摘　　要：目的　采用直流电刺激家兔茎乳孔以外的面神经周围段的方法 ,研究并观察能否在实验动物的头皮记录出面神经诱发电位。方法　选 15只健康成年家兔 ,解剖茎乳孔以远的面神经周围段 5mm ,以直流电刺激 ,头顶圆盘电极记录。结果　从家兔头顶均记录出了含P0 和P1 两种成份的清晰的面神经诱发电位。结论　可从家兔的头顶上记录出清晰可辨的面神经诱发电位 ,其两种成份分别起源于面神经本身及其所支配的面肌。Objective To investigate the possibility of recording the Antidromic Nerve Evoked Potentials(ANEP) from rabbit′s scalp. Methods With electrical stimulation of peripheral segment of facial nerve outside the stylomastoid foramen in rabbits, recordings were made on scalp using low impedance silver disc electrode. Results At the vertex, clear ANEPs composed of two waves, wave P 1 and P 0, were recorded in all experimental animals. Conclusion The study shows that ANEPs can be recorded on rabbits′ scalp. The ANEPs have two waves, P 1 and P 0. The sources of the responses are from facial nerve and its muscle respectively.
