The primary visual cortex (V1) carries signals related to visual speed, and its responses are also affected by run speed. Here the authors report that nearly half of the V1 neurons were reliably driven by combinations of visual speed and run speed. As a population, V1 neurons predicted a linear combination of visual and run speed better than visual or run speeds alone.
