reticular nucleus of thalamus

(redirected from nucleus reticularis thalami)

re·tic·u·lar nu·cle·us of thal·a·mus

a sheet of fairly large neurons covering the lateral, anterior (ventral), and rostral surfaces of the thalamus; its reticular appearance is caused by the numerous fascicles of the thalamic peduncles that traverse the nucleus The nucleus receives numerous fibers from the cerebral cortex, but it has no cortical projection.
Synonym(s): nucleus reticularis thalami [TA]

The thalamocortical and reciprocal corticothalamic circuits are regulated by the nucleus reticularis thalami, also known as the thalamic reticular nucleus (TRN).
It is likely that birds have some thalamopallial and reciprocal palliothalamic circuits that involve the homologue of the mammalian nucleus reticularis thalami. In birds, this nucleus (previously called the pars dorsalis of the superior reticular nucleus), as in mammals, contains GABAergic neurons (Veenman and Reiner, 1994; Sun et al., 2005), receives an input from the globus pallidus (Medina et al., 1997), and projects to various parts of the dorsal thalamus (Benowitz and Karten, 1976; Mpodozis et al., 1996).
It is for this reason that the brain components serving attention, and particularly the nucleus reticularis thalami, act at a position rather early in the efference copy route.
