i dont think what prof. says is true, because if the seat of self is in left hemisphere, then what happens to people who has it removed? they stop being a person? or became a new one? i think that self is not located in a single part of a brain but is a product of brain working as a whole (even if one of the hemispheres is removed).
@purifyz: Right, I was asking why you see no other option. All we have now is correlation not causation between brain states and consciousness. For example, the view that the brain acts as a regulator and limiter for consciousness actually conflicts with less of what we have observed about mind and brain than the materialist view that the brain produces consciousness.
He is also mistaken about how the brain hemispheres are mirror images of each other. They are asymmetrical in the right anterior frontal lobe, the left posterior occipital lobe, portions of the planum temporale and the sylvian fissure at least! Then again this movie seems pretty old.
there are so many wrong claims in this video. the cerebral hemispheres are not mirror images of each other, with obvious differences in size and shape within convulations, fissures, etc. in addition, this model for the optic tracks only represents the contralateral and not the ipsilateral connections (nasal-retinal vs. temporal-retinal pathways). also, there is no indication of the optic chiasm.
@maleichydrozide .....their personalities are NOT intact. Many are extremely dysfunctional, much like autistics and need excessive therapies(the same types autistic children get) to "reconnect" both sides of the brain. This doesn't always work & some are left permanently disabled. This video says "left brain weaves a plausible story"--if this is the case, then left brain is 'creative.' If right brain sees the world 'literally,' then it would be incapable of being creative--like autistics
@maroom1 ...yes, they do--honestly, if you were going to sum it up--according to this video your 'good' conscious(the honest one) would be a right brain function as it only sees/interprets literal facts. Then left brain would be.....(scary music plays) the little devil in all of us...."weaving" all those plausible stories. Hah! Wait till they discover that left brain is male(testosterone driven) and right brain is female(estrogen/ progesterone driven)....that'll really wow-em!
@maroom1 no it called multiple personality it is psychiatric disorder,people what have it ,act like two or more different persons,Split brain patients havent nothing in common with this
what hand did you use to wank with?;if you use your right hand ;your left hemishere of your brain is the pervert side..hit it with the otherhand to teach it a lesson
hang on the way you said eyes were controlled wasnt quite right. each eye is divided into two halves and the two sides of the brain recieve information from half of each eye.
True, right nasal retina projects on the left hemisphere and right temporal retina projects on the right hemisphere and vice verse. they split on the optic chiasma.
Isn't the job of interpreting ascribed to this mystical integration process in the so-called "right" hemisphere done through the frontal lobes and corpus callosum. Where in the left hemisphere is this "interpreter?" By interpreter do you mean "process" translator? Thanks, Nahulanham
I think he seems to be alluring to Broca's area as an important piece of consciousness which is in the left prefrontal region. Responsible for the creation of language. It's pretty hard to imagine being conscious without having any words to describe our experiences.
Another problem is that he touches on the dreaded "Binding problem." How is it that neural impulses leads to what we experience, there has to be some integration. He seems to offer an explaination, although it seems choppy...
is it just me, or does Dr, Philip Zimbardo creep anyone else out? His videos are great and informative, but that guy gives me the creeps! Stanford Prison Experiment anyone?
It's not "left and right eye". Both eyes have left and right field of vision. The left field of vision, from both eyes, goes to the right side of the brain, and vice versa. This already confuses enough undergrads without your help dude.
the two hemispheres of the brain are not mirror images of each other - what about hemispheric specialisation? e.g. brocca's area on the left in 70-95% of all people?
The brain is a computer, containing connections, or "routers" as you call them, processors, and memory, both random access and long-term. Sections of the brain specialize in certain algorithms, for things like recognizing and formulating speech, fine motor control, breathing, visualization, etc.
a brain cant be that smart man.. there is no algorithm to walk its randomly generated by the way you move your legs tbh.. butt wait a second when your drunk you can't walk in a straight line because some process is disabled which I guess is collision detection or something but then again..... could consicouness just be a sense like people believe there is only 5 senses
SEE, HEAR, FEEL, SMELL, TASTE
but the 6th sense could be talking and the brain it self who knows we might just be a evolutio
The brain is far "smarter" than you think paradoxically. Actually, walking is not a brain process. In fact, it's subroutined in the base of the spinal cord. The brain merly modulates it using our kinesthetic senses as well as our balancing mechanisms in the cerebellum.
There are actually seven senses.
Sight, Hearing, Touch, Smell, Taste, Proprioception and Balance.
Balance from our ears, and proprioception from nerves in our muscles that detect stretching to guide movements.
I can tell you right now.. that the brain cannot be simply explained by science.. hell I was a man of science. Until last week.. when my father got a stroke.. it was not a small stroke but a big one.. he is 61 yrs old and never went to any checkups.. the stroke happened at 1 AM and.. he was not operated until 7 AM.. so he suffered with the stroke for 6 HOURS while hes brain slowly died out.. the doctor said everyone in the world has strokes (microscopic ones) thats how natural deaths happen.
Now the doctor said 1 huge chuck and a little chuck on top died in my fathers brain on the left hemisphere.. he can't move his right arm and most of his right skin/parts have no feelings.. when my bro took our his densures he pieced his lip and he didn't even feel any pain But after 6 hours without any blood/air going to brain and after a week of recovery my father is still who he was.. just talks badly since only 1 side of his lip is working. But it really makes u believe in GOD and always will
Never try to understand everything with science it will make u live a very bad life as god will not forgive you.. he does give you free will thats the best gift you get from god.. but in the end.. god wants you to help him not try/crack to be him.. just live life hope it was suppose to be lived.
"God will not forgive you..." Um...what faith do you belong to? I know of no christian denominations that believe that.
Free will is philisophically debatable. I cite frontal lobotomies as an example. Patients wouldn't control themselves and so their will was taken away at the source - The frontal regions. Thank god these procedures are abandoned now, but it still makes you think about free will.
Never let any one belief blind you from the truths of others.
While your story is interesting, it only makes me think of god in an indirect way. You mentioned that he had lesions in the "top" of the left hemisphere which sounds a lot like part of the primary motor cortex hence his paralysis. He is still who he is since his frontal/prefrontal regions weren't effected.
Yes it is amazing someone can survive that kind of event and it is amazing how God can create such powerful machienery yet only 3 pounds.
yeah its amazing.. and all do you have any good advise for a better recovery?
I was thinking when he got the stroke the best thing i could of done is hit his head.. so the clot would just pass threw.. but it could just as well blocked more arteries those which are more microscopic.
So i have no idea i did nothing let it all up to the doctors.. the nurses do absolutely a very crap job idk.. whatever its all over.
and Yes god is summoned when you pray his old written spells with perfect focus.
um there's more than 5 accepted senses... what about balance, acceleration, pain, temperature, kinesthetic, various internal senses... and those are only ones HUMANS have. There are senses that only certain animals have.
yah your right Radjehuty already said Balance though but those are just combinations of other senses such as sight and feel..
if you were blind and u couldn't feel your legs trust me.. your balance wouldn't exist.. my father has problems walking after stroke because he can't feel feet.
tenoerature is feeling sense.
As for kinesthetic I believe everyone is that.. no one can actually learn by listening to instructors they have to use their hands or see a tutorial to learn. thats dunno if sense
well your balace comes from in ur ears, or somewhere around there like in ur head or something. its a fluid that lets u know if u r tilted or upside down
that would be a obvious explanation but.. why would it go as far as the brain if.. it's near the ear the liquid balancer.. and you drink that goes in the liver/stomach whatever..
meh.. I just gotta read more I guess thanks for trying man.
Haha, images from my left eye isnt consciously processed by my brain (I have an extremely bad case of lazy eye). I wonder what the world would be like for me if this videos interpretation of how the brain interpates images was an accurate model....
Wow - it gets the neuroanatomy wrong. It's a typical undergrad mistake to think that the left eye goes the right brain, and vice versa. But that's incorrect. Information from the left *visual field* goes to the right brain - meaning 1/2 of the information from each eye goes to the right brain, and the other half goes to the left. I'm frankly appalled.
No one - including Gazzaniga - has ever pointed to a specific area of the brain as "The Interpreter", so it's presumably more of a meta-phenomenon than a distinct module.
