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 essential for initiation of movement (Parent and Hazrati, 1995). [9]
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 ...

Parvocellular reticular nucleus, part of the brain located dorsolateral to the caudal pontine reticular nucleus; Reticulotegmental nucleus, an area within the floor of the midbrain; Thalamic reticular nucleus, part of the ventral thalamus that forms a capsule around the thalamus laterally; Ventral reticular nucleus, a continuation of the ...
Thalamocortical radiations also innervate gustatory and olfactory pathways, as well as pre-frontal motor areas. Visual input from the optic tract is processed by the lateral geniculate nucleus of the thalamus, auditory input in the medial geniculate nucleus, and somatosensory input in the ventral posterior nucleus of the thalamus.
The modulatory functions are primarily found in the rostral sector of the reticular formation and the premotor functions are localized in the neurons in more caudal regions. The reticular formation is divided into three columns: raphe nuclei (median), gigantocellular reticular nuclei (medial zone), and parvocellular reticular nuclei (lateral zone).
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.
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 ...
