All are true about electrocochleography except
Electrodes can be kept over the promontory,EAC or outside,the signals are better as much it is kept close to source. Different waves are cochlear microphonic:produced from outer hair cells action potential is produced by all the nerve fibers Used in diagnosis and monitoring the meiners disease and endolymphatic hydrops
the electrode must be kept close to source of amplitude
actionpotentional is produced by inner hair cells and positive waves
cochlearmicrophonic is produced from the outer hair cells of the cochlea
mostly used in monitoring the meniers disease
