Neuronal control of the ventromedial nucleus from the periventricular nucleus in the hypothalamic slice of the rat

Abstract

SHIBATA, S., Y. OOMURA AND N. HORI. Neuronal control of the ventromedial nucleus from the periventricular nucleus in the hypothalamic slice of the rat. BRAIN RES. BULL. 8(6) 613-616, 1982.-A neuronal pathway between periventricular nucleus and ventromedial hypothalamus (VMH) was investigated by both anatomical and electrophysiological methods. Horseradish peroxidase (HRP)-labelled clusters were observed in the periventricular nucleus after application of HRP into the VMH. Periventricular nucleus stimulation produced mainly excitation of VMH neurones with a latency of 3 msec. These results suggest that periventricular nucleus sends information in the cerebro-spinal fluid to the VMH. © 1982.
