photoreceptors that are most sensitive to light and more numerous than cones. The provide vision in dim light and are more capable of detecting movement.
A type of photoreceptor cell; sensitive to dim light, but not to color; found primarily in the periphery of the retina.
Photoreceptors in retina. Operate in scotopic vision.
The retinal photoreceptors responsible for twilight (scotopic) vision. So called because of their shape.
They are receptors that are sensitive to light and dark.
Photoreceptor cells in the retina of the eye that are responsible for night vision and detection of motion.
The detectors in the retina which are sensitive to low levels of light. They sense brightness and darkness (like black and white film) but not color.
The sensory receptors of the retina that are active in dim light and do not perceive color.
Retinal receptor cells responsible for peripheral vision under reduced illumination.
Retinal receptors that respond to low levels of luminance but cannot distinguish hues. Not present in the center of the fovea region.
Photoreceptors in the retina of the human eye that are sensitive to low light levels.
Specialized receptor cells in the retina that provide black-and-white vision. 648
light-sensitive cells in the retina that work best in darkness or dim illuminations
The receptors in the retina which are sensitive to variations in achromatic brightness.
One of two types of photoreceptive sensors in the retina. Rods work best in dim light and allow black and white vision.
Long, slender structures within the retina that perceive faint light. Also, rod-shaped bacteria (bacilli).
Long, slender structures located within the peripheral retina that provide vision in dim light.
opposite of cones, catch shapes, objects, light intensity Term Meaning
Light receptors in primates' eyes that provide vision in dim light.
light-sensitive cells located in the peripheral (side) areas of the retina. They are responsible for detecting movement, shape, light and dark. The visual picture provided by rods is in black and white.
Light sensitive receptor cells mostly found in the peripheral part of the retina. They are responsible for night vision.
light sensitive cells located primarily in the peripheral retina, sensitive to movement and light, even low intensity
Light-sensitive retinal cells that make it possible to see in dim light. These cells are shaped like rods.
One of the two principal nerve endings of the retina which are highly sensitive to low variations in illumination but relatively insensitive to color differences.
Light-sensitive cells (photoreceptors) in the retina. (Contrast with cones.)
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. See cones.
Cells in the retina that enable vision in darkness or dim light.
Rod cells One type of specialized light-sensitive cells (photoreceptors) in the retina that provide side vision and the ability to see objects in dim light (night vision). Also see Cones. Scotoma An area of partial or complete loss of vision surrounded by an area of normal vision.
Photoreceptor cells in the retina that respond to low levels of light. They are not thought to contribute to color vision. See cones.
photoreceptor cells in the retina that are primarily responsible for peripheral vision and vision in dim light
one type of specialized light-sensitive cells (photoreceptors) in the retina that provide peripheral vision and the ability to see objects in dim light, used extensively for night vision. The rods lie outside the fovea in the more peripheral parts of the retina. Most nocturnal animals rely solely on the use of rods for their vision (also see cones) as this allows them to perceive as much as possible visual information in conditions of low illumination.

Photoreceptors in the retina that respond to lower light intensities and give rise to achromatic (colorless) sensations.
These are the black and #53ACAC light receptors for the eye. The rods work best under low light conditions.
Cylindarshaped photoreceptors participating in peripheral vision under conditions of low light. ( bâtonnets, n.m)
A subtype of photoreceptor found in the vertebrate retina. Rods are more sensitive to light than cones are responsible for vision under dim illumination.
Light-sensitive cells that form a layer of the retina and act as light-receiving media. Rods are sensitive to motion and vision at low degrees of illumination (scotopic vision). Go to top of page
receptors forming part of the retina at the back of the eye sensitive only to variations in brightness, not color.
