10. Introduction to Neuroscience I

[tabzist]

this is a good lecture

[dimcoin]

The rap was the perfect ending to that lecture.

[PoliticalHell]

I think neuroscience is one of the most important fields of science. If we ever learn how the brain works down to a mechanical level, imagine the possibilities - medical: cure mental diseases, get the brain to cure its body, insert or extract knowledge... computers: reconstruct parts of the brain to create true AI... just wow. I hope I live long enough to see some progress in this field.

[secretbonus]

@PoliticalHell The thing about neuroscience that's most interesting to me is tracking the brain developments of people from different backgrounds and see how their brain develops during learning and brain development. Taxi Drivers show brain growth in the Hippocampus or musicians show brain development in motor and auditory areas. If we could tap into that and perhaps we could artificially accelerate learning in specific areas someday.

[jamesreling]

thanks for posting this. the hip hop video at the end was a hilarious surprise. you guys did a good job lecturing.

[somethingfox]

"Why did the chicken cross the road? Many scientists approach this question in different ways. " WTF??!!??

[giselle21able]

Is the entering of either positive or negative charges a randomized occurrence? Or is there a chemical reaction behind that as well?

[thedeathly]

@giselle21able i think it is caused by diffusion

[giselle21able]

@thedeathly

Okay thank you.

[Youanden]

Hold through Anthony's lecture. It took me 6 minutes until I started picking out the relevance from his words. And to the video at the end: WTF?

[TheRealCardshark87]

i think this guy is a homo

[JoshuaR22]

@TheRealCardshark87 Who cares? He's just spent an hour being articulate and explaining science. You get to say one thing and its "he's a homo". At any rate, what I'm trying to say is: no matter who he is, anything he says seems like it would be much more valuable than anything that could possibly come out of you.

[sacraficialangel7]

@TheRealCardshark87 really? I'd be pretty sure he's straight, or maybe bi. Why does it matter anyway?

[AnimeTV100]

So far it's been review for me, great introduction though.

[ilikepoopitsgood]

I barely understood anything from Anthony's lecture lol Well done Anthony!

[782aew]

Hearing Nathan talk was painful i barely learned anything

[AbortedSheepFetus]

god what the fuck is that sound I keep hearing when Anthony begins his half of the lecture? not to sound derogatory but it honestly sounds like someone is masturbating. I keep hearing this squishing noise. it's driving me nuts

anyway....very interesting.

[qwertypluss]

@AbortedSheepFetus you creep, no surprising you'd think of such a sinful thought with your disgusting name

[k4ur0]

@qwertypluss buttwanker

[InevitableAzn]

lmfao @ the rap @ the end

[bluescouse2502]

great video

[mikeg61288]

Good Job Guys

[MrLazime]

 Anthony Chung-Ming go away from Stanford!!!

[Kindred1a1]

Fucking wow Anthony sucks. I mean its hard to make neuroscience painful but he can do it so well.

[KenMacMillan]

How did the family of H.M. not sue?

[01Nick1988]

@KenMacMillan It was like 1850.....was suing even a popular practice back then?

[KenMacMillan]

@01Nick1988 "Henry Gustav Molaison (February 26, 1926 – December 2, 2008), famously known as HM or H.M., was an American memory disorder patient who was widely studied from late 1957 until his death." From Wikipedia.

I'm assuming that people were nicer than that back then & they just didn't think like that back then. It's also possible that the family didn't know any better. They may have even thought that it was necessary.

[01Nick1988]

@KenMacMillan Ah I must be thinking of someone else, never mind :P

[KenMacMillan]

@01Nick1988 You're probably still right though. Suing was probably just not common in the 50's either.

[jccarbunkle]

@01Nick1988 HM only died a few years ago. Youre probably thinking of phineas gage

[EJNewbury]

@KenMacMillan It's called a release.

[ParisFlorenceVIcky]

i hope i can give such a presentation in my 4th year

Loving the glut-tang clan. Loving the stanford videos in general.

[TheLordTennyson]

... the same organisms. Eventually that would begin to develop language and thus cognition which we can see is present in voila! the cerebellum.

[TheLordTennyson]

...and timing (from that animal running). Essentially the basis for music. There are also studies that suggest that some musical processing goes straight to the cerebellum before the primary auditory cortex. So the animals with the best ability to respond to sounds with an appropriate emotion and timing (in order to run) would be able to survive. Thus developing a strong receptivity to music. This translates to communication as you look at certain animals ability to respond to sounds from...

[TheLordTennyson]

Just kind of random, I think that an emotional response to music evolved earlier than a response to language or communication. Motor movement is involved in the cerebellum, as does timing. When running an animal more or less keeps a rhythm or has a geometric timing. This suggests that rhythm can be processed in the cerebellum. Also when an animal responded to an external stimuli it would hear a sound such as a growl and begin to run, that growl would also create fear combining rhythm, emotion...

Hjernen kontrolerer bare kemiske responser i kroppen og motorikken i biologiske prosesser i organene og musklatur,slik at vi for en fornemmelse av å føle og reagere etter lærte strukturer som lagres i cellene og i de metamorfiske feltene utenpå kroppen som styres av "hjerneceller" i hjertet .dette vil si en reaksjon mellom hjerte hologram frekvensen i et kvantefysisk perspektiv,hjernen har ingen ting med det fulstendige minnet bare reaksjonen av i kemi av det som hjelper diverse cellestrukturer

[helpvidz]

What was the evolutionary advantage of dreaming?

[ArcadianGenesis]

@helpvidz I learned that the adaptive advantage of dreaming is that it prepares us for future possibilities so that when they happen in real life, we will be less stressed by them.

[Saktoth]

@ArcadianGenesis

A nice just-so story. :D

[ArcadianGenesis]

@Saktoth Not really. I don't claim that this explanation is true, nor do I propose that it is verifiable in any way. Nonetheless, it is a rational speculation that might be true, and it has been proposed by actual neuroscientists. It's not like I just decided, "I think dreaming is for this!"

[5dsdouglas]

@ArcadianGenesis I have heard similiar things to explain the advantages of nightmares. I gives the brain the ability to run through very dangerous situations without your person actually have to be in them.

[helpvidz]

@ArcadianGenesis Thank you.

[philoposos]

@helpvidz Dreaming is most probably a evolutionary Spandrel. It's a side effect of the communication between the hypo-campus and the cortex during the sleep. The HC process new events during the day, but these must be sent to the cortex for long-term storage. The storage of the new experiences is made in relation to the old ones. And we are, in some extent, aware of this communication. Eg: you start new piano lessons, and you dream about a pianist you were in love with in your teenagers years.

[helpvidz]

@philoposos Great Answer, Thanks.

[5dsdouglas]

@philoposos I like your explanation and think it may be right, certainly on a physiological basis, but what about atonia or loss of muscle strength during sleep? Is that another spandrel or was is selected for to protect mammals from harm by acting out their dreams during sleep? I guess my question is if a side effect causes an effect is it really a side effect to begin with? I don't know the answer, nor pretend to, thats why I ask.

[philoposos]

@5dsdouglas Well, people certainly can die from therapeutical drug's side-effects. So I would say that a side-effect can be a very "effective" phenomena. Therefore I wouldn't say that evolutionary spandrels don't have effects on the organism. Feminine orgasm certainly have major behavioural effects on the whole gender ; and there is probably a sexual selection for even sharper chins on both genders. So I would go with your suggestion : atonia is a solution to problems caused by another solution.
