Responses to acoustic stimuli are generated in neurons of nuclei on both sides of the brain stem. In order to determine whether there are electrode positions which can be used to record activity predominantly generated in the neurons of nuclei of one side, the distribution of brain stem responses to acoustic stimuli over the human scalp was investigated. The response is found to be maximum at the vertex, and diminishes gradually toward the nasion, inion and the mastoid process. There are no significant differences between responses to ipsi- and contralateral stimulation. It follows that there are no electrode positions, which can be used to record the activity generated in the neurons of nuclei of one side. There are, however, indications that monolateral pathology of brain stem nuclei may be detectable by comparing responses to stimuli presented on the right, the left and bilaterally.
对声刺激的反应是在脑干两侧核团的神经元中产生的。为了确定是否存在可用于主要记录一侧核团神经元产生的活动的电极位置，研究了人类头皮上脑干对声刺激反应的分布情况。发现反应在头顶处最大，朝着鼻根、枕外隆凸和乳突逐渐减弱。同侧和对侧刺激的反应之间没有显著差异。由此可见，不存在可用于记录一侧核团神经元产生的活动的电极位置。然而，有迹象表明，通过比较对右侧、左侧和双侧呈现的刺激的反应，可能检测到脑干核团的单侧病变。
