Similarly, blue and violet hues are perceived when the S receptor is stimulated more. Meer weergeven Cone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes including the human eye. They respond differently to light of different wavelengths, and the combination of their responses is responsible for Meer weergeven Types Humans normally have three types of cones, usually designated L, M and S for long, medium and short wavelengths respectively. The first responds the most to light of the longer red wavelengths, peaking at … Meer weergeven • Achromatopsia (Rod monochromacy) - a form of monochromacy with no functional cones • Blue cone monochromacy - a rare form of monochromacy with only functional S-cones Meer weergeven • Cell Centered Database – cone cell • Photoreceptors - Webvision • NIF Search – Cone Cell via the Neuroscience Information Framework Meer weergeven The difference in the signals received from the three cone types allows the brain to perceive a continuous range of colors, through the opponent process of color vision.
