本文对14例正常足月儿和9例听力正常成人进行了脑干听觉诱发电位的测定。将银-氯化银电极置于鼻根、前额、头顶、骨突上方的每个乳突和第七颈椎（非头侧参考），以研究听觉脑干反应的头皮分布。新生儿和成人人群之间的头皮分布有很大的差异。在同侧乳突，在成人中确定了约2 ms处发生的x波和约3.3 ms处发生的y波;这与新生儿中约3.7 ms处的y波形成对比。似乎有单独的发电机的一些组件在成人与新生儿，和/或作为神经系统的成熟，髓鞘化发生伴随着头皮分布的听觉脑干电位的变化。
The auditory evoked brain stem potential was recorded in 14 normal full-term infants and nine normal-hearing adults. Silver-silver chloride electrodes were placed at nasion, forehead, vertex, each mastoid over the bony prominence, and the seventh cervical vertebra (noncephalic reference) in order to study the scalp distribution of the auditory brain stem response. Large differences in the scalp distribution between the newborn and adult populations were observed. At the ipsilateral mastoid, an x wave occurring at approximately 2 ms and a y wave occurring at approximately 3.3 ms were identified in the adult; this contrasts to a y wave at approximately 3.7 ms in the neonate. It appears that there are either separate generators for some of the components in the adult versus the neonate, and or as the nervous system matures, myelinization occurs with a concomitant change in the scalp distribution of the auditory brain stem potentials.
