Most vertebrates use head and eye movements to quickly change gaze orientation sample different portions of the environment with periods stable fixation. Visual information must be integrated across fixations construct a complete perspective visual environment. In concert this sampling strategy, neurons adapt unchanging input conserve energy ensure that only novel from each fixation is processed. We demonstrate how adaptation recovery times saccade properties interact thus shape spatiotemporal tradeoffs observed in motor systems mice, cats, marmosets, macaques, humans. These predict order achieve similar coverage over time, animals smaller receptive field sizes require faster rates. Indeed, we find comparable by neuronal populations mammals when integrating measurements saccadic behavior V1 density. propose these share common statistically driven strategy maintaining their time calibrated respective system characteristics.
