PS101 Lecture Notes - Lecture 6: Locus Coeruleus, Reticular Formation, Hindbrain
Document Summary
3 major sections: hindbrain- medulla, cerebellum, pons, midbrain- reticular formation, forebrain- subcortical and cortex (cerebral hemispheres) The hindbrain: basic survival is needed through hindbrain, 3 parts. The hindbrain- medulla: closest to spinal cord, controls vital bodily functions (heartbeat, breathing, blood pressure, circulation, re exes- coughing, swallowing, automatic (can be controlled) The hindbrain- cerebellum: deep convolutions, controls bodily balance and muscular coordination, integrates information from muscles, tendons and joints. The hindbrain- pons: functions as a relay mechanism, assists in control of movement (swallowing, breathing, eyes, face, locus coeruleus- long axon, norepinephrine, attention/arousal. Hindbrain: lower on the nervous system hierarchy, example of the transected cat. Thursday, september 28, 2017: contains neural centres (nuclei, reticular formation (between hind and midbrain) Midbrain: reticular formation regulates attention and alertness (sleep/wake and arousal, contains neural centres that control some motor reactions/movement, substantia nigra- connect with forebrain, neurotransmitter dopamine, fluid movement, stopping movement, parkinson"s.
