Afterimages and Multiplexing

D.H. Kelly and Eugenio Martinez-Uriegas

There is much current interest in the functions of parallel pathways in vision and, in particular, the question of where and how the opponent-color and luminance signals are formed. According to several lines of evidence, chromatic and achromatic signals both share a common pathway from the retina to the brain; namely, the "sustained" or parvocellular pathway. Our recent results imply that the same multiplexing arrangement also holds for chromatic and achromatic afterimages, surely the most "sustained" phenomena in normal vision.
