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.
