Arousal and sleep systems

Show Summary Details

Preview

The arousal and sleep systems interact with other functional systems and generate patterns of neural activity which may at times have an asymmetric hemispherical distribution. They utilize many transmitters and employ multiple redundant back-up systems. They are subject to malfunction, as manifested in anxiety states and sleep disorders, and they are very sensitive to centrally-acting drugs. This chapter describes the neurological organization of these systems.
