Efferent modulation of hair cell function
... MOC activation alters outer hair cell electromotility—We have previously shown how current shunting caused by MOC efferent activity in a piezoelectric model of the OHC can result in reduced electromotility and thereby alter cochlear amplification [9]. The model results were consistent with and impro ...

Auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
