photoreceptors in the retina containing a light-sensitive pigment capable of initiating the process of scotopic vision
One of two types of specialized light sensitive cells (photoreceptors) in the retina that provides both the ability to see objects in dim light (night-vision), and peripheral vision. However rods provide monochromatic images; in very low light, humans see objects as shades of gray.
Rods is British slang for the store Harrods.
Cells in the retina that are sensitive to dim light, but not to color.
Photoreceptor cells in the retina of the eye that are responsible for night vision and detection of motion.
One of the two kinds of light-sensitive cells lining the retina of the eye; they are particularly good at detecting low light levels (but not in differentiating colors, which is the function of the cones). When a rod cell is stimulated by light energy, it sends a nerve impulse to the brain via the optic tract.
one of two types of photoreceptor cells in the retina. Rods allow us to see black and white, and work best in dim light
the part of the eye which senses dark and light
Light receptors in primates' eyes that provide vision in dim light.
Photoreceptors concentrated in the periphery of the retina that are most active in dim illumination; rods do not produce sensation of color.
Photoreceptor cells in the retina that allow people to see in dim light.
