The medial terminal nucleus of the monkey: evidence for a 'complete' accessory optic system

The retinal projection to the medial terminal nucleus of the accessory optic system of the monkey was examined in several primate species which had received intraocular injections of [3H]proline or [3H]fucose. These data show that the medial terminal nuclei of the slow loris, marmoset monkey, and squirrel monkey all receive a sparse input from the contralateral retina.
