Rosenthal is best known for his higher-order-thought (HOT) theory of consciousness. He argues that no mental state is conscious if one is not aware of that state; so a mental state is conscious only if one is aware of oneself as being in that state. And he argues that we are aware of mental states that are conscious by having a thought that one is in that state. These higher-order thoughts are seldom conscious thoughts, and they are distinct from the states they are about. The standard mark in everyday contexts and in experimental psychology that distinguishes conscious mental states is that an individual can report the state; we are unable to report mental states that aren't conscious. Rosenthal argues that it's the higher-order thoughts that accompany conscious states that enable us to make such reports; because we have no such higher-order awareness of mental states that aren't conscious, we can't report them. Rosenthal has also argued that the higher-order-thought theory fits well with recent findings in psychology and neuropsychology (Lau and Rosenthal 2011).

Dr R.W. Sperry of the California Institute of Technology is seeking the answer. Working with him on a series of unique experiment is Dr Michael Gazzaniga. The brain of the course of the enormously complex structure in fact it's kind of redundantly complex we had two cerebral hemispheres in the body we have.


Demonstrates and explains experiments performed by the California Institute of Technology utilizing animals and humans in which the two cerebral hemispheres have been separated surgically. Evaluates results in terms of their contribution to our knowledge of how the brain works

Summary

Explains the revolutionary split - brain operation, performed at the California Institute of Technology, in which the two hemispheres of the brain are separated surgically along the corpus callosum. Demonstrates devices developed to test split - brain subjects to provide insight into the functioning of the brain.
