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 have been 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 have been inferred. There prove to be parallels between morphological types of cat monkey ganglion cells.
