The Split Brain and the Interior Situation of Theories of the Self

Posted by The Situationist Staff on August 26, 2008

The following (5 minute) video demonstrates the effects of split brain surgery where the corpus collusum is severed. The effects are explained by Dr. Michael Gazzaniga.

From Youtube: “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.”

To watch a (3.5 minute) clip from Situationist contributor Phil Zimbardo’s program, Discovering Psychology, in whcih Michael Gazzaniga discusses the essential role of the “interpreter” in creating in each of us a unique sense of self.

Below you can watch an vintage (11 minute) video in which a very young Dr. Gazzaniga goes into detail regarding his early split-brain research on animals and humans (includes a fascinating example of how the right and left hands of a split-brain patient squabble with one another as if hands from two different individuals).
