GERO 315g Lecture Notes - Lecture 3: Dura Mater, Pia Mater, Cerebral Cortex
Document Summary
If you divide the brain in half, one half is sensory and one half is motor control. ***calcium: 10*-8 inside the cell, 10*-3 outside the cell. Brain is protected by several layers of tissue, such as the skin, skull, and meninges (a leathery, cushiony layer that holds the cerebral spinal fluid) Gray matter - contains the neurons of the cerebral cortex. White matter - the myelin; axons from the neurons (which connects the neurons to each other) Thalamus: important for distributing sensory info throughout the cerebral cortex - info goes into the thalamus first, then is processed by different areas of the cerebral cortex. Cerebellum: involved in learning and controlling complex movements like riding a bike. Brainstem: important for regulating heart rate, breathing, and eye movements. Ganglia and cerebellum revive input from wide areas of the cerebral cortex and direct their output through the thalamus, and back to more defined regions.
