Abstract

Long-term recordings of dorsal raphe (DRN) activity were obtained from cats chronically implanted with microwires. The continuous time-course of DRN discharge, PGO waves, and muscle tone was quantified across multiple sleep cycles. DRN activity profiles were inversely correlated with PGO waves, biphasically related to muscle tone, and varied with sleep cycle phase. The role of DRN as a putative regulator of behavioral state and/or specific physiological variables is discussed.
