Auditory Electrophysiology: Decoding Inner Ear Signals
Introduction and Definition The Summating Potential (SP) is a critical electrophysiological measurement in auditory science, representing a sustained, slowly changing electric potential generated within the cochlea in response to acoustic stimulation. Unlike the rapidly oscillating Cochlear Microphonic (CM) or the transient Auditory Nerve Action Potential (AP), the SP is fundamentally a direct current (DC) shift […]
