Effects of hypothalamic deafferentations on adrenocortical responses in the rat following hippocampal stimulation.

abstract：:1. The somatic location and axonal projections of inhibitory vestibular nucleus neurons activated by the horizontal semicircular canal nerve (HCN) were studied in anesthetized cats. Cats were anesthetized with ketamine hydrochloride and pentobarbital sodium. 2. Intracellular recordings were obtained from 11 neck exten...
