There's a mistake in this video: each hemisphere receives information from the opposite *visual field*, not from the opposite eye.

[veronchiquita]

good observation!

[bkkfrenchie]

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.

@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.

@AnduinX

Because I see no other option!

@purifyz: What makes you think the self is a product of the brain in the first place?

@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

[efherne]

@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!

[efherne]

@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

[purifyz]

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).

[Romera06]

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.
