title: Thermal responses of ventromedial hypothalamic neurons in vivo and in vitro.
abstract: The ventromedial hypothalamic neurons were recorded in anesthetized rats and in slice preparations. Whereas almost all thermosensitive neurons (27 out of 28) in the slice preparations showed warm sensitivity, cold-responsive neurons were recorded more frequently than warm-responsive ones during preoptic thermal stimulation in anesthetized rats. These results suggest that most cold-responsive neurons excited by preoptic cooling in the anesthetized rats were influenced by synaptic inputs.
