(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.
