This study was undertaken to evaluate the analgesic effect of electrical lesion of mesencephalon tractus spinothalamicus and nucleus centralis thalamus with tail stimulation-vocalization test and tailflick latency. The difference of the pain threshold between pre-lesion and post-lesion was significant(P <0. 001 ). The results suggest that electrical lesion of mesencephalon tractus spinothalamicus and nucleus centralis thalamus produce an analgesic effect.
