  • Title: Numerical study of short-term afterimages and associate properties in foveal vision.
    Author: Momiji H, Bharath AA, Hankins MW, Kennard C.
    Journal: Vision Res; 2006 Feb; 46(3):365-81. PubMed ID: 16297956.
    Abstract:
    A cellular model of the primate retina has been developed. Unlike existing models, it incorporates spatial non-uniformities, such as the random arrangement of L and M cones, and the radial dilation with eccentricity. Based on a population of ganglion cell activities, colour-image representation is modelled with the luminance and the R-G opponent channels. The developed model reproduces experimentally known properties in temporal and spatial vision. Furthermore, spatio-temporally coupled properties such as transition from positive to negative phases in an afterimage, are recapped. In colour vision, the model can explain the insensitivity in our colour perception to the L/M cone ratio.
