I've got immense respect for Gazzaniga, but he's got one thing wrong here. He's implicitly equating consciouness with linguistic awareness. It's odd, too, because he's clearly demonstrating conscious awareness of the items in subject's left visual field. I'm guessing he's basically just simplifying things for the audience. Is this from Nova? What year?

Even though everyone in the neuroscience community calls it split-brain, it's really a misnomer, because there remains a lot of communication between the hemispheres via the amygdala and other midbrain structures. There's a lot of neat studies demonstrating this, in particular using highly emotional content.

If you want to go to the beginning though, look up Sperry's groundbreaking split-brain studies from the 60s - for which he won the Nobel Prize.

my favorite generic side-effect story related to this epilepsy treatment is a person reaching into the closet to the get her jacket with her right arm, while her left reaches up towards a hat without her conscious intent.

Guess what happens when you show "split-brain" patients this guy's work?

Berticus- What a dirty trick! LOL. The guy's wiring would start smoking, and BAM!

there may be a link between the congenital version of this, agenesis of the corpus callosum, and being a savant
