Retinal Ganglion Cell Classes in the Old World Monkey: Morphology and Central Projections

Abstract
Labeled ganglion cells were studied in whole-mount retinas of Old World monkeys after electrophoretic injections of horseradish peroxidase into physiologically characterized sites. A number of different morphological classes were identified, each of which has a distinctive pattern of central projection. Since different functional classes of primate retinal ganglion cells also have distinctive patterns of central projection, correspondences between functional and morphological cell types were inferred. There are parallels between morphological types of cat and monkey ganglion cells.
