In disorders of the brain involving the auditory pathway, the smoothness of the passage of this electrical impulse gets affected and this abnormality can be picked up by the BERA test. Changes in the function of the neural pathways may occur for many reasons including growths along the nerve, demyelinating disease, stroke, viral infection… BERA is generally used to identify any pathology in the vestibulocochlear nerve or the brainstem. The auditory brainstem response ( ABR) is an auditory evoked potential extracted from ongoing electrical activity in the brain and recorded via electrodes placed on the scalp. (4✔) The inner ear contains the cochlea, which plays an important role in hearing, and the vestibular part, which is involved in maintaining balance. CHIRP BERA which is a very sophisticated form of BERA test is also possible in Vertigo and Deafness Clinic. Brain Stem Evoked Response Audiometry (BERA) The Brain Stem Evoked Response Audiometry (BERA) is an objective test that gives us the approximate average hearing threshold level of the subject.

Test Type : Neurology Tests Preparation : This test is available by appointment only. BERA. When a auditory stimulus (sound) is presented to the ear, an electrical potential is evoked in the cochlea in response to the sound stimulus and this electrical output called ‘action potential’ traverses through the auditory pathway to reach the higher areas in the brain where it is processed and the meaning pertaining to the sound interpreted. History 2 Sohmer and Feinmesser Signal-averaged ECochG studies Jewett and co-workers Identified the short-latency scalp-recorded AEPs as far- field potentials volume-conducted from the brainstem, described the components and their properties Established the Roman numeral labeling of the peaks In Vertigo and Deafness clinic, in addition to click evoked BERA, there are provisions of carrying out Tone Evoked BERA i.e., BERA test with pure tone sounds to objectively evaluate hearing thresholds at different frequencies and also Bone Conduction BERA. An abnormal BERA is an indication for MRI scan. Responses beyond 10 milliseconds are thought to be potentials that arise from thalamus (10-80ms) and cortex (80-500ms) of the brain. Most adults who get hearing tests are asked to wear earphones and listen to short tones that are played at different volumes and pitches into one ear at a time. The hair must be oil-free. The auditory brainstem response (ABR) test tells us how the inner ear, called the cochlea, and the brain pathways for hearing are working. How is Brainstem Evoked Response Audiometry Performed?
