SummaryThe perception and reaction to food odors and tastes can change dependent on internal state and needs. How these perceptual changes are brought about is not well understood. Recent findings have shown that female fruit flies (Drosophila melanogaster) change their perception and behavior after mating to preferring polyamine-rich diets, which they identify with specific odor and taste receptors. The results suggest that physiological needs influence sensory perception and, ultimately, behavior, enhancing reproductive success and survival.
