Abstract

The effects of stimulus intensity variation on brainstem auditory evoked potentials have been studied on 111 preterm, 36 fullterm neonates and 50 adults. When intensity decreases the lengthening of latencies is greater in preterm neonates. This effect is clearer with wave I than waves III and V and suggests an immaturity of the basal part of the human cochlea in preterm neonates.

摘要

在111名早产儿、36名足月儿新生儿和50名成年人中研究了刺激强度变化对脑干听觉诱发电位的影响。当强度降低时，早产儿潜伏期的延长幅度更大。这种效应在I波比III波和V波时更明显，提示早产儿人类耳蜗基部不成熟。
