B.A.E.R (Brainstem Auditory Evoked Response) Genimal also allows one to verify if a dog is affected by serious deafness through the BAER test (audiometry by brain stem’s response). The Auditory Brainstem Response (ABR) is an auditory evoked potential intercepted, from bran’s electric activity, through a series of electrodes that are placed on the scalp.  The deafness is calculated through different waves that are registered 10 milliseconds after an auditory stimulus is first perceived. The waves are labeled with roman numerals. The ABR depends upon exogenous factors. 

The different auditive structures that are responsible for the different kind of waves are: 

-From waves I to waves III: they are generated from the auditory vestibular nerve and inferior.

-Waves IV and V: they are generated from the upper part of the brainstem. 

-More accurate positions: wave I comes from the acoustic nerve fibers’ dendrite, wave II comes from the cochlear nucleus, wave III comes from the superior olivary complex, and waves IV and V are associated with lateral lemniscus. 

You may also execute the official BAER test and an official FSA certificate will be provided.
