"Subthalamic Nucleus" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity.

Der Subthalamus fungiert als Antagonist des Pallidum(Globus pallidus). Der motorikfördernde Teil des Pallidums inhibiert den Nucleus subthalamicus, dieser wiederum regt den motorhemmenden Teil des Pallidum an. Der Nucleus subthalamicus kann somit als Inhibitor der Motorik bezeichnet werden. 3Klinik The subthalamic nucleus is the sole excitatory structure within the basal ganglia.

However, most of Nowadays, the STN is considered to be one of the main regulators of motor function related to the basal ganglia. The role of the STN in the regulation of associative and limbic functions related to the basal ganglia has generally received little attention. 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 cardiovascular motor function. It’s important to note, however, that the functions of the subthalamic nucleus (and basal ganglia as a whole) are not limited to movement. Recent research suggests the subthalamic nucleus may also contribute to cognitive functions like decision-making, attention, and working memory (among others). 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 … En funktionellt sett associerad struktur till basala ganglierna är nucleus subthalamicus, i ventrala thalamus.

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.

3Klinik Nucleus ruber má těsný vztah k regulaci svalového napětí a pohybu, stejně jako substantia nigra, která je nejdůležitějším zdrojem dopaminergních neuronů (produkujících dopamin). Nucleus subthalamicus ( corpus Luysi ) získává nervová vlákna z globus pallidus , odkud vychází i svazek fascilus lenticularis , jehož vlákna končí ve Forelových polích H, H 1 a H 2 .

Parkinson’s disease (PD) is a severely disabling condition for which current drug therapies do not always achieve satisfactory results. Neurosurgeons worldwide have made many attempts to alleviate the symptoms of PD by performing pallidotomy, 1 –4 thalamotomy, 5 or subthalamotomy 6 and high-frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN), globus pallidus internus

Given its central position influencingmany basal ganglia nuclei, it is likely to play an important role in the processing that is performed by the basal ganglia. In this thesis a theoretical analysis of … The subthalamic nucleus is a small lens-shaped nucleus in the brain where it is a part of the basal ganglia system. 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. 2015-11-14 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.

cell nucleus, karyon, nucleus - a part of the cell containing DNA and RNA and responsible for growth and reproduction. subthalamus - the ventral part of the thalamus. The subthalamic nucleus occupies a position in the indirect pathway of basal ganglia circuit, which plays an important role in the movement regulation.

Recently, zo … nucleus (STN), as calculated indirectly from stereotactic atlases or by direct visualization on magnetic resonance imaging (MRI), corresponds to the best functional target.

Subtalamuskärnan och förbindelser genom detta område medverkar i integrationen av kroppens motoriska funktioner. Engelsk definition. Lens-shaped structure on the inner aspect of the INTERNAL CAPSULE. The subthalamic nuclei are small paired structures that are part of the functional basal ganglia.

Among those interconnected nuclei, the sub-thalamic nucleus (STN) plays an important and central role as an excitatory input to the GABA nuclei of the basal ganglia. Se hela listan på hindawi.com subthalamic nucleus: [TA] a circumscript nucleus, shaped like a biconvex lens, located in the ventral part of the subthalamus on the dorsal surface of the peduncular part of the internal capsule immediately rostral to the substantia nigra. The nucleus receives a massive topographic projection from the lateral segment of the globus pallidus and Caudate Nucleus Function. Each of the cerebral hemispheres contains a caudate nucleus, and both are centrally located and close to the basal ganglia.

In this article, Burrows et al compare the motor and limbic function outcomes after short-term stimulation of a deep brain stimulation (DBS) electrode contact in the subthalamic nucleus (STN) versus the zona incerta (ZI) nucleus in 11 patients with Parkinson disease who had previously undergone STN DBS.

Se hela listan på medlexi.de 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. This observation has catalyzed more than a decade of research concentrated on establishing trends and identifying potential mechanisms for these non-motor (executive) functions, are rendered possible by an assembly of subcortical nuclei called the basal ganglia that are connected to the cerebral cortex to form top-down control loops.

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.
