Most input comes from collaterals of fibers passing through the thalamic reticular nucleus. The outputs from the primary thalamic reticular nucleus project to dorsal thalamic nuclei, but never to the cerebral cortex. [7] [8] This is the only thalamic nucleus that does not project to the cerebral cortex. Instead it modulates the information from ...
Field H 1, is the thalamic fasciculus, a horizontal white matter tract composed of the ansa lenticularis, lenticular fasciculus, and cerebellothalamic tracts between the subthalamus and the thalamus. These fibers are projections to the ventral anterior and ventral lateral thalamus from the basal ganglia (globus pallidus) and the cerebellum.
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 ...
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 ...
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 ...
The loop involves connections between the cortex, the basal ganglia, the thalamus, and back to the cortex. It is of particular relevance to hyperkinetic and hypokinetic movement disorders , such as Parkinson's disease and Huntington's disease , [ 1 ] as well as to mental disorders of control, such as attention deficit hyperactivity disorder ...
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.
