The Neurocognitive Processes That Support Motor Control^a

Process	Function in Motor Control	Anatomic Locus
Strategic	Goal or action selection	Various regions in frontal cortex
	Switching to more optimal actions
	Inhibition of unwanted tendencies
Perceptual motor integration	Selection of spatial targets	Parietal cortex
	Transfer to egocentric space	Premotor cortex
Sequencing	Ordering of movements in the correct sequence	Basal ganglia and supplementary motor cortex
Timing and force control	Adjustment of time and force of movements or muscle commands	Cerebellum
Dynamic	Innervating muscles	Motor cortex
Monitoring	Evaluating outcome	Medial frontal cortex
