The 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. more
The brain performs its computations based on information from the sensory organs. If this input changes, for instance after an injury, the brain has the ability to adapt. Ideally, after the disturbance has passed, the brain`s processing returns to normal state. Recent studies show that not only the general processing capabilities but also the detailed neural circuits return to their original state. In addition, the work also demonstrates that new neurons can be functionally integrated - even in the adult brain. more
