PS267 Lecture Notes - Lecture 10: Thalamus, Electrical Brain Stimulation, Indirect Pathway Of Movement
Document Summary
Different objects require different actions (e. g. small vs. large coffee cup). Every time you interact with the world there"s 100s of motor programs that are competing with my decision to make them happen. Basal ganglia like gatekeeper chooses one thing out of 100s of motor actions you can do. A lot of predictions going on about why you might want to do a behavior depending on different potential motor actions. Cycle between the motor actions and feedback between other senses (e. g. pick up coffee cup, feel the heat of the coffee cup, see the coffee cup, move it to your lips, etc. Paul sizek single cell recording in monkeys supporting evidence for this hypothesis. Beginning of trial: monkey told which cue it will have, slight activity in delay period when monkey knows stumulus will appear in one of two location.
