KNES 371 Lecture Notes - Lecture 5: Primary Motor Cortex, Premotor Cortex, Basal Ganglia
Document Summary
Nervous system works all the time and does not work linearly: they will be discussed linearly however, to ease the explanation, the 4 systems influence each other. Front of the head; responsible for putting together a general plan of what to do: projection system. Adds details to the plan of cortex: spinal system. Recruiting muscles at the right time to make the final adjustments to the movement. Pathways to different portions of the brain: allows the consideration of multiple plans to accomplish a movement. Use of memory and different perspectives: quality of plan depends on previous experiences. Provides detailed motor and sensory information to match the goal of the movement and the environmental demands. Determines how big, fast, or strong the movements will be. Relay station; scales the movement patterns of motor impulses. Parkinson"s patients have corrupted basal ganglia; movement is possible (general plan is developed) but the regulation of each parameter is applied incorrectly: cerebellum.
