Document Summary

Subcortical structure located at the base of the forebrain. Globus pallidus: internal segment which (major output nucleus) and external segment (intrinsic circuitry) Substantia nigra: pars compacta (dopamine production) and pars reticulate (major output nucleus) Arise from the globus pallidus (gpi) and the substantia nigra pars reticulate (snpr) Doral premotor area (pmd): planning/ selection of goal directed voluntary movements. Hand shape for grasping, aligning the hand and moth. Supplementary motor area: planning/selecting sequences of self- initiated voluntary actions. Prefrontal cortex (pfc): selection and planning voluntary motor actions. Posterior parietal cortex (ppc): somatosensory and visual feedback for selection and guidance of motor actions. Involved in controlling reflexive eye movements following rapid changes in head orientation. [both transmit information about head orientation from receptors in the inner ear] Primary motor cortex: selection, planning and initiation of a specific motor action amongst many possible alternatives. Posterior parietal cortex: influence the processing and integration of somatosensory and visual feedback during ongoing actions.
