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 subthalamic nucleus (STN) is a small lens-shaped nucleus in the brain where it is, from a functional point of view, part of the basal ganglia system. In terms of anatomy, it is the major part of the subthalamus. As suggested by its name, the subthalamic nucleus is located ventral to the thalamus.
Video of relevant anatomy Coronal slices of human brain showing the basal ganglia. White matter is shown in dark gray, gray matter is shown in light gray. Anterior: striatum, globus pallidus (GPe and GPi) Posterior: subthalamic nucleus (STN), substantia nigra (SN) The basal ganglia form a fundamental component of the cerebrum.

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: ...
Original in raster (.png) format - Main circuits of the basal ganglia Original in vector (.svg) format (The brain images at top are imported raster). Reason It explains the circuits of the basal ganglia in an anatomically precise and almost artistic manner, facilitating the understanding of Parkinson's disease and other basal ganglia diseases
