Recordings were made from the auditory nerve near its entrance into the brainstem during neurosurgical operations for cranial nerve disorders. The recorded compound action potentials in response to 2000 Hz tonebursts at 90 dB were characterized by a negative peak with a latency of 3.0 to 3.7 ms. When these compound action potentials were compared with the brainstem evoked potentials (BSEP) recorded from the scalp during the operation or before the operation, it was found that the latency of the main peak of the compound action potential matched the latency of the vertex negative wave located between waves II and III (P2) and the potentials recorded from the nerve were found to match the N2P2N3 complex of the scalp-recorded BSEP. The results indicate that the auditory nerve is the neural generator of the two first peaks in the human BSEP, in contrast to the results of experiments in animals which show that the second peak originates in the cochlear nucleus.
在针对颅神经疾病进行神经外科手术期间,在听神经进入脑干的入口附近进行记录。对90分贝的2000赫兹短纯音做出反应所记录的复合动作电位的特征是有一个潜伏期为3.0至3.7毫秒的负峰。当将这些复合动作电位与手术期间或手术前从头皮记录的脑干诱发电位(BSEP)进行比较时,发现复合动作电位主峰的潜伏期与位于波II和波III之间的顶点负波(P2)的潜伏期相匹配,并且发现从神经记录的电位与头皮记录的BSEP的N2P2N3复合波相匹配。结果表明,听神经是人类BSEP中前两个峰的神经发生器,这与动物实验结果相反,动物实验表明第二个峰起源于蜗神经核。
