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 ...
The subthalamic nucleus, whose neurons contain glutamate and have excitatory effects over neurons of globus pallidus and substantia nigra; Zona incerta, located between fields of Forel H 1 and H 2. It is continuous with the thalamic reticular nucleus and receives input from the precentral cortex.
The tract transmits slow nociceptive/pain information (but thermal, and crude touch information as well) from the spinal cord to reticular formation which in turn relays the information to the thalamus via reticulothalamic fibers as well as to other parts of the brain (as opposed to the spinothalamic tract - the direct pathway of 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 ...
The thalamic fasciculus is formed by the fibers of the ansa lenticularis and the lenticular fasciculus that merge in the field H of Forel. The fibers of this fasciculus then travel to the thalamus and primarily terminate in the ventral anterior nucleus and ventral lateral nucleus . [ 2 ]
Sleep spindles are bursts of neural oscillatory activity that are generated by interplay of the thalamic reticular nucleus (TRN) and other thalamic nuclei during stage 2 NREM sleep in a frequency range of ~11 to 16 Hz (usually 12–14 Hz) with a duration of 0.5 seconds or greater (usually 0.5–1.5 seconds).
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 ...
