Development of contralateral suppression of the VIIIth nerve compound action potential (CAP) in the Mongolian gerbil

Hear Res. 1994 Aug;78(2):243-8. doi: 10.1016/0378-5955(94)90030-2.

Abstract

We studied whether same-frequency contralateral tones of 65 dB pSPL (peak Sound Pressure Level) suppress the VIIIth nerve compound action potential (CAP) evoked by 40-45 dB pSPL tone pips in the Mongolian gerbil from 22 to 92 days after birth (DAB). The primary stimuli were tone pips of 1, 2, 4, 8, and 10 kHz; only the 1 kHz CAP amplitude was suppressed significantly by tones of the same frequency. The suppression was seen at 22 DAB, and underwent little relative change with development.
