EVOKED POTENTIALS
Evoked potential (EP) instruments measure neural synchrony in response to auditory stimuli. In other words, auditory EP tests measure the brain’s response to sound. Auditory EPs can be measured along the entire length of the auditory pathway, from the cochlea to the auditory cortex.
There are several Auditory Evoked Potentials that are used to determine the neural integrity of the auditory system. The clinician defines parameters to isolate the target EP and evaluates the latency and amplitude of the response to make diagnoses and recommendations.
EP testing devices can range from fully clinical to screening. Clinical EP instruments are the most comprehensive devices and include predefined test types, such as ECochG, ABR, MLR, LLR, P300, and ASSR, with the ability to customize collection parameters. Clinical EP instruments allow audiologists to determine neural synchrony and cortical function. Screening ABR devices are simple portable devices that use automated protocols and provide Pass or Refer results.
