Part 3 - Phantoms In The Brain (Episode 1)

Episode one of a two-part BBC-4 special program hosted by neurologist V.S. Ramachandran that explains his key findings in certain instances of brain damage that have long been viewed as mere curiosities by the scientific community. This episode focuses on blind-sight, phantom-limbs, anosognosia, and hemispatial neglect.

My apologies for the audio being slightly off, the black bar at the bottom of the video, as well as the temporary video defects; this was the only copy of the video I could find.

This is Part 3 of 5.

This movie makes me seem like I have a neurological disorder that makes audition and vision out of sync.

In the spirt of Ramachandran, I found a solution.

The solution was just to open another window and get the audio from there, starting the audio one second after the video.

It's like when he doesnt register the left side of his brain his world goes back to 2-d thats intriguing

I'm glad there is an example of someone consciously seeing something at 2:04. I never would have understood that without the train.

To say that blind sight is strong evidence to suggest that animals do not possess consciousness is extremely wrong. To be conscious is to be aware. The man WAS conscious of something, even if he wasn't seeing it in the normal sense. Animals are conscious, even if the consciousness is different from what we think of as normal. It is obvious animals feel pain, and they remember faces and names. They will shy away from you if you are repeatedly cruel to them, and they will remember you.

The neglect thing reminds me of the perception filter from Doctor Who. Kind of the same concept.  Who knew that was a real thing?

[Masterofspaces]

@WorldsBestMom1 No, most people who are blind, do not have blind sight. Being blind in the standard sense is where their is damage to the eye, or the optic nerve. This means that there is no visual data what so ever sent to the brain. With regards to blind sight, this is where the eyes still function, but part of the brain has been damaged causing it not to see. But other functions of the brain to do with vision, like motion sensing can remain intact and in the mind see direction, but not 'see'

[WorldsBestMom1]

Do most blind people have blind sight? and if not, then why don't they?

Maybe he's not looking to the left because thats where his wife is :P ZING!
