The Role of the Basal Ganglia in Movement

Main circuits of the basal ganglia

Main circuits of the basal ganglia

This diagram shows the main circuits of the basal ganglia. Two coronal slices have been superimposed to include the involved basal ganglia structures. The + and - signs at the point of the arrows indicate whether the pathway is excitatory or inhibitory, respectively, in effect. Green arrows refer to excitatory glutamatergic pathways, red arrows refer to inhibitory GABAergic pathways and turquoise arrows refer to dopaminergic pathways that are excitatory on the direct pathway and inhibitory on the indirect pathway.
