The mammalian superior colliculus (SC) and its non-mammalian homolog, the optic tectum are implicated in sensorimotor transformations. Historically, emphasis on visuomotor functions of the SC has led to a popular view that it operates as an oculomotor structure rather than a more general orienting structure. In this review, we consider comparative work on the SC/optic tectum, with a particular focus on non-visual sensing and orienting, which reveals a broader perspective on SC functions and their role in species-specific behaviors. We highlight several recent studies that consider ethological context and natural behaviors to advance knowledge of the SC as a site of multi-sensory integration and motor initiation in diverse species.
哺乳动物的上丘（SC）及其非哺乳动物同源物，视顶盖，参与感觉运动转换。从历史上看，对 SC 的视觉运动功能的强调导致了一种流行的观点，即它作为一个眼球运动结构而不是一个更普遍的定向结构发挥作用。在这篇综述中，我们考虑了 SC/视顶盖的比较研究，特别关注非视觉传感和定向，这揭示了 SC 功能的更广泛视角及其在特定物种行为中的作用。我们强调了几项最近的研究，这些研究考虑了行为学背景和自然行为，以提高对 SC 作为多种物种中多感觉整合和运动启动的部位的认识。
