| 摘 要： | 本工作旨在研究下丘脑刺激对于刺激尾巴的痛反应及刺激中脑中央灰质(CG)所致的“痛样”反应(叫声)的影响。实验用家猫在浅麻醉下进行。在45次下丘脑刺激中,观察了它对CG所致叫反应的效应,有22次为抑制,6次为易化,17次无作用。在22次下丘脑刺激中,观察了它对尾巴刺激所致叫反应的效应,18次为抑制,4次为无作用。另外在5只具有自发呻呤的猫中,发现下丘脑刺激可以压抑呻呤。以上结果说明下丘脑-中脑统一体在痛调制中的重要作用。

| 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. |
