BIOC32H3 Lecture Notes - Lecture 8: Substantia Nigra, Cranial Nerves, Reticular Formation
Document Summary
Cerebellum, coordinates voluntary movement, left and right hemisphere, vermis structure in the middle, has deep fissures that help to create other divisions in the cerebellum. Grey matter (outside) and white matter forms a branch like structure and looks like a tree the way the white matter branches in the cerebellum (arbor vitae) Cerebro= pre motor cotex with planning and procedural activities like playing baseball (unconscious because its already known and stored) Spino=regulates muscle tone, coordination of skilled voluntary movement (allowing for improvement in all motor skills) Comparing a predicted sensory consequences to the actual reality ones. Error signals sent back to cerebellum to reevaluate. For example, intention tremor, tremor that only occurs for fine skill difficulty like putting a cap on a pen. Cerebellum in cow is much smaller than human. Cows live in simple environments and have simple movements.
