WitrynaBasal ganglia. The term "ganglion" refers to the peripheral nervous system. However, in the brain (part of the central nervous system), the "basal ganglia" is a group of nuclei interconnected with the cerebral cortex, thalamus, and brainstem, associated with a variety of functions: motor control, cognition, emotions, and learning. Witryna1 maj 2000 · The basal ganglia influence behaviour by the projections of these output nuclei to the thalamus and thence back to the cortex, or to subcortical ‘premotor’ regions. Recent studies have demonstrated that the organisation of these pathways is more complex than previously suggested. Thus the cortical input to the basal ganglia, in … green hearing protection https://consultingdesign.org

The Basal Ganglia and Adaptive Motor Control Science

WitrynaIn this chapter, we present some recent results on the organization of basal ganglia ‘loops’ with cortical areas in the frontal lobe. Our findings suggest that the primary motor cortex (M1), the supplementary motor area (SMA) and the ventral premotor area (PMv) each project most densely to a topographically distinct region of the caudate/putamen.
