Abstract

A method of measuring electrically evoked auditory brainstem responses of a patient or animal body is provided. The method includes surgically implanting an auditory prosthesis having an electrode array, the electrode array positioned either intracochlear or substantially proximate a brainstem of the body. At least one electrode is stimulated in the electrode array. Electrically evoked auditory brainstem responses resulting from said stimulation are recorded using, at least in part, an electrode in the electrode array as a negative electrode, and a positive electrode positioned substantially proximate the vertex of the head of the body.
