Auditory Neural Pathway

This diagram gives an overview of the central neural pathway from the cochlea through the brainstem nuclei to the auditory cortex.

  1. auditory nerve (cochlear nerve, acoustic nerve) part of the vestibulocochlear nerve (8th cranial nerve, CN VIII)
  2. cochlear nuclei (dorsal cochlear nucleus, ventral cochlear nucleus)
  3. superior olivary complex (SOC, superior olive)
  4. lateral lemniscus
  5. inferior colliculus
  6. medial geniculate nucleus
  7. auditory cortex

cochlear nuclei

  • ventral cochlear nucleus - (accessory cochlear nucleus) divided into the posteroventral cochlear nucleus (PVCN) and the anteroventral cochlear nucleus (AVCN). Located on ventral aspect of the inferior peduncle.

superior olivary complex

  • lateral superior olive (LSO) - thought to be measure the sound intensity difference between the ears.
  • medial superior olive (MSO) - thought to measure the interaural time difference (ITD), the time difference of arrival of sounds between the ears.
