He's a professor at UCSD I saw him a couple of times on campus he was always surrounded by students talking to him.
misssweethearted This guy is a legend in the neuroscience community, seriously, I get my PhD in behavioral neuroscience on August 28th assuming I present my dissertation well, I've met Rama once, he's INSANELY smart, like genuinely the Einstein of neuroscience and neurology. He was the inspiration for me to go into the field, I'll be graduating from the 3rd best Behavioral neuroscience grad school at the age of 23 because of his inspiration(yes that is very young), the second best by a small almost negligible margin is MIT, at least in this field, but the first place is miles and miles and miles ahead, and it's UCSD, I'd have gone there but Uni of MIchigan is a lot closer to me and I liked the idea it's the OLDEST neuroscience graduate program. Thanks Rama.
wow congrats dude. Good thing you didn't go to UCSD...it's not a pleasant school. Rama could be at a far better institution like Harvard. He truly is a genius I agree with you. You will follow into his footsteps.
+misssweethearted Why's it not pleasant? I used to live nearby and have a lot of friends who graduated there from the engineering school. One is doing his doctorate in maths. None of them complained.
Misssweethearted is kinda right about UCSD sucking, the students there are generally lacking any intellectual bravery.
I actually worked with Rama for years and am still close with him. He chose UCSD for a few reasons: he liked the weather, the Salk institute (which is across the street from his office) is awesome, Francis Crick worked at the Salk, the UCSD School of Medicine had an emerging neuroscience program, and they pretty much gave him Carte Blanche to do what ever he wants. They also don't make him teach a ton and let him have as many students as he can support.
Since he joined UCSD, both their psych and neuroscience departments have actually out ranked Harvard and are consistently in the top 3 in the nation.
That said, he is only one perspective and there are a ton of other equally amazing scientists with interesting view points who aren't as good of speakers as Rama. Delve in!!!
@@EricLandrum I wish I can meet him someday and actually want to work with him
What Jimi Hendrix is to Rock Music, V S Ramachandran is to Neuroscience.-- original, mesmerizing, and stylish.
If i see anyone getting kicked in the private part immediately I feel a kind of pain and this sends spine chilling experience to my brain. I did not know what the reason is now I know. Mirror Neurons. Vera Level TedTalk. Thanks VS Ramachandran Sir.
we are all connected
I love when spirituality and science come together as one.
Spirituality and science were always together until Religion came.
Spirituality??
It didn't become one, all he said was that it is due to the mirror neurons one is able to feel when other person is being touched(Under the appropriate conditions of course). This just reassures that there is no "spiritual" stuff involved, just plain old neurons firing.
@@dioc8699 depends on how you interpret it ig.
Do the same neurons fire when you 'imagine' being touched or some else being touched?
I'm interested how affirmations and visualization exercises actually work in the brain.
He packs so much into a few minutes. It was over before I realized.
Great presentation. Always love his stuff.
explained beautifully in 8minutes
Mr. Ramachandran is one of the reasons I'm studying neurobiology. Thanks for the video.
i love how he rolls his rs
What a wild accent this guy has, the first syllable 'r' is rolled,and the middle and ending 'r' is American.
Why was there that thing about traffic at the end...?
He's summing up a huge body of research in 7 minutes, on top of a very articulate introduction of the context and implications of the findings. It's confusing if you want it to be cut and dry, but he can't get into nitty gritty details when he's asked to give a blurb.
But it's really interesting stuff. Idk if these are new experiments he's talking about, but he helps phantom limb patients with mirrors to trick the brain into thinking the reflection is actually the missing hand.
he rolls every single 'r' that he says
check out his book the tell tale brain. goes into depth about this, the phantom limbs, and even how autism is caused by damage to mirror neurons. great read
mind-blowing.
So... what if i haven't experienced something and i watch someone that the "something" i haven't experienced.. will is still feel it or experience it?
i love this man's "rr"-s
I sense we are watching one of the "greats"
Excellent Talk!
Vilayanur Subramanian Ramachandran is a so great scientist!
If I rrrrrrech and grrrrab and apple, I rrrrrrecord activity in the brrrrrrrain. Here’s a neurrrrrrron that firrrres when it rrrrrequires that I adopt the otherrrr perrrrson’s point of view. Love this dude’s accent. Adds so much flavor to the talk
WOW!!!!! Just loved it!!
The rest of the lecture on empathy neurons is interesting but subject to a variety of interpretations. His insistence that we are literally connected to each other via our neurons is an argument that completely escapes me. I don't see how his argument leads to that conclusion. Similarly when he says there is no distinction between the consciousness of two people, it is belied by the obviously observable fact that this isn't the case. This has been demonstrated empirically again and again.
Our teacher used this in interpretation class =D It was impossible to take notes! But it is very interesting.
Yeah, fair enough. It's just that I've seen parallels like that drawn before, and they usually end up fueling some religious movement that can then point at it and say "see, science endorses our ideas". The silliest examples are those of physicists referring to "God", and a less benign example would be biologists referring to "mitochondrial eve" and "Y-Chrom. Adam". My point is just that as a scientist you need to be careful to point out both sides of this kind of argument. It can backfire.
Say someone has an amputated left arm and the remaining right arm is squeezed. Will the left phantom arm feel anything or will there be a feedback signal from the right arm that will halt the phantom left from feeling anything?
How do I get my hands on this research!!!

"[if you] remove [your] skin...you've dissolved the barrier between you and other human beings"
i used to skip the ad at the final but i think they are reallt good ads, or are they?, should we check all of those in the vids to asure we dont miss something really awesome or it doesnt worth it?
Wow, cool tangential conversations being spawned from this talk.
I enjoyed the speaker's conjectures. These kind of talks are what originally made me dig TED so much.
It's a rad time to be alive. For thousands of years our species has inhabited this Earth, and only now are we really capable of destroying it/understanding it/physically leaving it.
It's like I've got front row seats to the best show in the galaxy. I wonder if every generation feels this way?
1. Tool use goes back 2,000,000 years ago with the first tools, with slow ongoing evolution of tool kit complexity since. We know that all human ancestors used tools from that time forward without exception.
@jimmayl1
if the amputee has a mirror to his left side, then his right arm looks like his left arm in the reflection...and then maybe if the patient watches his right arm being squeezed in the mirror, he might feel relief in his phantom left arm. there's another vid on youtube where dr ramachandran explains this...he's treated patients using this phantom box (with a mirror).
This is a great explanation of how our consciousnesses are connected through neuro scicence. I love it!
This is truly amazing.
yes, youtube sucks lately, I don't know what the deal is. Not only are videos freezing on me a lot lately, but the "suggested for you" column on the main page has been the same four videos for like a month. Supposedly youtube got hacked recently too...
@jimmayl1 that would be weird because the brain would likely tell you that what u feel is in your right arm. but as he explains it, if you numb your left shoulder downwards, and see others touch their left arm you can feel the touch with the phantom arm..
Gandhi neurons, so profound. No independent arising of phenomena. The correlation between neuro and contemplative traditions is so fascinating.
Ramachandran is my new hero. I LOVE his book, "Phantoms in the Brain". I found it randomly in the library and checked it out twice in a row.
The Talented Mr. Ripley :)
Most of the TED talks take place at conventions, and there are many people slated to speak on a given day. So you must make your point concisely, and then get off the stage for the next person.
I love ram.. one of the brightest around.
Stunning information in this talk!
@TimothyStuartRiches It's kind of like some French people I know who can't pronounce the H in "home", but add an H to words like "even" and "odd" making them "heven" and "hodd"
@Yakko12345 He was your lecturer?!! I'm so envious. My psychology lecturers were so uninspiring.
The more science that is done to research the human brain, the more of the mysteries of the universe that we will understand. I recommend reading a book called, " The Biology of transcendence". If you enjoy this type of thing? There is so much that can be learned from the human brain!!!!
Love this Guy !!!
I am watching the mirror box being used in the stroke unit where my mother is .
Vancouver Island , Canada .
Hey did you see any improvement in patients ? I'm physiotherapist pls do let me know
@@Mulmulmist Yes there was improvement in the fellow. It was being used on his foot to help him become more mobile.
It Was a long time ago now so I have no way of going back to ask to the exact time or amount he did . This was being done in a regular hospital . It was done in the Naniamo regional hospital . I could try and call the hospital and ask about the therapy and how effective it is . My email is nicoledcarroll@gmail.com .
This was really nice, i know mirror neurons, but not the fact that you can feel things when you got an phantom arm...
Great
excellent talk. This theory/hypothesis is superb!!
@alokbagga
I think I should. It may be a few weeks before I get or locate a copy though.
What a brilliant talk! Fascinating
Spectacular video
recently, parts of my leg were paralyzed.
and now i watch this talk. damn, i could have tried it out. could have been a nice distraction from the other side effect of the nerve damage, extreme pain.
So someone who has lost an arm will feel its loss again and again whenever he sees someone else losing it.. and the one fortunate enough to have his/her arm intact is incapable of feeling the pain of the one who lost it. The irony.
3. Shelter sites for humans have occurred as early as 500,000 years ago altough they became much more widespread with the rise of Homo Sapiens. There is lots of debate about what constitutes shelters, so some definitions push shelter/nesting site creation back a million or more years.
His biggest conjecture is that this explosive change happened due to the rise of this mirror neural system in humans at this time. The problem is that he doesn't provide any paleontological evidence for this changed at this time (setting aside all of the timeline issues above). If he had endocasts of humans 100,000 years ago and 125,000 years ago showing these changes, that would be strong evidence for at least the rise of mirror neurons at that time.
He shows a slide about "Culture and Civilization" he calls the Great Leap Forward, and talks about 5 things that came about and rapidly spread 75,000 to 100,000 years ago:
1. Tool Use
2. Fire
3. Shelter
4. Language
5. Theory of Mind
The problem is not one of these emerged/spread to the whole population during this time period:
Great information :)
WOW . . . science proving consciousness . . .
I wonder what this means in human differentiating in race, Culture, community, religion,...
I'm excited to have class with this guy as my professor later today.
A question:
Ramachandran said that if no receptors sent a data that the hand was not being touched the person would really feel being touched.
What if say, that person lost his hand, why does he not feel that touch?
@thebytegrill ... what I mean is one felt it, the other saw it, yet both observed/empathized an action probably stored in a similar part of the brain. Long way to go no doubt before we call it.
I listened to another TED talk that claimed empathy, cooperation, and other sociological interactions (theory of the mind) are in mammals' dna. I don't know anything, but some of the things he said could come from these higher-level dna functions that were created well before us.
How do we know the neuron isn't firing in response to both your own action and the other persons action because it's percieving both actions as essentially the same-- he suggests here that it fires to *cause* your action but in *response* to someone elses action. But what is that conclusion based on? Perhaps in both cases the neuron is firing in *response* to the action, regardless of whether or not you or someone else does it? Extraordinary claims and all that...
Syncopator Look up di Pellegrino et al. 1992 on observational learning
Ramachandran is good as always. If yall have a chance watch his other stuff on youtube at Beyond Belief 2.0 and mostly the one on UCtelevision- Its long But worth watching.
Is there any overlap in the activity of mirror neurons between watching another person performing and the individual mental practice (without visuals, only in their mind)?
In a similar vein, his slide includes 'Civilization' in the title, and the first true civilizations didn't arise until 6,000-8,000 years ago.
This guy was my prof at UCSD. Always an entertaining lecturer.
this is ballz deep informative! :)
I felt that
4. Language, in terms of what we understand like modern languages, is not known when it arose, but many think these came into being less than 100,000 years ago.
Great post
It seems like science all encompassing!
I'm looking forward to it
would you say it changed the way you think?
Can you post a link, pls? Would like to watch it.
Interesting stuff. The more often neurons fire the more likely they are to fire again (ie have a particular thought). So if this is how our brains work - by mimicking other's actions in our own thought processes, what does that mean for kids watching media generated images of violence etc? Do they have the mimic neurons firing whilst doing so & then are therefore more likely to carry out those action in real life? I wonder...
wow. VSR is awesome..
The latest event was TED India
@IlluminatyKL
Actually, if you keep listening, he says that's exactly what happens.
RRRizzolotti discoverrrrrred the mirrrrrrorrrr nurrrons! :D
Excellent talk!
i've been trying to watch this video for three days now and i cant get it to work.. it this happening to anyone else?
Same here...thought mine was bust went mad trying to fix it...
@damuschka
Do not let what others believe get in the way of what others know.
@ANDR3W1848
Yes!
Anyone watching this amazing lecture in 2021?
Good question; have you found the answer? I'm curious as well.
you ma hero zoth
This guy is awesome.
5. This is very young, and certainly less than 25,000 years. This is the age of the oldest sites that indicate abstract thinking among our ancestors.
This guy is the Carl Sagan of neuroscience. I love him.
Ótimo vídeo! A segunda parte não mostra legenda.
Awesome! 5 stars! I love neuroscience.
i learned about traffic solutions from smart scandinavians :)
that ended way too quickly I WANT MORE!!
He never said anything about directly feeling another's sensations without seeing them. The point is empathy/mirror neurons, not telepathy.
When a person (A) sees another (B) being touched while (A's) arm is anesthetized does not experience the touch. (A) models the touch with mirror neurons and the perception of the model itself is (A's) experience. No need to get spooky.
How does easiness to be manipulated correlate with mirror neurons activity?
What about in cases of Emotional Codependence, Borderline?
great talk.
hate the ad at the end, though... IBM "International Bondage Mongers"
lol jesus christ, his accent made things much better.
Even with a popped collar VS is cool.
