摘要
摘要 本实验以30只清醒制动的家兔为对象,观察刺激前额
    叶对杏仁核痛单位电活动的影响及其可能的作用机制。采用玻璃微
    电极通过细胞外记录杏仁核(A_(2-4)L_(4-7)H_(15-18))的神经元放电。共观察254
    个杏仁核神经元放电活动,114为痛单位,53个(46.49%)为痛兴奋单
    位(PEN),61个(53.51%)为痛抑制单位(PIN)。电刺激PFC能使杏仁
    核痛单位(90.35%)的自发放电活动产生改变:大部分神经元对刺
    激PFC引起的反应与伤害性刺激引起的反应形式相同,表现为均增频
    或均减频。有30个(56.60%)PEN的自发放电增加(P<0.05),35个
    (57.38%)PIN的自发放电减少(P<0.05);少部分对两者反应形式
    相反,包括18个(33.96%)的PEN的自发放电减少,20个(32.79%)
    PIN的自发放电增加。电刺激PFC对(51.25%)杏仁核痛单位的伤害
    性反应以加强为主,使PEN的兴奋过程加强和PIN的抑制过程加强;
    也可以抑制部分(33.75%)杏仁核痛单位的伤害性反应,即PEN的兴奋
    过程减弱和PIN的抑制过程减弱。这两种刺激PFC对杏仁核痛单位伤
    害性反应的效应分别在侧脑室注射氟哌啶醇、纳络酮后被削弱,这
    两组的P值分别为(n=15,P<0.001)和(n=13,P<0.001)。而生理盐水
    对照组(n=10,P>0.1)无统计学意义。实验结果表明:PFC可影响杏仁
    核痛单位的放电活动:PFC可通过杏仁核参与伤害性反应的调制;多
    巴胺、阿片肽可能参与这一过程的实现。
The purpose of the work was to observe the effects of
     stimulating the prefrontal cortex on pain-related neurons of amygdala and
     preliminary explore of probable mechanism in 30 conscious immobilized
     rabbits. Unit discharges of amygdala(A2~L4.7H15.,8) were recorded
     extracellularly with glass microelectrode .The electric activities of 254
     neurons in the amygdala were observed .There were 114 neurons (pain
     units )responding to peripheral noxious stimulation, including 53(46.49%)
     pain excitatory units (PEN) and 61(53.51%) pain inhibitory units
     (PIN).The nociceptive responses of 90.3 5% pain units also responsed to
     the PFC stimulation. Of these neurons, 30 PEN (P<0.05) and 35 PIN
     (P<0.05) altered their spontaneous discharges in responded to noxious
     stimulation and PFC stimulation in a similar manner . The remainder (18
     PEN and 20 PIN )opposited manners. PFC stimulation could alter the
     responses of amygdala neurons to noxious stimulation. PFC stimulation
     could enhance or reduce noxious-evoked discharge in amygdala
     neurons(5 1.25%) which altered their electric discharges in responded to
     noxious stimulation and PFC stimulation in a similar manner . PFC
     stimulation could reduce noxious-evoked discharge in amygdala
     neurons(33.75%) which altered their electric discharges in opposite
     manners.The two effects of electric stimulating the PFC on noxious-
     evoked discharge in amygdala neuron were attenuated after haloperidol
     (n45,P<0.001) or naloxone (n13, P<0.001) was injected into lateral
     ventricle. And in the saline control group,there was no statistical
     difference(n10,P>0. 1).The experiment results showed that the PFC can
     influence the electric activities of pain units in amygdala. Dopamine and
     Opioid peptides may take part in modulation of the PFC to the nociceptive
     responses of pain units in amygdala.
