HMB200H1 Study Guide - Comprehensive Midterm Guide: Reflex Arc, Myelin, Synaptogenesis
Document Summary
Tutorial quiz this week: readings and get the textbook. Neuroscience history: overview of neuro-motor pathways, homunculus, unified perception - sensory system overview, neuroplasticity. Course info and admin info given in first few slides. 11pm due date, with a 1h leeway for all assignments (due 12am) Inspired by the st. germain mechanical statues in the 1600s (automata was the name) Stepping on something / interacting with statues will cause something to happen. Focused on reflexive behaviours due to the automata - they were similar. Descartes theorized humans and animals had hydraulic systems, pulleys, etc also. Stimuli vibrate spirits in hollow tubes of brain through ventricles and into muscles. Animal soul/spirits through ventricles causes simple behaviours / reflexes (materalism = fixed) Rational soul in the pineal gland can modify those movement behaviours (spiritualism = can change) Releases at the muscle end plate, attaching to transmitter-sensitve channels. Channels open, allows k and na to cross muscle mem to depol muscle to threshold.
