Waking and the Reticular Activating System in Health and Disease provides a comprehensive overview on the "activating" properties of the RAS. In health, the RAS provides the basis against which we assess the external world, and in disease it distorts that world and shatters our self-image. This book describes the physiology of each process, how it is disturbed in each disorder, and what the most appropriate treatment should be. Dr. Garcia-Rill, along with contributions from leading specialists, discusses the understanding of the RAS as a system not only modulating waking, but also in charge of survival mechanisms such as fight vs flight responses and reflexes. The full spectrum of these functions helps explain the complexity of symptoms evident in such disorders as disparate as schizophrenia and Parkinson's disease. The book reviews the mechanisms that control waking and arousal, and especially how those mechanisms malfunction in certain neurological and psychiatric disorders.
