To reduce the severity of his seizures, Joe had the bridge between his left and right cerebral hemisphers (the corpus callosum) severed. As a result, his left and right brains no longer communicate through that pathway. Here's what happens as a result:

Does he need to have both eyes closed? Could he have kept the right eye open = right brain, and then tried with the left eye open. Might have been even more interesting, since eyes are directly part of the brain.

This is so freaky! I watched this last year in high school Psych and thought it was cool. I just watched a different video today in college Psych and suddenly wanted to find this one. Lo and behold I do, AND it is about Joe and Dr Gazzaniga! The one I just watched was made 13 years after this one. Talk about strangeness! Thanks for posting this!

I got told to search for something like this by my psychology teacher and i can't stop watching them all, they're absolutely fascinating and make Sperry's idea so real, i'm just forever awed by such subjects and experiments.

This is excellent for my A2 studies of Psychology, and of course, when I go on to pursue my degree in this subject. Very insightful, I now understand this much better than before previously watching.

I saw a similar video in my psych class where someone who had seperated hemispheres was really angry with someone. He went to hit the person with his right brain controlled left hand, and his left brain controlled right hand reached over and stopped his left hand from striking the person.I'd like to find that one again!

My daughter saw this in Psychology and we looked here on YouTube until we found it. IT IS AMAZING!!!!

Saw this in Psychology today and it just blew me away... a-m-azing.

Hmmm, I think it's kind of amazing not only how well he draws with his left hand (assuming he is right-handed), but also how well he draws with his eyes closed.

Neat neat neat. My first time seeing actual video of a split-brain patient. I didn't know how they carried out these experiments. I kind of figured they covered one eye or something, and maybe sometimes they do, but this thing of focusing on a point and letting the images seep in makes the point even better. Personal identity and theory of mind are definitely interesting topics.
