就像飞蛾扑火一样,趋光性是先天偏好的一个标志性例子。这种偏好可能反映了对可预测情况的进化适应,并且传统上被概念化为硬连线的刺激-反应联系。也许正是因为这个原因,果蝇趋光性的灵活性这一长达一个世纪的发现很少受到关注。在这里,我们报告说,在几种不同的行为测试中,步行测试的明/暗偏好取决于飞行的各个方面。如果我们暂时损害飞行能力,步行的摄影偏好也会随之逆转。分别表达多巴胺和章鱼胺的回路中的神经元活动在光偏好中发挥着不同的作用,这表明这些生物胺可能参与这种行为灵活性的情况。我们得出的结论是,苍蝇监控它们的飞行能力,并且飞行能力对果蝇的行动选择产生根本性影响。这项工作表明,即使是看似简单且固有的行为也包含一个价值驱动的决策阶段,在选择行动之前,将外部情况与动物的内部状态进行协商。
Like a moth into the flame—phototaxis is an iconic example for innate preferences. Such preferences probably reflect evolutionary adaptations to predictable situations and have traditionally been conceptualized as hard-wired stimulus–response links. Perhaps for that reason, the century-old discovery of flexibility in Drosophila phototaxis has received little attention. Here, we report that across several different behavioural tests, light/dark preference tested in walking is dependent on various aspects of flight. If we temporarily compromise flying ability, walking photopreference reverses concomitantly. Neuronal activity in circuits expressing dopamine and octopamine, respectively, plays a differential role in photopreference, suggesting a potential involvement of these biogenic amines in this case of behavioural flexibility. We conclude that flies monitor their ability to fly, and that flying ability exerts a fundamental effect on action selection in Drosophila. This work suggests that even behaviours which appear simple and hard-wired comprise a value-driven decision-making stage, negotiating the external situation with the animal's internal state, before an action is selected.
