after several steps of processing, basal ganglia output is directed to the thalamus, which in turn projects back to the cerebral cortex thus, the overall function of the basal ganglia is …

Major structures are thalamus, hypothalamus, basal ganglia and limbic system. Structure Description Function Thalamus Consists of collection of nerve nuclei Main function = act as relay station for sensory info – thus receives sensory info and then it sends info to the appropriate structures or areas o the cortex Hypothalamus Below the thalamus

Lecture 28 -- Basal Ganglia -- Eidelberg. General points. The cortical motor areas receive subcortical input from multiple sources but the most substantial source is from various portions of the ventrolateral thalamus. This region provides the major route by which the output of the cerebellum and basal ganglia gain access to the frontal lobe.

Thus, basal ganglia output suppresses excitation in the cerebral cortex via the thalamus and in brain stem pre-motor neurons. In other words, the basal ganglia output normally suppresses actions, thoughts and emotions. To make a particular action occur, part of the output of the basal ganglia …
Anatomy of the Basal Ganglia
Model of Basal Ganglia Function. One hypothesis suggests that the basal ganglia automatically execute learned movement sequences. This theory is supported by the fact that patients with PD have difficulty coordinating complex movements of several body parts in sequence, such as when writing.

It is based on our understanding of the parts of the basal ganglia that are important in movement control. Follow the direct and indirect paths. Consider this circuitry in a broad context by reviewing the specific cortical, striatal, pallidal, and thalamic regions that are important in the: 1) limb motor function, 2) oculomotor control, 3 ...

Paralell Circuits, Linking Cortex, Basal Ganglia and Thalamus. The effects exerted by the basal ganglia on other parts of the nervous system are mediated primarily by efferent fibers from the pallidum and substantia nigra. These nuclei receive their main efferents from the striatum.
