NCIt related terms : BRAIN, THALAMUS; dorsal plus ventral thalamus;
NCIt definition : An ovoid mass composed predominantly of gray substance and associated laminae of white
substance. The thalamus is divided into anterior, medial, and lateral parts. The function
of the thalamus is to relay sensory impulses and cerebellar and basal ganglia projections
to the cerebral cortex. The thalamus is positioned within the posterior part of the
diencephalon forming most of each lateral wall of the third ventricle.;
Alternative definition : CDISC: The portion of the diencephalon forming most of each lateral wall of the third
ventricle.; NCI-GLOSS: An area of the brain that helps process information from the senses and
transmit it to other parts of the brain.; UBERON: Subcortical brain region consisting of paired gray matter bodies in the dorsal
diencephalon and forming part of the lateral wall of the third ventricle of the brain.
The thalamus represents the major portion of the diencephalon and is commonly divided
into cellular aggregates known as nuclear groups.(MeSH). The dorsal topographic division
of the interbrain. The macrodissected adult human thalamus was clearly illustrated
by Vesalius in 1543 and the term as defined here was introduced by His in 1893. It
includes the traditional epithalamus, dorsal thalamus, and ventral thalamus of Herrick
(1910, pp. 494, 498). Also see Kuhlenbeck (1927, Ch. 9) and Jones (1985, p. 87).;
