WebA plot of visual sensitivity versus wavelength for cone vision. Often measured by presenting a small spot of light to the fovea, which contains only cones. Can also be measured when the eye is light adapted, so cones are the most sensitive receptors. Convergence. When many neurons synapse onto a single neuron. http://hyperphysics.phy-astr.gsu.edu/hbase/vision/colcon.html

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 color vision. Cones function best in relatively bright light, called the photopic region, as opposed to rod cells, which work better in dim light, or the scotopic region. Cone cells are … WebThe volume of cone: Volume of cylinder = 1/3: 1. = 1:3. Therefore, the ratio of the volume of a cone to the volume of a cylinder is 1:3.
