Human retina. Light microscope footage showing a transverse section through rods and cones in the retina of the human eye. Rods (small dots) are long nerve cells which respond to dim light, enabling images to be detected. Cones (larger dark circles) are less numerous shorter cells which detect colour. Rods and cones pass visual signals through the optic nerve to the brain. They occur within the thickness of the retina, rather than on its surface. Magnification unknown. | |
