动物的行为是灵活的，可以根据环境、营养状况甚至年龄等因素发生显着变化。然而，外部和内部线索如何改变先天行为的神经基础尚不清楚。例如，果蝇（Drosophila melanogaster）天生就会被醋吸引或排斥，这取决于醋的浓度。年龄改变了果蝇的先天避光行为，在老年幼虫中变成了光偏好。这种行为转变可能是一种适应，发生在年长的幼虫离开食物来源，从而离开黑暗，在光明中寻找合适的种群位置。在这期杂志的499页，Gonget等人发现了果蝇幼虫大脑中控制行为转换的两对神经元。
The behavior of animals is flexible and can change dramatically in response to the environment, nutritional state, or even age, among other factors. However, the neural basis of how external and internal cues modify innate behavior is not clearly understood. For example, the fruit flyDrosophila melanogasteris inherently either attracted or repelled by vinegar depending on its concentration . And age changes the innate light avoidance behavior of youngDrosophilalarvae into light preference in older larvae . The behavioral switch may be an adaptation that occurs as older larvae leave their food source—and thus darkness—to search for a suitable population site in the light. On page 499 of this issue, Gonget al.identify two pairs of neurons in theDrosophilalarval brain that control behavioral switch.
