group of cells, constituting several subnuclei, located rostral to the superior colliculus in the “pretectal” area; these cells receive input from retinal ganglion cells (via the optic tract) and project bilaterally to the Edinger-Westphal nucleus; they serve as a relay center for the pupillary light reflex pathway. The group consists of the nucleus pretectalis anterior [TA] (anterior pretectal nucleus [TA]), nucleus pretectalis olivaris [TA] (olivary pretectal nucleus.
