The main circuits of the basal ganglia, a group of nuclei in the brains of vertebrates that act as a cohesive functional unit. Shown here are two coronal slices that have been superimposed to include the involved basal ganglia structures. + and − signs at the point of the arrows indicate respectively whether the pathway is excitatory or inhibitory in effect.
