Animals must infer the three-dimensional structure of the surrounding world from two-dimensional images on their retinas. For instance, animals use visual cues like motion parallax and binocular disparity to judge distances to objects as they navigate their environment. Although studies in several vision models have found neural activity that correlates with distance signals, the causal behavioral role of neurons and the range of possible properties that inform distance perception have remained poorly understood. Here, we developed a novel high-throughput behavioral assay to identify neurons i
