The Split-Brain Phenomenon Revisited: A Single Conscious Agent with Split Perception

The Split Brain Revisited

The Split Brain Revisited Contents

About 35 years ago in Scientific American, I wrote about dramatic new studies of the brain. Three patients who were seeking relief from epilepsy had undergone surgery that severed the corpus callosum--the superhighway of neurons connecting the halv es of the brain. By working with these patients, my colleagues Roger W. Sperry, Joseph E. Bogen, P.J. Vogel and I witnessed what happened when the l...

The Split brain

1. Terminology The term split-brain has several meanings. Applied to the human, it denotes complete sectioning of the corpus callosum, an operation which is usually performed for medically intractable, multifocal epilepsy (Reeves and Roberts, 1995). In the experimental animal, such as the cat or monkey, it usually implies both callosal section and a split optic chiasm; this makes it possible to...

Linear Time Split Decomposition Revisited

Given a family F of subsets of a ground set V , its orthogonal is de ned to be the family of subsets that do not overlap any element of F . Using this tool we revisit the problem of designing a simple linear time algorithm for undirected graph split (also known as 1-join) decomposition.

The problem of split comets revisited

The results fromstudies ofD/Shoemaker–Levy9 and other recent split comets and comet pairs lead to the recognition of fundamental differences between breakupproducts of the tidally and the nontidally split comets and to the conclusive identification of the so-called dissipating comets as secondary nuclei of previously split comets, whose separately arriving principal nuclei had in most cases bee...
