视觉场景被快速分割成不同对象和背景所占据的区域。分割可以从边界的检测开始，然后填充这些边界之间的表面以使它们可见。可替代地，分割可以基于相似的表面元素的分组，使得边界被（隐含地）识别为被分组为对象的元素之间的边界。在这里，我们呈现了来自清醒的猴子初级视觉皮层的记录，其显示在神经反应的晚期（>80 ms）组分中表达了边界形成的相关性，随后在边缘之间填充（也称为着色）。这些数据有利于分割模型，其中边界形成启动表面填充。
A visual scene is rapidly segmented into the regions that are occupied by different objects and background. Segmentation may be initiated from the detection of boundaries, followed by the filling in of the surfaces between these boundaries to render them visible. Alternatively, segmentation may be based on grouping of surface elements that are similar, so that boundaries are (implicitly) identified as the borders between elements that are grouped into objects. Here, we present recordings from awake monkey primary visual cortex that show that in late (>80 ms) components of the neural responses a correlate of boundary formation is expressed, followed by a filling in (also called colouring) between the edges. These data favour a model of segmentation where boundary formation initiates surface filling-in.
