rods and cones

Etymology: AS, rodd + Gk, konos
the light-sensitive cells of the retina. The rods, under the visual purple pigment epithelium, are mainly located around the periphery of the retina. The cones receive color stimuli.

rods and cones

The photoreceptor cells of the retina. They are between the pigment epithelium and the bipolar layer of neurons. The rods contain rhodopsin, which is stimulated by light; the cones contain one of three other photopigments, which are stimulated by various wavelengths of visible light (colors).

The probe aimed for a different set of cells in the retina, the ganglion cells, which, along with the nearby bipolar cells, ferry visual information from the rods and cones to the brain.
In degenerative eye conditions the outermost layer of the retina containing the photosensitive rods and cones wastes away, but the other layers, including the nerve cells which connect to the brain, often remain intact.
