PS101 Study Guide - Midterm Guide: Slow-Wave Sleep, Occipital Lobe, Prefrontal Cortex
Document Summary
Central nervous- (simple)- brain and spinal cord: receives, interprets and stores info from pns, spinal reflexes, heart beat, breathing. Peripheral nervous system (pns: receiver, send info to cns, 2 types of nerves, somatic nervous system. Motor nerves: to cns to muscles, organs ect: autonomic nervous system (involuntary muscles/movements) Waking: inhibitory- reduced probability of firing (off) ex. Sleeping: in order for neurotransmitter to be accepted, it has to fit like a key and lock. How neurons communicate: synapses: space between neurons that transfer nerve messages with the help of neurotransmitters. Receptor sites: action potential: passing of charge through neurons as the message, neurotransmitters: facilitate either the firing (excitatory) or non firing (inhibitory) of an action potential in the next cell (released from synaptic vesicles) Different types of neurotransmitters: serotonin: sleep, appetite, mood, perception, pain regulation. Depression: dopamine: voluntary movement, pleasure, memory, emotion, learning. Not enough, parkinson"s, schizo: acetylcholine: muscle movement, cognition, emotion, memory.
