Abstract
The optic radiations (OR) is the major white matter tract responsible for relaying visual information to primary visual cortex (V1) (Swienton & Thomas, 2014). We characterized the development of the OR in infant rhesus macaques and infant humans through evaluation of diffusion tensor imaging. We find that for both macaque and human OR there is no evidence for differences in OR volume between the left and right hemispheres. Further, we find that the OR volume compared to whole-brain volume was similar between the two species. We conclude that the development and the volume of the OR is highly conserved between macaques and humans.
