one of the two photoreceptors in the vertebrate eye that is responsible for night vision and black and white vision.

A rod-shaped photoreceptor in the retina of the eye that responds to low levels of illumination. Rods are located only outside of the fovea.

Light-sensitive, specialized retinal receptor cell that works at low light levels for night vision. A normal retina contains 150 million rods.

The cells in the retina that are involved with black and white or dim (night) vision.

Part of the photoreceptors that are primarily responsible for peripheral and night vision and provide information about movement and shapes. There are approximately 125 million rods in the human eye.

a rod-shaped cell in the retina that is sensitive to dim light (Morris 1992).

terminal part of the dendrite of a photoreceptor (sensory neuron) in the retina, responsible for perception of grey tones at low light intensities.

A photoreceptor responsible for vision in dim lighting.

Receptor found in the retina important for in low lightconditions.

visual receptor cell sensitive to dim light

One of the two main classes of photoreceptor found in the vertebrate eye. Rods are very sensitive to light but fail to produce a usable signal at high light levels. They mediate night vision and have little effect on color vision in daylight.

A photosensitive receptor in the retina that helps you to see in low light. Go to Top

A sensory neuron located in the periphery of the retina. It is sensitive to light of low intensity and specialized for nighttime vision.

Receptor found in the retina important for in low light conditions.

The low-light receptors on the retina, used principally at night. Rods only see variations in brightness, not color.
