PSYA01H3 Chapter Notes - Chapter 3: Amniote, Brainstem, Striatum
Document Summary
Outputs reaction trillions of times of day: neurons cells in the nervous system that communicate with one another to perform information processing tasks, discovery of how neurons function, 1800s scientists turn attention to studying the harder to observe workings of the brain, looked as though it were composed of continuously connected lattice of fine threads. Cell body (soma) coordinates the information processing tasks and keeps the cell alive. largest component: protein synthesis, energy production, and metabolism occur in the soma. s, also contains nucleus chromosomes for dna, also surrounded by a porous cell membrane that allows, two types of extensions from cell membrane that allow for molecules to freely flow in and out of cell. communication: 10 to 50 times as many glial cells as there are neurons serving variety of functions: digests parts of dead neurons, provides physical and nutritional support for neurons, form myelin to help the axon transmit information more efficiently, myelin performs same function for an axon.
