Visual motion on the retina activates a cohort of retinal ganglion cells (RGCs). This population activity encodes multiple streams of information extracted by parallel retinal circuits. Motion processing in the retina is best studied in the direction-selective circuit. The main focus of this review is the neural basis of direction selectivity, which has been investigated in unprecedented detail using state-of-the-art functional, connectomic, and modeling methods. Mechanisms underlying the encoding of other motion features by broader RGC populations are also discussed. Recent discoveries at both single-cell and population levels highlight the dynamic and stimulus-dependent engagement of multiple mechanisms that collectively implement robust motion detection under diverse visual conditions.

哺乳动物视网膜中运动处理的神经机制。

视网膜上的视觉运动会激活一组视网膜神经节细胞（RGC）。这种人口活动编码并行视网膜电路提取的多个信息流。最好在方向选择电路中研究视网膜中的运动处理。这篇综述的主要重点是方向选择性的神经基础，已使用最先进的功能，连接组学和建模方法对其进行了前所未有的详细研究。还讨论了更广泛的RGC群体对其他运动特征进行编码的机制。在单细胞和群体水平上的最新发现突出了多种机制的动态和依赖刺激的参与，这些机制共同在各种视觉条件下实现了强大的运动检测。
