Both anodic and cathodic stimulus phases can elicit auditory nerve responses

Evidence

Most cochlear implants (CIs) stimulate the auditory nerve with trains of symmetric biphasic pulses consisting of two phases of opposite polarity. Animal and human studies have shown that both polarities can elicit neural responses. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2268
