Abstract

Brain-stem auditory evoked potentials (BAEPs) were evaluated over a 39 day period in a patient with a unilateral pontine-midbrain lesion verified by CAT scan and at autopsy. Waves I, II and III were present on the side of lesion, whereas all 5 waves were present on the side opposite the lesion. The findings suggest that the BAEPs may be obtained with only an intact ipsilateral auditory pathway. Crossing fibers in the trapezoid body also appear to make contributions to the normal generation of wave V.

摘要

在一名经计算机断层扫描(CAT)证实并经尸检确诊为单侧脑桥 - 中脑病变的患者中,在39天的时间里对脑干听觉诱发电位(BAEPs)进行了评估。病变侧可引出I、II和III波,而病变对侧可引出全部5个波。这些发现表明,仅在同侧听觉通路完整时才可获得BAEPs。斜方体中的交叉纤维似乎也对V波的正常产生有贡献。
