Histological observations in the normal monkey lateral geniculate nucleus.

As a basis for studies of the histologic effect of visual deprivation, cell section areas were determined in all six laminae from the anterior, central, and posterior regions of both lateral geniculate nuclei (LGN) from a normal macaque monkey. No significant cell size variations existed between the right and left LGN's, between the contiguous parvocellular and magnocellular laminae of the same LGN, and between parvocellular sizes in varous regions of the LGN's. In the magnocellular laminae, cell section areas increased in an anteroposterior direction.
