The nucleus subthalamicus occupied 0,027% of the volume of the hemisphere. 6. The numerical nerve cell densities -- corrected for shrinkage -- were 1970 +/- 145 nerve cells/mm3 for the lateral part and 2910 +/- 310 nerve cells/mm3 for the medial part, this difference of 48 +/- 4% being highly significant.

A basal ganglia nucleus that is found under the thalamus in the base of the diencephalon; it lies between the thalamus and the cerebral peduncle, just rostral to the substantia nigra. The subthalamic nucleus is a satellite of the globus pallidus with which it has reciprocal connections.

They are located ventral to the thalamus, dorsal to the substantia nigra and medial to the internal capsule.

In addition to being involved in the pathophysiology of several neurodegenerative disorders, such as Huntington’s and Parkinson’s disease, the STh is one of the target nuclei for deep brain stimulation. However, most of The number of individual patients showing pathological autonomic test results at 1-year follow-up increased only in the subthalamic nucleus stimulation group. Despite reduced pharmacological treatment and reduced motor disability, bilateral subthalamic nucleus stimulation does not improve cardiovascular autonomic reflex function or protect against development of cardiovascular autonomic failure in Parkinson's disease.

It is not known whether bilateral stimulation of the subthalamic nucleus, performed to improve skeletal motor control in advanced Parkinson's disease, also affects central autonomic regulation of car

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.

If, for example, you are reaching out to pick up a cup of coffee, your brain must not only activate the muscles necessary for the movement, but inhibit those that would counteract the desired movement. Somit übernimmt er eine wichtige bewegungsimpulshemmende Funktion. Eine Schädigung des Nucleus subthalamicus führt zum Krankheitsbild des Ballismus oder bei einseitiger Störung zum Hemiballismus. Elektrische Stimulation des STN mittels implantierter Mikroelektroden kann helfen, die Symptome der Parkinson-Krankheit zu lindern. It has been well documented that deep brain stimulation (DBS) of the subthalamic nucleus (STN) to address some of the disabling motor symptoms of Parkinson’s disease (PD) can evoke unintended effects, especially on non-motor behavior.

The subthalamic nucleus is the large nucleus of the subthalamus, which is anatomically a part of the diencephalon. The subthalamic nucleus itself, however, is functionally considered a part of the basal ganglia. It receives projections from the globus pallidus, the cerebral cortex, the substantia nigra, and the reticular formation of the pons. 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 subthalamus contains nuclei and gray matter like the zona incerta, reticular nucleus, and the perigeniculate nucleus. General functions the subthalamus are responsible for include sexuality, food and water intake and maintenance of hydration, and cardiovascular activity.
