1. Handouts for 3-D Neuroanatomy We cannot have handouts of the 3-D neuroanatomy (sorry). What I have included Are some images of key structures that will be discussed. In addition we have Provided key talking points to the lecture. - Frank Musiek

2. Key Points Over view of the brain: note optic, olfactory tracts, auditory regions, lobes, Vascular supply –vertebral basilar (B.S.) Cochlear nucleus views Auditory nerve input to cochlear nucleus Inferior colliculus relationship to medial geniculate Internal capsule function and borders Superior temporal plane (define) Heschl’s, Planum Temporale Insula (role in hearing) Views of the corpus callosum (auditory region)

3. Internal Auditory Meatus

4. http://www.geocities.com/medinotes/diagram_auditory_pathways.htm Int. capsule, sub lent. Inferior colliculus Aud. cortex MGB Dorsal coch. nuc. Ventral coch. nuc. Lat. lemniscus SOC Acous. stria Aud. nerve Spiril gang. Brainstem & cerebral auditory tracts
