How is the mechanical energy transduced into neural energy within the organ of corti?
Cochleic cells are pushed up, bending the stereocilia against the tectorial membrane, causing an action potential
Cochleic cells are pushed up, bending the stereocilia against the basilar membrane, causing an action potential
Hair cells are pushed up, bending the stereocilia against the basilar membrane, causing an action potential
