颜色和运动信息被认为是通过单独的神经通路传递的,但目前尚不清楚这些通路是否以及如何相互作用以改善运动感知。在果蝇等昆虫中,长期以来人们一直认为运动信息仅由一种光谱类别的感光细胞(即所谓的 R1 至 R6 细胞)提供。而 R7 和 R8 感光器存在于多种光谱类别中,有助于色觉。在这里,我们报告 R7 和 R8 也对运动路径有贡献。通过使用电生理学、光学和行为测定,我们发现 R7/R8 信息与运动通路输出融合并塑造运动通路输出,通过其复合反应解释果蝇的广泛调节的视运动行为。我们的结果表明,来自不同光谱灵敏度的光感受器的输入可以改善运动辨别力,提高感知的鲁棒性。
Color and motion information are thought to be channeled through separate neural pathways, but it remains unclear whether and how these pathways interact to improve motion perception. In insects, such as Drosophila, it has long been believed that motion information is fed exclusively by one spectral class of photoreceptor, so-called R1 to R6 cells; whereas R7 and R8 photoreceptors, which exist in multiple spectral classes, subserve color vision. Here, we report that R7 and R8 also contribute to the motion pathway. By using electrophysiological, optical, and behavioral assays, we found that R7/R8 information converge with and shape the motion pathway output, explaining flies’ broadly tuned optomotor behavior by its composite responses. Our results demonstrate that inputs from photoreceptors of different spectral sensitivities improve motion discrimination, increasing robustness of perception.
