Cone cells or cones are photoreceptor cells in the retinas of vertebrates' eyes. They respond differently to light of different wavelengths, and the combination...

mammalian eyes: rods, cones, and intrinsically photosensitive retinal ganglion cells. The two classic photoreceptor cells are rods and cones, each contributing...

Double cones (DCs), known as twin cones when the two members are the same, are two cone cells (colour detecting photoreceptors) joined together that may...

channels for conveying color information, or possessing four types of cone cell in the eye. Organisms with tetrachromacy are called tetrachromats. In...

Rod cells are photoreceptor cells in the retina of the eye that can function in lower light better than the other type of visual photoreceptor, cone cells...

As a part of the retina, bipolar cells exist between photoreceptors (rod cells and cone cells) and ganglion cells. They act, directly or indirectly, to...

up: Perception of color begins with specialized retinal cells known as cone cells. Cone cells contain different forms of opsin – a pigment protein – that...

light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different...

many other animals, photopic vision allows color perception, mediated by cone cells, and a significantly higher visual acuity and temporal resolution than...

in the cone cell cyclic nucleotide-gated ion channels CNGA3 (ACHM2) and CNGB3 (ACHM3), the cone cell transducin, GNAT2 (ACHM4), subunits of cone phosphodiesterase...

conveying color information, derived from the three different types of cone cells in the eye. Organisms with trichromacy are called trichromats. The normal...

belt, where the ganglion cell layer is composed of more than five layers of cells, as well as the highest density of cones; the perifovea is the outermost...

about color by processing signals from cone and rod cells in an antagonistic manner. The three types of cone cells have some overlap in the wavelengths...

are characterised by initial loss of rod photoreceptor cell function followed by that of the cones and for this reason night blindness is the first significant...

Look up cone or coning in Wiktionary, the free dictionary. A cone is a basic geometrical shape. Cone may also refer to: Cone (category theory) Cone (formal...

viability factor, RdCVF) that protects the cone cells from apoptosis (cell death). However, when the rod cells die, this substance is no longer provided...

distribution of receptor cells across the retina is different between the two main types, rod cells and cone cells. Rod cells are unable to distinguish...

the eye reports input from short wave blue cone cells along with a sub-sensitivity of the long wave cones which respond secondarily to that same deep...

third class of photoreceptors, in addition to rod and cone cells. Compared to the rods and cones, the ipRGCs respond more sluggishly and signal the presence...

variation in the functionality of one or more of the three classes of cone cells in the retina, which mediate color vision. The most common form is caused...

CIELUV color space. The human eye with normal vision has three kinds of cone cells that sense light, having peaks of spectral sensitivity in short ("S",...

may imply that they have been modified from a cone cell ancestor. They occasionally occur in double cones/double rods. Some oil droplets are coloured,...

A cone dystrophy is an inherited ocular disorder characterized by the loss of cone cells, the photoreceptors responsible for both central and color vision...

amacrine cells synapse with retinal ganglion cells. The synapses in the outer plexiform layer are between the rod cell endings or cone cell branched foot...

pigmented epithelial cells. The primary light-sensing cells in the retina are the photoreceptor cells, which are of two types: rods and cones. Rods function...

is the state of having two types of functioning photoreceptors, called cone cells, in the eyes. Organisms with dichromacy are called dichromats. Dichromats...

sight'. In the human eye, cone cells are nonfunctional in low visible light. Scotopic vision is produced exclusively through rod cells, which are most sensitive...

four types of cone cells each with a distinctive maximal absorption peak. In some birds, the maximal absorption peak of the cone cell responsible for...

of cones, rather than each type of cone's individual response.[citation needed][dubious – discuss] Color blindness can be classified by the cone cell that...

mediate vision in vertebrates. They include the opsins in human rod and cone cells. They are often abbreviated to opsin, as they were the first opsins discovered...
