摘要

摘要夜间候鸟利用地球磁场来确定它们想要迁徙的方向。许多研究表明，这种“磁罗盘感”是光依赖性的，由蓝光传感器介导，称为隐色素，在夜间候鸟的视网膜中表达。在这篇综述中，我们总结了鸟类视网膜不仅处理视觉信息，还处理磁罗盘信息的证据。我们还回顾了目前关于鸟类视网膜中隐花色素表达的知识，并强调了我们旨在在SFB 1372脊椎动物磁接收和导航框架内解决的悬而未决的问题。

The retinal circuitry for magnetoreception in migratory birds

Abstract Night-migratory birds use the Earth’s magnetic field to determine the direction in which they want to migrate. Many studies suggest that this “magnetic compass sense” is light dependent and mediated by blue light sensors, called cryptochromes, which are expressed in the retina of night-migratory birds. In this review, we summarize the evidence that the avian retina processes not only visual information but also magnetic compass information. We also review the current knowledge on cryptochrome expression in the bird retina and highlight open questions which we aim to address within the framework of SFB 1372 Magnetoreception and Navigation in Vertebrates.
