Gridness score average as a function of (A) sensory current gain and (B) average number of visible markers. The shadow areas represent the standard error of the mean. (A) The stabilization mechanism works best if velocity-dependent currents and sensory currents are balanced. (B) The optimal current sensory gain k depends on the average number of visible markers. The stabilization performance gets worse when the current sensory gain is constant (blue line) than when it is inversely proportional to the average number of visible markers (red line).
