BAER
Also written as: BAER — Brainstem Auditory Evoked Response
A neurophysiological test measuring the electrical activity of the auditory pathway from the eighth cranial nerve to the brainstem.
Full Definition
BAER (Brainstem Auditory Evoked Response) is a diagnostic test that records electrical activity along the auditory pathway from the cochlear nerve through the brainstem in response to acoustic stimuli. The test produces a series of waveforms labeled I through V, each representing neural activity at different anatomical levels. BAER is commonly used to assess hearing function in infants, evaluate brainstem integrity, and monitor neural pathways during surgery. Clinical editors should note that this term is often used interchangeably with ABR (Auditory Brainstem Response) in medical documentation.
Usage
Usage note: Always capitalize as BAER when using the acronym; lowercase when spelling out as brainstem auditory evoked response.
