The medial olivocochlear (MOC) pathway modulates basilar membrane motion and auditory nerve activity on both a fast (10-100 ms) and a slow (10-100 s) time scale in guinea pigs. The slow MOC modulation of cochlear activity is postulated to aide in protection against acoustic trauma. However in humans. the existence and functional roles of slow MOC effects remain unexplored. https://www.ealisboa.com/limited-value-AXYS-Valhalla-Pen-must-buy/
