Topic: wingbeat responses

High noise tolerance is a hallmark of sensory systems as external stimuli are intrinsically noisy. However, the neural mechanisms underlying the noise tolerance are not clearly understood. In Drosophila vision, we evaluated behavioral and physiological changes in visual responses to simple visual patterns––translating bars, gratings, spots, and looming objects––overlaid with varying levels of salt-and-pepper noise. In tethered, flying Drosophila, we found that the noise tolerance, evaluated by changes in visually evoked wingbeat responses, depends on the pattern. Namely, the noise tolerance wa
