| Abstract: | Abstract: In the crab-eating monkey ( Macaca irus ), the subcortical projection from the retina was studied by means of the autoradiographic method. Retinofugal fibers terminated bilaterally in the suprachiasmatic, pregeniculate, lateral geniculate, olivary, pretectal, lateral terminal and dorsal terminal nuclei and the superior colliculi. In the ipsilateral lateral geniculate nucleus, the retinofugal fibers terminated on laminae 0, 2, 3, and 5; in the contralateral nucleus, they ended in laminae 1, 4, and 6. In the superior colliculi, retinal terminals were aggregated in the stratum griseum superficiale. The ipsilateral suprachiasmatic nucleus showed a heavier labeling than the contralateral nucleus. |
