Midline intralaminar nuclei receive afferents from the brain stem, spinal cord, and cerebellum. Connections with the cerebral cortex and basal nuclei are reciprocal. Afferents from the spinothalamic tract as well as periaqueductal gray are part of a pathway involved in pain processing. [3]
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]
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 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 ...
The rostral thalamus will give rise to the reticular nucleus mainly whereby the caudal thalamus will form the relay thalamus and will be further subdivided in the thalamic nuclei. [ 54 ] In humans, a common genetic variation in the promoter region of the serotonin transporter (the SERT-long and -short allele: 5-HTTLPR ) has been shown to affect ...
In the human brain, the central lateral nucleus is a part of the anterior intralaminar nucleus in the thalamus. [1]: 2 The intralaminar nuclei project to many different regions of the brain, [2] The thalamus acts generally as a relay point for the brain for other areas of the brain to link to. The central lateral nucleus acts in a vital role in ...
(bilaterally via reticulothalamic fibers) thalamus - in turn projects to the cerebral cortex to mediate the conscious perception of noxious stimuli. via central tegmental tract → intralaminar nuclei of thalamus (these are considered a rostral, thalamic extension of the reticular formation) → primary somatosensory cortex
Lamina medullaris lateralis (external medullary lamina) [2] — separates ventral and lateral thalamus from the subthalamus and thalamic reticular nucleus Lamina medullaris medialis (internal medullary lamina) [ 3 ] — positioned between the dorsomedial and ventral nuclei of thalamus, encloses the intralaminar nuclei ( centromedian nucleus ...
