did in the 60's and he mentions taking psychedelic drugs as well. Think about that! For those considering taking drugs that can teach us about the mind, you should :)

  • His books are great!

  • I am not so quick to write these off as seemingly meaninglessness noise or static in the non seeing eye...

    I have no sight impairment and I can see all these things by just closing my eyes and using my imagination.

    Add some psychedelics to my mind... and all bets are off... I am in a completey other world... Full of vibrant colors and shapes and tapestries and limitless forms of art and sounds... I have never seen anything that even comes close the same beauty in the "real" world.

  • I can close my eyes and see entire landscapes and fly around them... I can see a market scene with people walking about buying and selling things....

    so what is that?

  • @batfly Depends if you control the images or if they control themselves. I can imagine stuff but i decide what happens next.

  • @batfly It's the market people selling buying things syndrome

  • Without wading through all 246 preceding comments to see if this has been asked before - does anyone know if this affects those who have been blind from birth (and have never, therefore, seen "real" people? Does one have to have a visual "memory" to get these hallucinations?  Does it only affect those who have had normal vision and who then become impaired, eg via macular degeneration?

    My Dad has Charles Bonnet syndrome, diagnosed by his neurologist several years ago. He is almost 98

  • @OriginalNightStalker I wondered the same thing. I bet you can find the research somewhere--maybe you can search Oliver Sacks and find his research and etc.

  • what an amzing man oliver is, would love to be his pupil! also hes so cutee!

  • 31 people brains hurt

  • 31 people obviously didn't watch the video.

  • I really like the way they have him (or he has himself) sitting in this talk, as opposed to other ted talks. You can also tell that he is so engaged in what he is saying when he is leaning forward towards the crowd. He must have the luckiest grandkids... haha

  • super good info, but...i have temporal lobe seizures and I've never been transported to the past, damnit! :/

  • I just want to take oliver sacks home and give him tea and cake....

  • But....Kermit is a puppet...not a cartoon.

  • I do wonder if this is the cause of the visual hallucinations many people have - specifically the tiny dots that many people seem to have.

  • NOOO!!!! This means I have a Justin Bieber cell!!!

  • @Usernamenottaken2k I think everyone has that.

  • @Usernamenottaken2k My God, I look up a sophisticated neurology talk and I STILL have to read people bitching about Justin Bieber!? Unbelievable.

  • I like the way he replaces his "r" with "w".

  • @haemishripper i used to do that

  • Anarchic is correctly used in this context

  • What's with the 28 thumbs down to Oliver Sacks?

    Oliver Sacks books are brilliant. I don't get how on earth a person could thumbs down this beautiful speech by Oliver Sacks on the subject of hallucination.

  • @ogrish84 what I don't get though is, why you should care :) ....Sacks' true greatness will be recognized long after his death...let the dumb look after themselves.. :)

  • Comment removed

  • Excellent speaker, very interesting, and with a very engaging topic.

    And he knows how to use 'anarchic' in a sentence, unlike certain people who commented on this video.

  • I wonder sometimes if the people experiencing these Hallucinations are sort of looking at life in a different dimension. Maybe there are hanker-chiefs floating around us all the time? We just can't see them? Or ... maybe I'm still tripping from that LSD I took 5 hrs ago... blah

  • understanding ourselves I believe is something which is almost impossible, atleast not completely. it is hard to believe we are compromised of just neurons and electrical impulses.

    follow me @rechenzo

  • Very interesting, but TED talks always seem too short to get into significant depth.

  • Wow, I never knew I'd watch the entire thing but that was amazing.

  • I thought I was completely alone in experiencing this phenomenon! Everyone I've mentioned it to, including the good people at the commission for the blind, behaved as though I'd sprouted another head. To whom can this be reported so more reliable numbers can be obtained?

  • id shit bricks

  • nota 10 :)

  • @Tribune99 I love this man.. I watched Awakenings and read 2 of his books.. I'd love to read musicophilia or The island of the colorblind!! He's so inspirational and he looks kind and caring as well <3

  • The old lady wasn't having a hallucination. She was time traveling. It happens to a lot of people in their nineties, and most of them see Saudi Arabia, because of the staggered time zone issue.

  • He is like the modern Freud!

    He even looks like him.

  • TED brought to you by fiji...

  • Am i the only one who gets freaked out when he starts talking about the deformed faces?

  • Interesting stuff. I'm legally blind and my vision progressively worsens. I haven't yet experienced any hallucinations but I wonder if I may, later on in life? Might be kinda cool, since the TV probably won't do me much good at that point. :)

  • Has anyone read his new book?

  • As a specie's our first communication come from the faces of our caregivers. Meaning we actively engage our senses (physical), and firing synapses to figure out just what the hell that big, weird person is doing! Then life is a journey on which there are many markers, or what I call "event horizons" which are defining in the makeup and development of the human being. Which mind process and dwells until "reconcile" or "deforms". see next post

  • @iBelieve0and1

    Cartoons are a great visual representation of a "different perspective" Or really it's prolly just that cartoons are the way kids are exposed to the all mighty T.V.!! Plus animation is different than what they have been exposed to thus far in their short lives, or a "event horizon" that sticks with them.

  • @iBelieve0and1 Maybe the simple colours of a cartoon are easier to process for a child's brain, which is developing. I don't know.

    What do you mean by "event horizon"?

  • I have hallucinations...schizoaffecti­ve disorder... i see a person, feel,smell,hear and taste all that stuff...... The guy that I see will walk up behind me and grab my shoulder and then run about 20 ft away and then stare at me then walk away......

  • Awesome! The brain is so funny sometimes.

  • Bravo!

  • When I was a young kid I was sitting down tying up my shoes, I looked up and there was a green man with white hair wearing a white robe. He was completely solid, feet on the floor staring at me. He just stood there less than 6 feet away. He disappeared right in front of my eyes He attacks me all the time. This is no hallucination. If I do kill myself it is just to get away from him and all the people who laugh at me and won't help (doctors included). He is completely real and we aren't going

  • Dr. Oliver Sacks is a fascinating man.

  • All i need is tedtalks and that sweet sweet herb to keep me entertained for hours.

  • I wonder why, under the influence of hallucinogenic drugs, we see the particular things we do. Or, never mind the drugs--just the hallucinations that some people have accompanying dementia, for example. What, in the brain, creates the particular hallucinations any of us has? This is like our dreaming...where do the ideas and stories come from???

  • @nannygoatj could dimethyltriptamine play a role?

  • Who downvotes these? Some kind of cunt? Christ.

  • @linksysrouted

    Some people have a hard time taking in information that actually has to be processed by the brain. You can usually spot these people by phrases like "huh wtf is they talkin about? This is stupid *thumbs down*"

  • They have some good lectures on TED but, they also have a lot of NWO poverty pimps on to spout their bullshit as well. Beware of TED!

  • @green4us2sm0ke

    Excuse me pal but i dont believe tedtalks has ever talked about NWO. Prove it with a link or you crazy mkkay

  • Read his books; they're marvellous.

  • He has a very intelligent accent I like it.

  • if saint paul hadn`t have the hallucination of jesus ...there were no christian church today.

  • You're right whendirtgetsinmyeye. He's wearing cool trainers at 16.50 too.

    He's also an open water swimmer. Whilst doing this he does a lot of his thinking and this makes him want to write.

  • Sacks is the man.

  • Unlocking the awesome power of the brain is a worthy aim for science. Subconscious exploration still hold a lot of secrets.

  • What a delightful and eloquent man.

  • @whendirtgetsinmyeye AGREED. He speaks so well!

  • @whendirtgetsinmyeye omg he seems so nice i wish he was my grandfather!

  • The world is in your heads!

  • that Fiji water musta done some miles before it got drunk at TED

  • hes so cool, I wish he was my grandad

  • very interesting for a geezer, 5 stars

  • your tool sar so very limited to explain many of these things.

  • very interesting!

  • 666 ratings!!! this is the devils work. whohhahahaha

  • Sacks is very lucid in his exposition.

  • 13:50 "There is a part of the brain which is especially activated when one sees cartoons. It is activated when one draws cartoons, when one watches cartoons, and when one hallucinates them."

    Could someone elaborate on which part is activated, what the lasting effects of this may be, and if there are similar occupations or observations which trigger the same region as cartoons? ...is this a good thing? --I like drawing cartoons...what's going on with my brain when I draw them? : )))

  • you focus...

  • how do you know this? I wrote to him asking...specifically about drawing cartoons...has he elaborated upon this explicitly elsewhere? thanks

  • im very sorry but i was being a smart ass, i made that comment before i watched this, sorry..

  • sorry friend, i don't know if i'm misunderstand what you are saying or the other way around haha (most likely my fault). but to clearify on my side, i wasn't talking of the number 23 being an actual hallucination. i was saying that some people say that it appears on street signs, bill boards, t.v. etc. and those people think it means something. but infact they are noticing it everywhere because they THINK it means something. i was wondering if hallucinations manifest for this lady because...

  • she's constantly thinking about Kermit, regardless of whether or not he has some sort significance. the women is constantly thinking of him so could that be why he manifests in her hallucinations so often?

  • i'm sure this gentleman has already thought of this, but in the instance that the women who hallucinated Kermit, she says that he has no particular barring on her, he has no weight so she didn't understand why he keeps comming back. Is it possible that he keeps appearing BECAUSE she saw him once and thought about him, and he appeared again and it snowballed after that? much like one can hear a word one day but that same word seems to pop up again and again because they are conscious of it.

  • in the same way some people seem to have the number 23 confess to them in their day to day life or a un/lucky number of any sort. Is it possible that Kermit manifests because this women semi-obsesses about him being unimportant?

  • Well I think these "hallucinations" have some reality to them. Perhaps by some process of the mind, they "guessed" that they were going to see the number 23 on which days. Perhaps in their everyday life, they see this number a lot, then they get their minds to focus on it involuntarily. Maybe this relates to hallucinations whereas hallucinations is a stronger rendering of the minds faculties to this process. There are many monotonous things that people ignore in an average day.

  • Can't anarchic mean 'lacking order or control'? I wouldn't have thought there was a problem with his use of the word. I think he's a good speaker and I found what he had to say very engaging and thought-provoking. Seems a pity a dismiss all of what he has to say because of one word.

  • @HerzogsShoe You're right, but the original definition of Anarchy is "1a : absence of government"(Merrriam-Webster), but a common propaganda definition, still in Webster's, is "1b : a state of lawlessness or political disorder due to the absence of governmental authority", anarchic meaning like anarchy, i.e. lacking order. This is propaganda because it's against the state's interests to have people believe "1c : a utopian society of individuals who enjoy complete freedom without government"

  • @HerzogsShoe

    So whats your problem? That definition fits perfectly in the context of what he was describing.

  • @ajnode No problem, I was replying to previous comment. Like a year previous.

  • @HerzogsShoe were you defending his use or bringing this up as an issue of your own?

  • @HerzogsShoe

    I think the reason why he used the word is that the one with the syndrome has no control over the hallucinations.

  • sorry man but what does a libratarian know about anaarchy a movement defined by movements like that of Bakunin or in modern mass cutural movements who resent the government having the right to rule them all the libratarians care about is the right to tax

  • Libertarians are a very mixed bag. Personally, I read Bakunin (among many other things). Libertarian individualism, and all the philosophical premises of libertarian thought sync rather well with leftist anarchist views..

    unless of course they get dogmatic, and spout prejudice against the term capitalism and conflating it with corporatism...

  • i think he was just using anarchic in terms of visions seemingly lacking governance by the brain, lacking coherence. anarchic, all-over-the-map visions.

  • Yes, and if someone is sinister, they're being left handed...

    Semi-decent tirade until you misunderstood how words evolve.

  • tirade? i understand how words evolve. you're reading too much into his.

  • good advert for FIJI water there

  • he's always been such a wise, compassionate man

  • I hallucinate often that I am a 28 year old man who goes to work everyday and comes home afterwards...sometimes I even go to the gym on certain days and they get really weird sometimes when I hallucinate that I go to dinner for Tappas with my Fiance on occasion. These are my usual hallucinations....but occasionally I see other things...like the beach and ocean this past summer for about 4 days over a long weekend. I hope to hallucinate about Paris next Summer but we'll see if I can afford it.

  • we still i think know very little about hallucinations, we know almost nothing about our own consciousness... I see vivid hallucinations, on psychedelic drugs... entopic patterns and everything.. Dr. Rick Strausmans studies using DMT are particularly interesting...

    check out DMT the Spirit Molecule

  • YES! I'm not the only one who reads rick strausman's studies! DMT is amazingly mind-opening and very thought-provoking as to its natural occurence with life and death

  • don't ever listen to people on youtube comments that think they know anything about hallucinations.. since just exactly what a hallucination is currently unknown in science... there are some competing ideas.. but very little actual science on the issue or consensus dreams are a kind of hallucination and in theoretical physics the idea of multiple realities and parallel universes are perfectly accepted. not that these are places one could go of course but its interesting what we count as "real"

  • Sometimes when I read while I'm kind of tired I hear music, and it's music I've never heard before!

  • I used to do that when I was a teenager and it's kind of spooky because now all the songs I heard when I was younger are actually being released...

    Or maybe I'm just reconstructing that memory, either way it's very interesting!

  • This is one of the most interesting TED talks!

  • What if they are not hallucinations but glimpses into parallel universes (which are real according to current thinking in physics). Perhaps the visual cortex neurons are so hypersensitive they are reacting to stimulus from overlapping dimensions.

  • No

    First of all we have instruments far more sensitive than the eye and if such a thing was going on we would have detected it long ago.

    Secondly parallel universes are not 'real' according to 'current thinking in physics.' Thirdly even if there were parallel dimensions the likelyhood that the laws of physics would be comparable and therefore lead to coherent images in this universe are infinitesimal. Fourthly overlapping dimensions and parallel universes are two different things.

  • prepare to meet kermit the frog on the 11th dimension

  • I'm 21 and I hallucinate all the time.

    I think you need to do drugs at some point to set them off, to make you more aware of them.

    I like how they in no way relate to what I'm thinking about.

  • If this is true it is most likely a form of psychosis (sometimes triggered by drug use). Consult a doctor immediately.

    In some way the hallucinations will be related to deep seated beliefs, and will be related to some extent to what you are thinking about. The most important driving force for both your thoughts and 'hallucinations' is your mood and emotional state.

    A good mood will result in markedly different thoughts and hallucinations to a low mood.

  • church...

  • "It's a silent dream

    It chooses the weather

    of your soul stream"

  • alguien puede ponerle subtitulos a estos videos??

  • Dr. Sacks is perhaps one of the most intelligent persons of our century. I read his book "the man who mistook his wife for a hat" and was extremely impressed.

  • To take off from where the speaker left off, i.e. how these hallucinations tell us about the correspondence between structure and function in the brain, watch V. S. Ramachandran's TED Talk. It will leave you stunned.

  • As a game developer, I'm worried I might start seeing non-existent polygon edges sometime in the relatively distant future.

    That, or game monsters (in which case I'd probably kill myself in a way that doesn't invoke hallucinations).

  • I worry about the very real danger of getting stuck under some stairs and having to wait for an enemy to come along and kill me so that I can spawn at the last checkpoint. Also, I don't like to get to close to fences because I might get stuck in some clipping corner and ejected through the ground. Falling forever looking up at the world seems pretty messed up.

  • I've been caring for a man describing these same symptoms, but I guess it would be useless to inform his nuerolegist. Seeing as how theres neither a cure nor a treatment. He'll be satisfied enough to discover he's not crazy.

  • why on earth would you want to stop having hallucinations??!!!!

    They are great. i have had some really excellent ones. Once i had an audio hallucination while i was in the toilet. I heard a sports commentator commentating on what i was doing. i didn't want to leave the bathroom because it was so funny. But i did and when i returned a few minutes later there was no commentator :(

  • lucky dog.....

  • Fascinating stuff, theatre of the mind.

  • Acoustic Neuroma...Has anyone had 1 or more operations to remove a large one? Have you experienced any of these symptoms?

  • Fascinating stuff.

  • O-Ke-Doke

  • Interesting to know but sounds quite frightening or weird to actually experience them! Not very common knowledge but could be a common phenomenon. Thus those who had gone through them might be reluctant to share ...

  • Another great TED. 5 stars

  • It sounds a lot like the auditory & visual hallucinations older people get who have been bed bound for a long time. It seems to have something to do with sensory deprivation & the brain somehow compensating for the loss. Sort of the way people with brain damage confabulate memories to fill in the gaps of what they can't remember. It seems that the brain needs what the brain needs & is always striving for homeostasis. I love Sacks & his ability to explain the complex & make it appear simple.

  • shame on the medical profession for keeping this overlooked

  • Those hallucinations sound freaking horrifying.

  • wow great talk. very interesting

  • Search Youtube for HOW WEED WON THE WEST

  • i dont see what you are

  • The title is an incomplete sentence...

  • no it's

  • what are you talking

  • So all of this comes down to one word : Dreaming

    do the math...

  • I have exactly the opposite sort of hallucination. I see things that nobody else sees and I can ask them about them and they say there is nothing there, but when I reach forward and touch them they become real and then they are seen by everyone to pop into existence with much consternation, amazement and how did you do that. It seems to happen most while shopping at thrift stores or old, shabby boutiques where temporal tracking is loosely coupled to physical reality.

  • haha sure you do

  • You're probably a schitzo.

  • Nah, I just see thru the haze that old people get when they mass hallucinate things out of existence...

  • Wow, at the end there he took the idea to the place I'd perked up at 14:00 for. I was wondering if the area which reacts to cartoons reacts to drawn figures of animals and people in general. Since anthropomorphism of animals and objects is common both in cartoons (comics and animation) and in many shamanistic traditions... it could be a similar area of the brain being stimulated by such images. Since I know not all people react to animated entertainment, I wonder how that relates.

  • OMG IT'S SIGMUND FREUD!!!

  • It's simply called DMT.. We all produce it EVERY night. Some may produce it at will when in trance from i.e meditation. Good to see this has become more and more clear for people. This is GREAT! Hopefully we can unban the of DMT as in other tryptamines. Abt sad that he does not even mention DMT in all this, maybe he don't know. Some call this experience "your higher self" He need to read Rick Strassman - The spirit molecule. Thanks for this talk TED! Peace
  • Fiji water? Arggggg.

  • wonder how much FIJI water paid TED

  • enough

  • Cataract surgery back in the 1800's????

  • I was thinking the same thing. I had no idea.

  • How many senses do we have?

    It's not just the traditional five.

    1. sight (visual sense)

    2. hearing (auditory sense)

    3. smell (olfactory sense)

    4. taste (gustatory sense)

    5-8. touch: The skin senses

    Because touch involves four different sets of nerves, the skin senses are considered four separate senses: 5. heat 6. cold 7. pressure 8. pain 9. motion (kinesthetic sense)

    10. balance (vestibular sense)

  • 11. proprioception

  • Why did i get thumbed down for saying we have more than 5 senses?!!?

    Are people stupid or something?

    Equilibriception is a sense, pain is a sense, heat is a sense, etc etc etc... So thats more than 5 already.

    I get thumbed down for talking science. Nice.

  • Nice name.

  • Its a useful phrase if you live in Texas...

    I use it alot.

  • LoL I imagine.

  • Oh, I should explain...

    Sometimes my room would become an utterly mesmeric, vast landscape (a desert?) in which I had the feeling I was a small as an ant. It was quite an unpleasant feeling.

    Other times there were patterns which were quite unsettling. I can only really describe them as rough and spiky textures in pale colours.

    I also saw cartoons - related to the ones I watched as a child. I would often see characters walking across my room in a silent procession or acting out some scene.

  • I have had very similar feelings as a kid, while having fever. My room seemed to be so big it would take years to reach the other corner and every task involving moving to other part of the room just seemed impossibly troublesome. very unpleadant feeling indeed.

    And your description of patterns reminds me of how some surfaces felt when touching. again weird and unpleasant.

    Haven't had those feelings after childhood :( alltho unpleasant they could be fun to analyze as an adult.

  • had the exact same feelings as physicologsphy describes :D but all sounds seemed simply angry and agressive, i suspect it was panic attacks... often i caused them myself by listening to my breathing :D

  • wow that is exactly what I had as a kid, and yes usually during fevers.

    It is so hard to explain, but what you said sounds about right, i'd have to go from one corner of I dunno my room/the earth/the universe and as soon as I finally go to the other side I realised I actually had to be back on the other side, only it was now twice as far away as it was previously.

    repeat endlessly.

  • I had the same sort of fever induced hallucination but it was like I had to endure infinite massiveness and infinite smallness at the same time... it was horrible... like I/the room/the universe was shrinking and expanding... collapsing and exploding... euuuurggh!

  • Oh..... gosh please don't remind me about that feeling. It was terrible. the "infinite massiveness and infinite smallness at the same time" thing was so hard to endure. glad that it was gone since i was 12. when it happened i could feel or more appropriately see a massive rock rolling down on me then suddenly i see a small little tiny needle spinning vertically..... tell you guys that feeling really sucks big time.

  • When people recount the images they see... it sends a shiver up my spine (in a good way). There's something mysterious and captivating about it all.

    I used to hallucinate when I was a child and had a fever. I've asked many people if they experienced the same and so far, no one has.

    Can anybody directly relate to my experience??

  • So Charles Bonnets grandfather had cataract surgery in the 1750s!! I am surprised to hear that this was done at such an early date, but wonder how many died of infection or complications. The truth is always stranger than fiction!

  • No ideas really. Just long boring story and some information, which can be sumed up -

    Sensory depravation often causes hallucinations.
