Abstract

Electrical stimulation of n. raphe dorsalis in adult cats produced the following effects: (1) suppression of ponto-geniculate-occipital cortex (PGO) waves during REM sleep; (2) mild arousal and orienting responses; and, (3) suppression of feeding in an animal deprived of food for three days. Contrary to these effects, stimulation of n. raphe pontis and magnus triggered the occurrence of PGO waves, produced no arousal and failed to suppress the feeding of food deprived animals. No synchronogenic or sleep-inducing effects were produced by stimulation of any of these raphe nuclei. Stimulation of the midbrain reticular formation produced responses similar to those seen following dorsalis stimulation.
