INFLUENCE OF DORSAL RAPHE NUCLEUS ON ELECTRICAL ACTIVITY OF THE CEREBELLAR PURKINJE CELL IN THE CAT
中缝背核对猫小脑浦肯野细胞电活动的影响

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.
