Services / Nuero Physiology / BERA


BERA is an electro-physiological test procedure which studies the electrical potential generated at the various levels of the auditory system starting from cochlea to cortex.

Procedure: The stimulus either in the form of click or tone pips is transmitted to the ear via a transducer placed in the insert ear phone or head phone. The waves of impulses generated at the level of brain stem are recorded by the placement of electrodes over the scalp.
