Basala ganglier och motoriska system - StuDocu

The subthalamic nucleus (STN) of the basal ganglia is an important element of motor control. This is demonstrated by involuntary movements induced by STN lesions and the successful treatment of Parkinson's disease by STN stimulation. However, it is still unclear how individual STN neurons participate in motor control. Here, we report that the STN has a function in switching from automatic to Se hela listan på hindawi.com part of the basal ganglia , the subthalamic nucleus is found in the diencephalon . It receives input from the striatum and helps to modulate motor behavior. Learn more : Know your brain: Subthalamic nucleus Noun 1.

Subthalamic neurons are intermediate in size between the striatal spiny neurons and the pallidal neurons. 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.

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. 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 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 basal ganglia.

Among the basal ganglia nuclei, the STN has a major function in the motor cortico-basal ganglia-thalamocortical circuit and is a target site for neurosurgical treatment such as parkinsonian patients with long-term motor fluctuations and Among the basal ganglia nuclei, the subthalamic nucleus has a major function in the motor cortico-basal ganglia-thalamo-cortical circuit and is a target site for neurosurgical treatment such as In two studied areas: nucleus subthalamicus (STN) and zona incerta (ZI) three types of neurons were distinguished. Type I, multipolar neurons with quadrangular, triangular or oval perikarya. They have 3-6 primary dendrites which run slightly wavy and spread out in all directions.

7. BACKGROUND AND PURPOSE: Electrical stimulation of the subthalamic nucleus (STN) is an accepted treatment for advanced Parkinson disease (PD). Although procedural details are well established, targeting STN remains problematic because of its variable location and relatively small size (20–30 mm3).
