【摘要】 用直流电阻断方法控制猫隐神经A类或C类纤维冲动的传入,记录杏仁核的单位放电实验结果表明:隐神经的A和C纤维传入冲动可以到达杏仁核,引起其放电增多或减少;A类纤维传入冲动可以明显抑制C类纤维引起的杏仁核诱发放电,而C—AED对A—AED无明显影响,用5HZ刺激(模拟电针)AB纤维,C—AED明显减弱,提示杏仁核有可能与痛觉有关。更多还原

【Abstract】 The amygdala responses to different afferent fibers stimulation were studied on 12 healthy conscious cats.Using direct current cut method, the A or C fibers of saphenous nerve can be stimulated separatly. The experimental results suggested that:Both afferent impulses of the A and C fibers of the saphenous nerve can arrive the amygdala and evoke neuron discharge either to be increased or to be decreased.The afferent impulse of the A fiber of noninjured stimulation may inhibit the C fiber of injured stimulation.更多还原
