The 7 peaks of the Auditory Brainstem Response (ABR) represent neural activity at different points along the auditory pathway. They are numbered I-VII and correspond to the following anatomical locations:
- Wave I: Organ of Corti and extracranial portion of cranial nerve VIII (Auditory Nerve)
- Wave II: Cochlear Nucleus
- Wave III: Superior Olivary Complex
- Wave IV: Lateral Lemniscus
- Wave V: Inferior Colliculus
- Wave VI: Medial Geniculate Body
- Wave VII: Auditory Radiation
These waves are identified and analyzed to assess the function of the auditory pathway, which is crucial for diagnosing hearing loss and neurological disorders. The latencies and amplitudes of these waves are compared to normative data to identify abnormalities.
