Patterns of dark dominance in cortical input from simple visual stimuli. A. CooperEmily M. NorciaAnthony 2015 <p>(A) Images of a small bright bar and dark bar (10 arcmin wide, 30 arcmin tall, on a 50 arcmin square) were shown to the model RGCs. For each bar, the response for all RGCs over the whole square, (both ON and OFF) were summed together and weighted by a factor of 9:1 for P pathway to M pathway. Example responses are shown for the foveal P pathway cells. (B) Resulting prediction for the magnitude of the afferent signals to primary visual cortex stimulated by the bright and dark bars.</p>
