Auditory evoked potentials, also known as brainstem evoked potentials, are obtained by stimulating the auditory system with click stimuli. The brain responds to this stimulus by sending out small electrical voltage potentials, which our neural monitoring technologists record through electrodes that are placed on the scalp. By monitoring these neural action potentials between the cochlea (the inner ear cavity that contains nerve endings essential for hearing) and the aural processing centers in the brain, our neural monitoring technologists are able to determine whether or not the patient's he
