Consciousness Lost and Found
A Neuropsychological Exploration
It has been discovered that many brain damaged individuals retain intact capacities in what is known as `covert' processing. A blind patient, then, may actually be able to "see" while an amnesiac patient can learn and retain information that he or she does not realize is memory. Weiskrantz uses his research into this phenomenon as a springboard toward a philosophical argument which, combined with the latest brain imaging studies, points the way to specific brain structures which may be involved in conscious awareness.
