Perceptual filling-in can be used asan effective tool to probe the characterof visual representations. For example,does perceptual filling-in imply that thebrain ‘reconstructs’ the visual scene,thus supporting the percept reportedby subjects? For instance, is the brighttriangle perceived in Fig. 1A caused byan associated pattern of firing in topo-graphically organized visual areas, suchas cortical area V2? Or are more ‘cogni-tive’ or symbolic processes (which are,to be sure, also associated with under-lying neural processes) involved? Forinstance, in Figs 1B and 1C are our per-cepts the result of mechanisms thatsimply tag an entire region with a‘more-of-the-same’ label? A careful ex-amination of the data shows that nogeneral inferences are possible

为什么大脑会充满？

感知填充可以作为探索视觉表征特征的有效工具。例如，知觉填充是否意味着大脑“重构”了视觉场景，从而支持了受试者报告的知觉？例如，图 1A 中感知到的亮三角形是否是由地形组织的视觉区域（例如皮层区域 V2）中的相关放电模式引起的？或者是否涉及更多的“认知”或符号过程（当然，它们也与潜在的神经过程相关）？例如，在图 1B 和 1C 中，我们的感知是简单地用“更多相同”标签标记整个区域的机制的结果吗？对数据的仔细检查表明不可能进行一般性推论
