In fact, almost all thalamic neurons (with the notable exception of the thalamic reticular nucleus [6]) project to the cerebral cortex, and every region of the cortex so far studied has been found to innervate the thalamus. [7] Each of the thalami may be subdivided into at least 30 nuclei, giving a total of at least 60 for the whole thalamus ...

Thalamencephalon (Latin: thalamencephalon), also called thalamic region (regio thalamica) or thalamic complex (complex thalamica) is a complex structure comprising thalamus (in the wider sense of the term thalamus, i.e. dorsal thalamus, or thalamus proper, plus subthalamus, or ventral thalamus) and several adjacent structures: epithalamus and metathalamus.
Thalamic interneurons process sensory information and signal different regions of the thalamic nuclei. These nuclei extend to relay cells, which in turn innervate distinct areas of the cortex via thalamocortical fibers.
In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...
The region separated medially by the medial lamina is the Lateral region (L). Almost separated from the thalamic mass are the Geniculate bodies (G). The remaining isothalamus is made up of the medial region (M, medial to the medial lamina) and posteriorly, with no complete separation in man, of the posterior regio or pulvinar (Pu).
The theory asserts that the thalamic region is the brain area responsible for emotional responses to experienced stimuli. [7] Cannon summarises the observations that serve as the basis for his theory of emotion which claims the thalamic region is the coordinating center for emotional reactions. [14]
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]
