The subthalamic nucleus (STN) is the only excitatory glutamatergic nucleus in the basal ganglia circuitry. It not only is a key node in the classical indirect pathway, but also forms the "hyperdirect" pathway directly connecting the cortex, and even is implicated as a pacemaker for activity of whole basal ganglia.

People with lesions on the subthalamic nucleus have shown increased impulsiveness and behavioral The STN is a small nucleus located below the thalamus; it consists of a relatively homogeneous population of neurons that extend their dendrites in the principal plane of the nucleus. The most distinguishing characteristic of this nucleus is that, unlike the majority of neurons in the basal ganglia (99%), neurons of the STN use glutamate as a neurotransmitter and thus exert excitatory influences on their targets. The subthalamic nucleus, whose neurons contain glutamate and have excitatory effects over neurons of globus pallidus and substantia nigra Zona incerta , located between fields of Forel H 1 and H 2 . It is continuous with the thalamic reticular nucleus and receives input from the precentral cortex . The subthalamic nucleus sends projections to the globus pallidus and the substantia nigra. The neurons of this nucleus use an excitatory neurotransmitter, glutamate. The neurons of the subthalamic nucleus are, in normal motor function, usually inhibited from firing by thalamic override.

The subthalamic nucleus 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. It is also dorsal to the substantia nigra and medial to the internal capsule. It was first described by Jules Bernard Luys in 1865, and the term corpus Luysi or Luys' body is still sometimes used.
