Most input comes from collaterals of fibers passing through the thalamic reticular nucleus. The outputs from the primary thalamic reticular nucleus project to dorsal thalamic nuclei, but never to the cerebral cortex. [7] [8] This is the only thalamic nucleus that does not project to the cerebral cortex. Instead it modulates the information from ...
This nucleus is located medially to the internal capsule, ventral to the thalamus, and is contiguous with the thalamic reticular nucleus. [6] The nucleus separates the lenticular fasciculus from the thalamic fasciculus (also known as the field H 1 of Forel.) Its cells are very heterogeneous differing widely in their shape and size.
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.
Thalamocortical radiations also innervate gustatory and olfactory pathways, as well as pre-frontal motor areas. Visual input from the optic tract is processed by the lateral geniculate nucleus of the thalamus, auditory input in the medial geniculate nucleus, and somatosensory input in the ventral posterior nucleus of the thalamus.
parafascicular nucleus [22] lateral nuclear group [13] [23] is replaced by posterior region [24] pulvinar [25] anterior pulvinar nucleus [26] lateral pulvinar nucleus [27] medial pulvinar nucleus [28] inferior pulvinar nucleus [29] lateral posterior nucleus [30] belongs to pulvinar; lateral dorsal nucleus [31] (a.k.a. dorsal superficial nucleus ...
In fact, almost all thalamic neurons (with the notable exception of the thalamic reticular nucleus [6]) project to the cerebral cortex, and every region of the cortex so far studied has been found to innervate the thalamus. [7] Each of the thalami may be subdivided into at least 30 nuclei, giving a total of at least 60 for the whole thalamus ...
Parvocellular reticular nucleus, part of the brain located dorsolateral to the caudal pontine reticular nucleus; Reticulotegmental nucleus, an area within the floor of the midbrain; Thalamic reticular nucleus, part of the ventral thalamus that forms a capsule around the thalamus laterally; Ventral reticular nucleus, a continuation of the ...
The subthalamic nucleus (STN) 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.
