Document Summary

3 things to describe about a paper to get 4/4 on quality section. Corticospinal tract: relays info btwn cortex and spinal cord. Primary motor cortex (pmc: e(cid:272)eives i(cid:374)fo a(cid:271)out (cid:271)ody(cid:859)s positio(cid:374) i(cid:374) spa(cid:272)e, (cid:272)a(cid:396)(cid:396)y out goal-directed movements, area 4, generates neural impulses that execute movement. Supplementary motor area (sma: plans and coordinates complex movements, fine motor skills, area 6. Anterior cingulated cortex (acc: choose motor program, action planning, pe value is updated here. Posterior parietal cortex (pcc: sensory and action evaluation (uses external fb) Cerebellum: fine motor movements, relative timing and force, balance and corrdination.

Initiates movement: calculates pes, main ganglia called caudate nucleus, the putamen, the globus pallidus.
