ANATOMY 328 Lecture Notes - Lecture 36: Primary Motor Cortex, Adaptive Learning, Dorsolateral Prefrontal Cortex
Document Summary
Wednesday march 14, 2018: the brain part i. Divisions of the brain: telencephalon, cerebrum, diencephalon, anything with thalamus in it, deep in the middle of the brain, mesencephalon, mid brain, metencephalon, pons and cerebellum, myelencephalon, medulla oblongata, has many myelinated axons. Gray matter and white matter: gray matter, cell bodies, dendrites, and unmyelinated axons, cortex: covers the surface of the brain, forms discrete internal clusters called cerebral nuclei, white matter: myelinated axons. In the spinal cord, the gray matter is on the outside and the white matter is on the inside, but this is the opposite of the brain. Cerebrum: contains a large number of neurons needed for complex analytical and integrative functions, contains many sulci and gyri, sulci = spaces, gyri = the parts that stick up more, these are there because of surface area. Corpus callosum: connection between the right and left hemispheres. Corpus callosum and tbi: almost always damaged in tbi and concussion.
