Words (Names) are remarkably efficient instruments for communication processing. This landmark book presents case histories from the author's own research which illuminate this phenomena from a pathophysiological standpoint. In order to facilitate understanding of the case studies, a hypothetical outline of the central nervous system network processing for the production of propositional communications is presented. An anatomical-physiological model for volitional naming is offered. The following types of memories are discussed: DNA and RNA Memories; Cognitive Memories; Conceptual Memories, Event Memories; Action Memories.
