recordings of the
auditory system
The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system.
System overview
The outer ear funnels sound vibrations to the eardrum, increasin ...

Auditory evoked potential
An evoked potential or evoked response is an electrical potential in a specific pattern recorded from a specific part of the nervous system, especially the brain, of a human or other animals following presentation of a stimulus such as a light fla ...
s (AEPs). The SVR of a normal human being recorded with surface electrodes can be found at the end of a recorded AEP waveform between the latencies 50-500ms.
Detection of SVR is used to estimate thresholds for hearing pathways.
