Outer hair cell is dancing in response to sound stimulus
OUTER HAIR CELLS can contract, and therefore act as motor units that amplify the movement of the basilar membrane in response to a stimulus - some of this added energy is transmitted back through the middle ear, where it can be recorded as an otoacoustic emission think of a swing: if a person sitting on a swing (basilar membrane) pumps his legs (OHC), the amplitude of the swing motion is increased in response to a push (sound stimulus)
