title: Activation of cells of cochlear nucleus by electrical stimulation of lateral hypothalamus.
abstract: Effects of electrical stimulation of the lateral hypothalamus (HS) were examined in 67 cells of the dorsal or ventral cochlear nucleus. Both short latency activity in the 10-20 ms post-stimulus period and late activity in the > 20 ms post-stimulus period were elicited in response to HS. A greater percentage of units exhibited the short latency response in dorsal (89%) than ventral (68%) cochlear nucleus. It was not previously recognized that stimulation of the hypothalamus could elicit increases in spike activity in this auditory relay nucleus. The hypothalamus is known to play a role in visceral-emotional functions, including feeding, fleeing, fighting and reproductive behavior. These results suggest a means by which neural activities supporting these functions could influence acoustic relay transmissions.
