Displaced ganglion cells in the rabbit retina.

Displaced ganglion cells were studied in the rabbit retina after filling them with horseradish peroxidase via injections into the optic nerve. These cells are primarily in areas outside of the visual streak. They are larger than other inner nuclear layer cells and are the size of the smallest neurons in the ganglion cell layer. Large labeled cells (greater than 20 microns) are found only in the ganglion cell layer. These findings further illustrate the wide variability in the size and distribution of displaced ganglion cells in the retinas of different mammals.
