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.
Deep brain stimulation of the subthalamic nucleus in those with Parkinson's disease has identified the zona incerta as a promising target area for effective therapy. [33] Unlike deep bilateral stimulation of the ventral lateral nucleus such stimulation of the zona incerta improves all aspects of tremor including both the distal and proximal ...
Today these pathways and structures are thought to be central to the pathophysiology of Parkinson's disease, the subthalamic nucleus being one of the major targets for deep brain stimulation. In recognition of Luys discovery Auguste Forel (1848–1931) gave the subthalamic nucleus the name corpus Luysii (Luys' body), a name still sometimes used ...
Subthalamic nucleus (STN) or internal globus pallidus (GPi) The key trial that led to approval is. [74] Further large-scale randomized controlled trials such as, [75] demonstrated the superiority of DBS in the subthalamic nucleus compared to best medical therapy, improving motor function and quality of life.

The subthalamic nucleus is a diencephalic gray matter portion of the basal ganglia, and the only portion of the ganglia that produces an excitatory neurotransmitter, glutamate. The role of the subthalamic nucleus is to stimulate the SNr-GPi complex and it is part of the indirect pathway. The subthalamic nucleus receives inhibitory input from ...
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 basal ganglia is a collective group of structures in the brain. These include the striatum, (composed of the putamen and caudate nucleus), globus pallidus, substantia nigra, and the subthalamic nucleus. Along with other structures, the basal ganglia are part of a neural circuit that is integral to voluntary motor function. [1]
There are some target nuclei for ablative surgery and deep brain stimulation. Those nuclei are the motor thalamus, the globus pallidus, and the subthalamic nucleus. [2] Ablative brain surgery was first introduced by Pierre Flourens (1794–1867), a French physiologist. He removed different parts of the nervous system from animals and observed ...
