Modulation Of Electrocochleography Responses By Contralateral Broadband Noise In Young Adults, Riley J. Rickman Jan 2022

Modulation Of Electrocochleography Responses By Contralateral Broadband Noise In Young Adults, Riley J. Rickman

MSU Graduate Theses

While it is known the auditory efferent system contains two distinct subgroups – the medial olivocochlear nucleus (MOC) and the lateral olivocochlear nucleus (LOC) – not much is known regarding the function of the LOC in humans. This study aims to evaluate the effect of activating the lateral olivocochlear (LOC) neurons via contralateral broad band noise (CBBN) on electrocochleography responses. A ten-minute time-blocked paradigm was utilized to evaluate both the slow and fast effect of the LOC neurons. Recordings were obtained at four points within this ten-minute block both with and without the presence of 50 dB SPL CBBN to …
