Document Summary
Stage #1: ready: structures: association areas of the cortex, pfc and bg. Pfc is located towards the front of the brain near the cortex. Bg: basal ganglia: role: goals and strategy of the movement. Define the highly cognitive goals and strategy of the movement. Stage #2: set: structures: m1, pmc, sma, and cb. Cb: cerebellum: role: sequence of muscle contractions (space, time) to achieve the goal. Stage #3: go: structures: bs and sc. Sc: spinal cord: role: activation of the motor neurons to generate the sequence of muscle contractions (including postural adjustments) to achieve the goal. Multisensory sensory integration: structures: association areas of the cortex: pc, role: integration of various sensory information: mental image of the body. High level planning: structures: pfc, bg, role: pfc accesses this image to (cid:498)do its work(cid:499) control) Executive functions (includes many things, including inhibitory. Vestibular nuclei will provide information about the state of the body.
