A technique has been developed for the recording of the cochlear action potential (electrocochleography) and the brainstem evoked responses to click stimuli by means of earlobe and scalp electrodes with an average response computer. This technique has already proved its usefulness in diagnosis of hearing loss. Since the brainstem responses are generated in the successive brainstem auditory nuclei and since the auditory nuclei and pathways constitute a relatively large volume of brainstem tissue, there is reason to believe that this same technique can also contribute to the diagnosis of brain stem lesions and their localization. When these recordings were made in patients with clinical signs of brain stem involvement, one (or more) of the usual response waves was smaller in amplitude, prolonged in latency, or completely absent. Recording of the cochlear and brainstem evoked potentials thus seems to be a new, simple and rapid tool for the diagnosis of brainstem lesions.
已经开发出一种技术，通过耳垂和头皮电极以及平均反应计算机来记录耳蜗动作电位（电耳蜗图）和对点击刺激的脑干诱发反应。该技术已在听力损失诊断中证明了其有用性。由于脑干反应是在连续的脑干听觉核中产生的，并且由于听觉核和通路构成了相对大量的脑干组织，因此有理由相信同一技术也有助于脑干病变的诊断及其定位。当在有脑干受累临床体征的患者中进行这些记录时，通常的一个（或多个）反应波振幅较小、潜伏期延长或完全缺失。因此，记录耳蜗和脑干诱发电位似乎是一种用于诊断脑干病变的新的、简单且快速的工具。
