Role of Supramarginal Gyrus in the Integration of Visual Features Across Eye Movements

视觉通过快速的眼球运动（称为扫视）不断增强，导致短暂的稳定注视之间频繁的时空中断。因此，视觉特征的跨扫视整合（TSI）是视觉感知的基础，并形成了一个理想的模型系统，用于理解视觉系统中不同信号之间的相互作用。在我们之前的NSERC资助的工作中，我们确定了一个有助于TSI的皮层区域网络，包括额叶和顶叶眼区，背外侧前额叶皮层和早期视觉皮层。但到目前为止，跨扫视特征存储和整合发生的关键部位仍然难以捉摸。

Vision is constantly augmented by rapid eye movements called saccades, resulting in frequent spatiotemporal interruptions between brief periods of stable fixation. Trans-saccadic integration of visual features (TSI) is thus fundamental to visual perception, and forms an ideal model system for understanding interactions between different signals in the visual system. In our previous NSERC-funded work we identified a network of cortical areas that contribute to TSI, including the frontal and parietal eye fields, dorsolateral prefrontal cortex, and early visual cortex. But until now, the key site(s) where trans-saccadic feature storage and integration occurs has remained elusive.
