Age-related changes in auditory evoked potentials are complex and complicated by the confounding effects of gender; concomitant high-frequency hearing sensitivity loss; and, in the case of event-related responses, the nature of the task used to elicit the response. There is a tendency for amplitude to decline and latency to increase, but these trends are not always clear-cut. There is also a tendency for activation patterns to move forward from parietal to frontal areas as age increases. The dichotic listening tool has revealed age-related changes in interaural and interhemispheric asymmetries. These asymmetries seem to be related to loss in the efficiency of interhemispheric transfer via the corpus callosum.
听觉诱发电位的年龄相关变化很复杂,并且受到多种因素的干扰,包括性别;伴随的高频听力敏感度丧失;以及在事件相关反应的情况下,用于引发反应的任务性质。存在波幅下降和潜伏期增加的趋势,但这些趋势并不总是清晰明确的。随着年龄增长,激活模式也有从顶叶区域向前额叶区域转移的趋势。双耳分听工具揭示了双耳和半球间不对称性的年龄相关变化。这些不对称性似乎与通过胼胝体的半球间传递效率下降有关。
