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 […]
Introduction and Definition of Sensory Evoked Potential (SEP) The Sensory Evoked Potential, frequently abbreviated as SEP, represents a specialized class of electrical brain activity recorded in response to external sensory stimulation. Fundamentally, an SEP is a neurophysiological measure captured by highly sensitive recording electrodes precisely affixed to a person’s scalp, reflecting the brain’s immediate electrical […]
Introduction to Auditory Evoked Potential The Auditory Evoked Potential (AEP) refers to the naturally produced electrical response generated by the nervous system in response to an acoustic stimulus. This physiological phenomenon represents the synchronous firing of large populations of neurons along the entire auditory pathway, starting from the cochlea and extending to the cerebral cortex. […]
