The subthalamic nucleus is a small, oval, section of the subthalamus in the brain, made of gray matter (uninsulated nerve fibers). Functionally, it is part of the basal ganglia system. Since the late 1980s, the neurochemistry and neurophysiology of the subthalamic nucleus have been substantially revised with the demonstration that the subthalamic nucleus is not fundamentally inhibitory but instead provides excitatory glutaminergic inputs to the globus pallidus, and appreciation that the subthalamic nucleus serves an important role in both hyperkinetic and hypokinetic movement disorders. De nucleus subthalamicus is een hersenkern van het centrale zenuwstelsel, die onder de thalamus ligt. Met als functie doorsturen van informatie naar de hoger gelegen hersengebieden.

It is continuous with the thalamic reticular nucleus and receives input from the precentral cortex . The subthalamic nuclei are small paired structures that are part of the functional basal ganglia. They are located ventral to the thalamus, dorsal to the substantia nigra and medial to the internal capsule.
The human subthalamic nucleus (STN) is a massive biconvex lens-shaped nucleus located under the thalamus. Among the basal ganglia nuclei, the STN has a major function in the motor cortico-basal ganglia-thalamocortical circuit and is a target site for neurosurgical treatment such as parkinsonian patients with long-term motor fluctuations and dyskinesia [ 1 ].
