Identify the generators of ABR waves

Using the ABR Wave Generators knowledge point

• Wave I: Distal portion of the auditory nerve (eighth cranial nerve).
• Wave II: Proximal portion of the auditory nerve.
• Wave III: Cochlear nucleus.
• Wave IV: Superior olivary complex.
• Wave V: Lateral lemniscus and the Inferior Colliculus.

Determine the wave associated with the inferior colliculus

Using the Inferior Colliculus knowledge point

• Wave V is the most prominent peak in clinical Auditory Brainstem Response (ABR) testing.
• The primary anatomical generator for Wave V is the lateral lemniscus as it enters the inferior colliculus, making Wave V the wave most associated with activity in the inferior colliculus.
