Eye saccades align optic flow with retinal specializations during object pursuit in freely moving ferrets.

During prey pursuit, how eye-rotations, such as saccades, enable continuous tracking of erratically moving targets while simultaneously enabling an animal to navigate through the environment is unknown. To better understand this, we measured head and eye rotations in freely running ferrets during pursuit behavior. By also tracking the target and all environmental features we reconstructed the animal’s visual fields and their relationship to retinal structures. In the reconstructed visual fields, the target position clustered on and around the high acuity retinal area location, the area centralis, and surprisingly this cluster was not significantly shifted by digital removal of either eye saccades, exclusively elicited when the ferrets made turns, or head rotations which were tightly synchronized with the saccades. Here we show that, while the saccades did not fixate the moving target with the area centralis, they instead aligned the area centralis with the intended direction of travel. ...,

在猎物追踪过程中，眼球扫视（saccades）这类眼球转动如何支持对不规则运动目标的持续追踪，同时协助动物在环境中导航，这一问题目前仍未得到解答。为深入解析这一问题，我们在自由奔跑的雪貂进行追踪行为时，测量了其头部与眼球的转动情况。同时通过追踪目标与所有环境特征，我们重建了该动物的视野及其与视网膜结构的关联。在重建的视野中，目标位置聚集在高敏度视网膜区域——视网膜中央区（area centralis）及其周边；令人意外的是，通过数字化移除仅在雪貂转向时触发的眼球扫视，或是移除与扫视紧密同步的头部转动后，该目标聚集区域并未出现显著偏移。本研究证实，尽管眼球扫视并未通过视网膜中央区固定移动目标，却能将视网膜中央区与动物的预设行进方向对齐。……
