The hamster is relatively immature at birth compared with other mammalian species. Because of the amount of maturation that occurs postnatally, the development of the peripheral auditory system of the hamster has generated a great deal of interest. However, indices of the developing functional capabilities of the central auditory system of the hamster are lacking. The following study investigated the ontogeny of brainstem auditory evoked responses (BAERs) to clicks in young hamsters. The general maturational trends noted for other species were found for the hamster. The major peaks of the BAER decrease in latency at the same time relative to birth and at the same rate in the hamster as in the cat and rat. Some maturational events such as the onset of a recordable BAER, appearance of the late peaks and increase in amplitude of the late peaks occur later, relative to birth, in the hamster than in the other species. Development delays in the hamster make it an attractive model for studying postnatal development of the central auditory system.
与其他哺乳动物相比，仓鼠出生时相对不成熟。由于出生后发生的成熟程度，仓鼠外周听觉系统的发育引起了极大的兴趣。然而，目前缺乏仓鼠中枢听觉系统发育功能能力的指标。以下研究调查了幼仓鼠对点击声的脑干听觉诱发电位（BAER）的个体发生。仓鼠呈现出与其他物种相同的总体成熟趋势。BAER的主要峰值在相对于出生的同一时间，以与猫和大鼠相同的速率，潜伏期缩短。一些成熟事件，如可记录的BAER的出现、晚期峰值的出现以及晚期峰值振幅的增加，相对于出生时间，在仓鼠中比在其他物种中发生得更晚。仓鼠的发育延迟使其成为研究中枢听觉系统出生后发育的一个有吸引力的模型。
