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 ...
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus; paratenial nucleus (nucleus parataenialis) nucleus reuniens (also known as the ...
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.
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 ...
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 ...
These fibers are projections to the ventral anterior and ventral lateral thalamus from the basal ganglia (globus pallidus) and the cerebellum. H 1 is separated from H 2 by the zona incerta. Field H 2 (synonymous with lenticular fasciculus) is also made up of projections from the pallidum to the thalamus, but these course the subthalamic nucleus ...
The pulvinar is usually grouped as one of the lateral thalamic nuclei in rodents and carnivores, and stands as an independent complex in primates. Pulvinar acts as an association nucleus that, along with medial dorsal nucleus, connected with parietal, occipital, and temporal lobes, but the function is largely unknown. No distinctive syndrome or ...
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.
