Abstract:
The present investigation was undertaken to study the effect of hypothalamic stimulation on the pain response elicited by tail stimulation and pain-suggestive response evoked by midbrain stimulation (vocaliz-tion) in lightly anesthetized cat. In 45 hypothalamic stimulations testing its effect on CG-elicited vocalization, 22 inhibited the vocalization response, 6 facilitated it, and 17 showed no effect. In 22 hypothalamic stimu ations testing its effect on tail-elicited vocalizations, 18 inhibited the vocalization, 4 showed no effect Furthermore, in 5 spontaneously groaning cats, hypothalamic stimulations could successively inhibited the groaning. The result indicate that the hypothalamus-mid-brain continum is intimately related with pain modulation.
