动物利用感官从周围的世界中获取信息，因此它们需要能够测量环境的物理属性，以便建立对环境的准确感知。例如，蝙蝠需要“知道”声速，以估计物体的距离，尽管输入到感官系统的信息往往会利用比这更复杂的属性。在这里，我们测量的风感应系统的美洲大蠊（美洲大蠊）的一个复杂的流体动力学流的响应。我们发现昆虫的中间神经元传递有关风的光谱特性的关键信息，这可能会警告它接近捕食者。
Animals use their senses to extract information from the world around them, so they need to be able to gauge the physical properties of their environment in order to build up an accurate perception of it. For example, a bat needs to ‘know’ the velocity of sound to estimate how far away an object is, although input to a sensory system may often exploit more complicated properties than this. Here we measure the response by the wind-sensing system of the American cockroach (Periplaneta americana) to a complex hydrodynamic flow. We find that the insect's interneurons relay crucial information about the wind's spectral properties, which may warn it of approaching predators.
