Auditory nerve-brainstem responses (ABR) to click stimuli were recorded in 26 normal infants when they were neonates and again in the same infants when they were 3 months old. The cochlear microphonic potential was also recorded in several of the neonates. The following response parameters were studied: latency and amplitude of the auditory nerve response, amplitude of the brainstem response elicited from the region of the interior colliculus, the ratio of the amplitudes of these two waves and brainstem transmission time (BTT): the time interval between these two responses. It was found that the auditory nerve response is only slightly prolonged in neonates with respect to adults and shortens by a small amount from birth to the age of 3 months. The latency of the auditory nerve response in neonates is only about 0.3 ms longer than in adults. BTT is longest in neonates and shortens significantly in 3-month-old infants.
对26名正常婴儿在新生儿期和3个月大时进行了短声刺激的听神经-脑干反应（ABR）记录。还对部分新生儿记录了耳蜗微音电位。研究了以下反应参数：听神经反应的潜伏期和波幅、由中脑内丘区域引出的脑干反应波幅、这两个波幅的比值以及脑干传导时间（BTT）：这两个反应之间的时间间隔。结果发现，与成年人相比，新生儿的听神经反应仅稍有延长，从出生到3个月龄时略有缩短。新生儿听神经反应的潜伏期仅比成年人长约0.3毫秒。BTT在新生儿期最长，在3个月大的婴儿中显著缩短。
