Abstract
STUDIES of split-brain cats and monkeys demonstrate that each cerebral hemisphere possesses its own perceiving, learning and remembering system, and that each functions independently of the other. Section of the mid-brain commissures also creates two independently functioning systems in the human brain1. The split-brain monkey can process and respond to more information involving bimanual motor sequencing than can control animals with their commissures intact2, and commissurotomy patients perform double voluntary reaction time tasks as fast as they carry out a single reaction3. In man, two verbal messages projected to separate hemispheres are dealt with more efficiently than two messages directed simultaneously to the same hemisphere4, and reaction times are shorter when the information is projected separately to each cerebral hemisphere5.
