Morphology of cells in the ganglion cell layer during development of the rat retina.
The development of the cells in the ganglion cell layer in the rat retina has been studied from 3 to 30 days of age postnatal by means of Golgi-stained whole-mounted retinae. The retina grows rapidly from birth to ten days of age and then more slowly from 10 to 30 days of age. The different classes of ganglion cell can be clearly recognized by 10 days of age, but type I ganglion cells with a size comparable to those found in the adult rat retina are not seen until thirty days of age. Type II cells may attain their adult size before type I cells do. The growth of the retina and the resulting decrease in cell density in the ganglion cell layer occur with the same time course as the increase in the size of the cell soma and their dendritic fields.
