Born 12 Dec 1939.American neuroscientist and author who studied how the brain enables humans to perform those advanced mental functions that are generally associated with what we call the mind. In over four decades of split-brain research he has advanced understanding of how the brain works, by revealing the separate and highly specialized functions and abilities of each hemisphere. Gazzaniga has focused on how the brain facilitates such higher cognitive functions as remembering, speaking, interpreting, and making judgments. His most recent research uses three-dimensional magnetic resonance images of the brain's surface to compare normal brains with, for example, those having a mental disorders such as schizophrenia.
