From Wikipedia: “The corpus callosum is a structure of the mammalian brain in the longitudinal fissure that connects the left and right cerebral hemispheres. It facilitates communication between the two hemispheres. It is the largest white matter structure in the brain, consisting of 200-250 million contralateral axonal projections. It is a wide, flat bundle of axons beneath the cortex. Much of the inter-hemispheric communication in the brain is conducted across the corpus callosum.”
Curious things happen when this inter-hemispheric communication is interrupted…
Summary: A scientist explains split-brain (commissurotomy) patients, whose corpus callosum has been cut so that the two hemispheres work separately. The speaker describes experiments in which the right hemisphere, which cannot speak, answers yes or no questions by pointing, and reports a patient whose two hemispheres gave different answers when asked about belief in God. The talk is not by Andy.
