This traditional list does not accord strictly with human thalamic anatomy. Nuclear groups of the thalamus include: anterior nuclear group [1] (anteroventral, [2] anterodorsal, [3] anteromedial [4]) medial nuclear group (medial dorsal nucleus, [5] a.k.a. dorsomedial) parvocellular part [6] (a.k.a. parvicellular part) magnocellular part [7]
The thalamus has multiple functions, and is generally believed to act as a relay station, or hub, relaying information between different subcortical areas and the cerebral cortex. [29] In particular, every sensory system (with the exception of the olfactory system ) includes a thalamic nucleus that receives sensory signals and sends them to the ...
The medial dorsal nucleus (or mediodorsal nucleus of thalamus, dorsomedial nucleus, dorsal medial nucleus, or medial nucleus group) is a large nucleus in the thalamus. [ 1 ] [ 2 ] It is separated from the other thalamic nuclei by the internal medullary lamina .
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 ...
Instead it modulates the information from other nuclei in the thalamus. Its function is modulatory on signals going through the thalamus (and the reticular nucleus). The thalamic reticular nucleus receives massive projections from the external segment of the globus pallidus , thought to play a part in disinhibition of thalamic cells, which is ...
The thalamus supplies all parts of the neocortex with afferents. [3] The main thalamocortical fibers extend from different nuclei of the thalamus and project to the visual cortex, somatosensory (and associated sensori-motor) cortex, and the auditory cortex in the brain. Thalamocortical radiations also innervate gustatory and olfactory pathways ...
In the anatomy of the brain, the centromedian nucleus, also known as the centrum medianum, (CM or Cm-Pf) is a nucleus in the posterior group of the intralaminar thalamic nuclei (ITN) in the thalamus. (This must not be confused with the central medial nucleus, which is in the anterior group of the ITN.) There are two centromedian nuclei arranged ...
The ventral posterolateral nucleus (VPL) is one of the subdivisions of the ventral posterior nucleus in the ventral nuclear group of the thalamus. [1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the dorsal column-medial lemniscus pathway) which synapse with the third-order neurons in the nucleus.
