听性脑干负相慢反应是指给声刺激后在10ms左右时记录的一颅顶负相电位。它由ABR波V下降支延伸形成的一个负相波。用短声(click)刺激,强度为30dB SL时,听性脑干负相慢反应的潜伏期约为10ms,故称之为慢负10(Slow Nagative10,SN10)。1971年Jewett和Williston在研究ABR过程中,在1.6～100Hz滤波条件下,首次观察到本电位。1979年Davis等正式命名为SN10。尽管众多的学者已经接受 Negative brain stem response is slow response to the acoustic stimulation recorded at about 10ms negative phase potential of a top of the skull. It consists of ABR wave V descending branch formed a negative phase wave. When stimulated with a click, the latency of the slow response of the brainstem to the auditory brainstem is about 10 ms when the intensity is 30 dB SL, so it is called Slow Nagative10 (SN10). Jewett and Williston in 1971 in the study of ABR process, the first filter to see the potential of 1.6 ~ 100Hz. Davis and other formally named SN10 in 1979. Although many scholars have accepted
