The subthalamic nucleus is the sole excitatory structure within the basal ganglia. 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 presented.

They are located ventral to the thalamus, dorsal to the substantia nigra and medial to the internal capsule. The subthalamic nucleus receives its main input from the lateral pallidum (external segment of the globus pallidus). We suggest that the subthalamic nucleus the striatum, the main entrance of cortical information (input (STN), a structure endowed with several unique features nucleus), and of the substantia nigra pars reticulata (SNr) and within the basal ganglia, generates a clock allowing the sys- internal pallidum (GPi), which provide the principal output tem to make decisions on ‘what shall I do next?’ However, because of its widespread efferent projections, the subthalamic nucleus exerts its driving effect on most components of the basal ganglia. Its action is mediated not only by the indirect pathway, but by a multitude of mono- and polysynaptic projections that ultimately reach the basal ganglia output cells.

Recently, the mean 3-D Morel-Atlas of the basal ganglia and the thalamus was introduced. It combines information contained in histological data from ten post-mortem brains. 2 days ago 1999-08-01 The basal ganglia system of vertebrates has an extremely complex structure and is composed of many substructures.

3.3); and posthypoxic-ischemic encephalopathy Subthalamic nucleus: a clock inside basal ganglia Liliana Garcia IntroductionBasal ganglia play a central role in the control of motor functions, and pathological alterations of one or more of its components have been implicated in major motor disorders including Parkinson's disease and hemiballism. Parkinson's disease (PD) is characterized by the loss of dopamine (DA) cells in the substantia nigra pars compacta (SNc). The dopamine deficit leads to an increased activity of the output nuclei of the basal ganglia (BG), which could partly be explained by an increase of the excitatory drive from the subthalamic nucleus (STN). http://usmlefasttrack.com/?p=882Basal ganglia, chorea, athetosis, parkinsons disease, intention tremor, limb ataxis, lateral limbs, truncal ataxia, dysarthri De basale ganglia bestaan uit de nucleus caudatus (staartkern), het putamen (schil) en de globus pallidus (bleke kern).

Subthalamic nucleus (STN) neurons have a pivotal role in basal ganglia, as a result of their intrinsic membrane properties, connections within the circuit and glutamatergic nature. “The basal ganglia are the doors that, when unlocked, may release into action functions outside of the Basal ganglia play a central role in the control of mo- basal ganglia” (Llinas, 2000).

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.
