| 摘 要： | 在麻醉并麻痹的猫上观察到:刺激中缝背核(DR)可引起小脑皮层浦肯野细胞(PC)兴奋或抑制(主要是抑制);由被动性腕关节屈伸运动刺激引起的外周本体传入可以增强或减速PC对DR刺激的反应。这些结果表明中缝-小脑5-HT能纤维的传入活动可以调制PC的放电活动,并与外周传入有相互作用。

| Abstract: | In thiopentone-anaesthetized and curarized cats we found that dorsal raphe (DR) stimulation could elicit long latency inhibitory, and in fewer cases, excitatory responses in cerebellar Purkinje cells (PC) , and the peripheral in'puts elicited by passive forepaw flexion-extension movements may enhance or reduce the response of PCs to DR stimulation. The results suggest that the raphe-cerebellar serotonergic fiber may modulate PC's activity and interact with the peripheral input. |
