1) It is hard to learn neuroanatomy of the NS! Lots of divisions and names. We are going to go over it today because: a) to understand how the brain functions, you have to appreciate the different areas, connections between areas b) we will be talking about these different areas during the rest of the course (I’ll mention as we go along), so today’s lecture will give a feel for where these areas are located c) today’s lecture serves as a lesson in how to “categorize” things, which is a big part of any discipline, i.e., learn things in an organized fashion! 2) Need to read the chapter to reinforce, I am going to only show Fgures today. Draw yourself maps/ divisions. 3) ±or the purposes of this course, you’ll mostly be expected to know the main functions of areas. This is not a neuroanatomy course! 4) Still, you will be tested on the neuroanatomy. But you are only expected to remember the names of areas that I mention today .

Basic Subdivisions of the Vertebrate Nervous System 1) CNS vs. PNS (remember, from last week?) Central Nervous System (CNS): Peripheral Nervous System (PNS): the rest 2) Somatic vs. Autonomic (note: book is weird!) A) Somatic : “voluntary” system * Sensory Organs -> spinal cord -> brain Sensory Organs: eyes (vision), ears (audition & vestibular), body surface (somatosensation), tongue (taste), nostrils (smell) * Brain -> spinal cord -> Muscles (“Motor” System)
