Abstract

Neurones in nucleus raphe magnus (NRM) and the adjacent reticular formation with rostral projections were identified by their antidromic responses to stimulation at periventricular forebrain sites in rats and cats. In subsequent experiments, the effects of stimulation in the midline of the ventral medulla were tested on the activities of periventricular forebrain neurones. Taken together, the results of these experiments suggest that a direct inhibitory projection may exist from NRM to ventromedial forebrain structures including the anterior hypothalamus/preoptic region in rats in addition to polysynaptic pathways which mediate both excitations and inhibitions in rats and cats.
