layer of rods and cones

The injected human cells seemed to behave as retinal cells should, and the treated rats retained some six layers of rods and cones in their retinas, as much as half the normal value.

The stem-like cone granules, fewer in number than the rod granules, are placed close to the membrana limitans externa, through which they are continuous with the cones of the layer of rods and cones.

The elements composing the Layer of Rods and Cones (Jacob's membrane) in the retina of the eye are of two kinds, rod cells and cone cells, the former being much more numerous than the latter except in the macula lutea.
