English: Connection diagram of the basal ganglia. Glutamatergic pathways are red, dopaminergic pathways are magenta and GABAergic pathways are blue. GPe = Globus Pallidus external; GPi = Globus Pallidus internal; STN = SubThalamic Nucleus; SNpr = Pars Reticulata portion of Substantia Nigra; SNpc = Pars Compacta portion of Substantia Nigra
English: Circuits of the basal ganglia. Picture shows 2 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.
The direct pathway, sometimes known as the direct pathway of movement, is a neural pathway within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement. [1] It works in conjunction with the indirect pathway.
Globus pallidus line was pointing to the wrong object and removed inaccurate label (the basal ganglia is all of the pink and purple except the tip) 15:06, 2 September 2019: 490 × 330 (39 KB) Slashme: Correct spelling: "globus pallides" → "globus pallidus" 14:22, 7 May 2009: 490 × 330 (39 KB) Madhero88: Another correction: 13:45, 7 May 2009: ...
The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.

Anatomical overview of the main circuits of the basal ganglia. Subthalamic nucleus is shown in red. Picture shows 2 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.
