CSP: type of specialized light-sensitive cell (photoreceptor) in the retina of the eye that provides sharp central vision and color vision.,MSH: Photosensitive afferent neurons located primarily within the FOVEA CENTRALIS of the MACULA LUTEA. There are three major types of cone cells (red, blue, and green) with photopigments of different spectral sensitivity curves. Retinal cone cells operate in daylight vision (at photopic intensities) providing color recognition and central visual acuity.,NCI: One of the two photoreceptor cell types in the vertebrate retina. Cones are less sensitive to light than rods, but they provide vision with higher spatial and temporal acuity, and the combination of signals from cones with different pigments allows color vision.
