The principal subdivision of the thalamus into nucleus groups is the trisection of each thalamus (left and right) by a Y-shaped internal medullary lamina. This trisection divides each thalamus into anterior, medial and lateral groups of nuclei. [8] The medial group is subdivided into the medial dorsal nucleus and midline group.
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 .
centromedian nucleus [21] 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 ...
central lateral nucleus; central medial nucleus (not referred to as "centromedial" [2]) paracentral nucleus; posterior (caudal) intralaminar group centromedian nucleus; parafascicular nucleus; Some sources also include a "central dorsal" nucleus.
Lesions of the medial dorsal and anterior nuclei of the thalami and lesions of the mammillary bodies are commonly involved in amnesic syndromes in humans. [ 8 ] Mammillary body atrophy is present in several other conditions, such as colloid cysts in the third ventricle, Alzheimer's disease, schizophrenia, heart failure, and sleep apnea.
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 ...
They also are commonly referred to as laminae medullares thalami or medullary layers of thalamus. The specific layers are: [ 1 ] Lamina medullaris lateralis (external medullary lamina) [ 2 ] — separates ventral and lateral thalamus from the subthalamus and thalamic reticular 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 ...
