A slight decline in cognitive functions and especially in executive functioning after deep brain stimulation (DBS) of the nucleus subthalamicus (STN) in patients with Parkinson's disease (PD) has been described. This study evaluated baseline parameters that contribute to a deterioration of cognitive functioning after DBS.

Noun 1. subthalamic nucleus - an oval mass of grey matter located in the caudal part of the subthalamus; associated with the striate body cell nucleus The prevalence of all depressive conditions with nucleus subthalamicus stimulation is 11, 6 % and thus it is lower than the prevalence of all depressive conditions in the adult population (15-30 %). The subthalamic nucleus impacts motor control and may also have a role in psychological processes. People with lesions on the subthalamic nucleus have shown increased impulsiveness and behavioral Since the late 1980s, the neurochemistry and neurophysiology of the subthalamic nucleus have been substantially revised with the demonstration that the subthalamic nucleus is not fundamentally inhibitory but instead provides excitatory glutaminergic inputs to the globus pallidus, and appreciation that the subthalamic nucleus serves an important role in both hyperkinetic and hypokinetic movement disorders.

De basala ganglierna har en viktig funktion vid regleringen av våra rörelser. De tar emot ett signalflöde från hjärnbarken och bearbetar det, för att sedan sända det vidare till talamus, varifrån det åter sänds till hjärnbarken.

Er steht afferent und efferent vor allem mit dem Pallidum in Verbindung. Dabei wird er vom motorikfördernden Teil des Pallidums gehemmt und wirkt auf den motorikhemmenden Teil des Pallidums erregend (exzitatorisch, glutamaterg).

The subthalamic nucleus sends projections to the globus pallidus and the substantia nigra. The neurons of this nucleus use an excitatory neurotransmitter, glutamate.
