摘　　要：伤害性刺激猫的腓浅神经诱发体感皮层痛敏细胞放电的非时锁反应(N—TLR)表现为放电间隔变小,电针抑制此反应,使间隔变大,而伤害性刺激诱发的时锁反应(TLR)表现为前一后峰型反应,电针主要抑制后峰.表明N-TLR可以反映总的电针效应,而TLR则反映电针效应的更主要部分,提示观察电针效应不仅要用N-TLR,还要用TLR,后者更为重要.The non-time lock response(N-TLR) of cortical nociceptive unit discharges elicited by the noxious stimulation PN appeared as a decrease of mean value function of interspike interval which was depressed by EA. And the time lock responses (TLR) elicited by the noxious stimulation appeared as an early and late peak response,different peak might reflect different meaning. EA inhibited mainly the lat er peak. It was suggested that N-TLR could reflect the total effect of EA,but TLR could reflect the more important part of the effect. Therefore when studying the effect of EA,not noly the analysis N TLR should be done,but also the analysis of TLR,and the latter might be more important.
