In nature, diverse sensory signals fluctuate in time and in space. Odors, for example, are distorted by wind into narrow filaments. When multiple spatially distinct odor sources exist, these filaments interleave but do not intermix. Such odor landscapes pose complementary challenges to animals – such as the fruit fly – that depend on olfaction to find food or mating partners. First, to select the best odor to track back to its source, the olfactory system must compare information from different filaments over relatively long timescales. Second, to remain on high alert to unexpected changes, su
