摘　　要：用玻璃微电极记录大鼠丘脑尾核痛兴奋神经元(PEN)放电,观察蛛网膜下腔注射多巴胺(DA)对尾核PEN电活动的影响。结果表明:蛛网膜下腔注射DA可抑制尾核PEN的电活动,使其诱发放电频率减少,潜伏期延长。A microelectrode was introduces into caudate nucleus to record the discharges of pain-excitation neurons (PEN). The influences on electric activities of the PEN were observed after arachnoid space injection of dopamine (DA). The results shows: arachnoid space injection of DA could inhibit electric activities of PEN in caudate nucleus, ie decrease in freguency and increase in latency of the discharges.
