WebSection through the retina, showing types of neurones Photoreceptors labelled 1-6 are rods, 7 & 8 are cones Rod cells 1 and 2 share the same ganglion cell and neurone, so light falling on both of these only registers as a single spot. Rod cell 3 has a separate neurone so when light falls on 2 and 3, two separate spots may be seen. WebRod cells, or rods, are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor, cone cells.
