Abstract

The pretectal area and superior colliculus play a role in oculomotion.This anatomical approach is preliminary in order to investigate, by electrophysiological and metabolic techniques, particular aspects of motor organization of pretectal area of Macaca fascicularis. We used the valina C14 injected in the eye globe to define the retinal projections on superior colliculus and particularly on pretectum. The radiographs showed clear projections to: nucleus tractus opticus (NTO), nucleus pretectalis posterior (NPP) and nucleus pretectalis olivaris (NPOL). Nucleus pretectalis anterior (Pars compacta and pars reticularis) and anterior pretectal area were not labeled. Accessory optic system appeared labeled, particularly DNT and LTN. Nucleus terminalis medialis did not appear labeled in our radiographs. Moreover, the superior colliculus showed a surprising projection like patches.Supported by Ministero della Pubblica Istruzione (40%).
