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