Document Summary
Lecture on nov. 10 - motor (eye movements): Review cerebellum: 4 loops (2 major loops divided in two) = mossy bers short circuit onto deep cerebellar nuclei. Granule cell spread out on tons of purkinje cells (summarize) gabaergic inhibitory connection back onto deep cerebellar nuclei: time delay loop! = 1/2 is going to red nucleus inferior olive climbing ber purkinje cell negative connection back onto deep cerebellar nuclei. Eye movements: five different ways of controlling eye movements: 1. saccades cortex; superior colliculus (fovea and scanning a target: in between moments, you are essentially blind! 3. smooth pursuit ability to grab a target and track it; upper visual, slow, and physics: most sophisticated computation our brains do compute and position objects in visual. Eld: taken a single frame and computed a trajectory so you can pin-point future position (waits and takes a snapshot; repeat, starts at around age 3!
