cochlea –> auditory nerve –> cochlear nuclei –> superior olives (on both sides) –> lateral lemniscus to the inferior colliculus in the midbrain –> medial geniculate nucleus (thalamus) then to the primary auditory cortex
Primary Auditory pathway: 1. Rostral Medulla contains _______, the mid pons contains ______, the pons-midbrain junction contains ____, the caudal midbrain contains ______, the rostral midbrain contains _____, then finally cerebrum contains the ____.
