Primate Thalamus: More Than Meets an Eye

Anatomical organization of the primate lateral geniculate nucleus.

A recent study shows conclusively that the koniocellular layers of the marmoset dorsal lateral geniculate nucleus have binocularly responsive neurons. This adds a new twist to the traditional view about binocular processing in the primate visual system and raises questions about the role of dorsal lateral geniculate nucleus in early binocular processing.
