title: Responses of preoptic neurons to stimulation of caudal and rostral brain stem reticular structures.
abstract: Effect of stimulation (1 Hz) of rostral and caudal brain stem reticular formation was studied on 41 neurons of preoptic area in encéphale isolé cats. Primary excitation was seen on almost all the 25 neurons influenced by stimulation of either of the areas. Many of these influenced neurons received inputs from both areas and showed poststimulatory oscillations in excitability. The two brain stem reticular structures, which have antagonistic influence on cortical EEG, cortical and subcortical neuronal activity, had identical influence on preoptic area neurons when stimulated at 1 Hz.
