运动错觉是指在物理刺激中不存在或不同的运动感知。这些错觉是理解视觉神经生物学的一个强大的非侵入性工具，因为它们间接地告诉我们，我们是如何处理运动的。人们普遍认为运动错觉是视觉皮层的高级处理过程，但关于眼球运动和皮层网络在触发运动错觉中的确切作用仍然存在争议。令人惊讶的是，除了人类之外，还没有研究调查动物物种由静态模式引起的全局错觉运动。在这里，我们表明，鱼感知的最研究的运动错觉之一，旋转的蛇。菲什对真实的运动和虚幻的运动的反应相似。复杂的整体错觉运动不仅限于人类，甚至可以在没有皮层的物种中发现，这一事实为开发动物模型以研究运动感知的神经生物学基础铺平了道路。
Motion illusion refers to a perception of motion that is absent or different in the physical stimulus. These illusions are a powerful non-invasive tool for understanding the neurobiology of vision because they tell us, indirectly, how we process motion. There is general agreement in ascribing motion illusion to higher-level processing in the visual cortex, but debate remains about the exact role of eye movements and cortical networks in triggering it. Surprisingly, there have been no studies investigating global illusory motion evoked by static patterns in animal species other than humans. Herein, we show that fish perceive one of the most studied motion illusions, the Rotating Snakes. Fish responded similarly to real and illusory motion. The demonstration that complex global illusory motion is not restricted to humans and can be found even in species that do not have a cortex paves the way to develop animal models to study the neurobiological bases of motion perception.
