By means of implanted multileads electrodes, responses to clicks and prolonged sound stimulations were recorded from the Heschl gyrus of 2 human brains. These responses were strictly localized to this structure. Cortical averaged auditory evoked potentials (c.AEP) to clicks are consistent with scalp averaged auditory evoked potentials (s.AEP). So, Na Pa, Nb, P1, N1, waves have similar latencies and none of them in the s.AEP may be correlated with myogenic potentials (in opposition with the suggestions of Bickford et al. 1964 and Celesia et al. 1968). Increasing the duration of sound stimulation resulted in changes of the response. For a duration longer than 20ms, an "on-response" and an "off-response" were noted. No satisfying physiological explanation of these events is retained despite data obtained with monaural homo and heterolateral stimulations and with variation of tone of sound stimulation.
通过植入多导联电极，从2个大脑的颞横回记录了对滴答声和持续声音刺激的反应。这些反应严格局限于该结构。对滴答声的皮层平均听觉诱发电位（c.AEP）与头皮平均听觉诱发电位（s.AEP）一致。因此，Na、Pa、Nb、P1、N1波具有相似的潜伏期，并且s.AEP中的这些波均与肌源性电位无关（与Bickford等人1964年和Celesia等人1968年的观点相反）。增加声音刺激的持续时间会导致反应发生变化。当持续时间超过20毫秒时，会记录到一个“开启反应”和一个“关闭反应”。尽管通过单耳同侧和异侧刺激以及声音刺激音调变化获得了数据，但对于这些事件仍没有令人满意的生理学解释。
