Auditory System: Midbrain
From superior olives via
lateral lemniscus to the
inferior colliculus (IC).
Separate path from DCN.
Dorsal IC: auditory, touch
Central Nucleus of IC:
combines LSO, MSO inputs
to 2-D spatial map; passed
on to Superior Colliculus to
match visual map
Medial geniculate body:
Principal nucleus: thalamic
relay of auditory system.
Tonotopic. Other nuclei:
multimodal: visual, touch,
role in plasticity?
