The wave ' V ' in BERA represents activity in which of the following ?
(A) Lateral lemniscus (B) Superior olivary complex (C) Cochlear nerve (D) Cochlear nucleus
(A) The wave 'V' in BERA represents activity in lateral lemniscus.Auditory brainstem response (ABR):Is used to elicit brainstem responses to auditory stimulation by clicks or tone bursts.It is a non-invasive technique to find the integrity of central auditory pathways through the VIIIth nerve, pons and midbrain.The first, third and fifth waves are most stable and are used in measurements.Wave V Generation of wave V reflects the activity of multiple anatomic auditory structures. The sharp positive peak of wave V arises mainly from the lateral lemniscus, following slow negative wave represents the dendritic potential in the inferior colliculus.
