The authors monitored neuronal activity in mouse visual cortex during visual-motion stimulation and perturbed retinal direction selectivity. After perturbation, the proportion of posterior-motion-preferring cortical cells decreased, and their response at higher stimulus speeds was reduced. Thus, functionally distinct, retina-dependent and retina-independent computations of visual motion exist in mouse cortex.
