PSYB65H3 Chapter Notes - Chapter 1: Traumatic Brain Injury, Peripheral Nervous System, Spinal Cord
Document Summary
*brain organized to create behavior: 1)evolution of brain & behavior in diverse animal species, (2) how brain relates to behavior in normal people (3) how brain changes in people who suffer brain damage or brain abnormalities. *cerebrum: major forebrain structure, consists of 2 virtually identical hemispheres (left & right), responsible for most conscious behavior. *brain: physical object, a living tissue, a body organ. *brainstem: central brain structure responsible for most unconscious behavior. *cerebellum: major brainstem structure specialized for coordinating & learning skilled movements. Large-brained animals, cerebellum may play role in coordinating other mental processes. *neuron: specialized nerve cell engaged in information processing. *spinal cord: part of cns encased within vertebrae. (spinal column) provides most connections between brain & body. *central nervous system : brain & spinal cord, mediate behavior. *peripheral nervous system: body"s neurons located outside cns provides sensory & motor connections to and from cns. *harvey"s brain-in-a-bottle experiment: place brain in bottle separates cns from pns.
