感受野的空间处理是视觉系统的核心特性。然而，尚不清楚高级区域中的空间处理如何有助于识别行为。由于人脸倒置被认为会破坏人脸中典型的整体信息处理，我们在人类视觉系统中绘制了直立和倒置人脸的群体感受野（pRFs）。在这里，我们表明，在面部选择性区域，而不是初级视觉皮层，pRFs和整体视野覆盖范围较小，并向下移动，以响应面部反转。从这些测量结果中，我们成功地预测了在视野中的不同位置的脸反转的相对行为损害。神经测量和行为之间的这种对应关系表明，面部选择性区域的空间处理如何使整体感知成为可能。这些结果不仅表明，在高层次的视觉区域的空间处理是动态地用于识别，但也提出了一个强大的方法桥接神经计算的感受野的行为。目前尚不清楚腹侧（“什么”）流的空间处理是否有助于高水平的视觉识别。在这里，作者表明，空间处理的脸选择性区域直接有助于整个人脸识别行为。
Spatial processing by receptive fields is a core property of the visual system. However, it is unknown how spatial processing in high-level regions contributes to recognition behavior. As face inversion is thought to disrupt typical holistic processing of information in faces, we mapped population receptive fields (pRFs) with upright and inverted faces in the human visual system. Here we show that in face-selective regions, but not primary visual cortex, pRFs and overall visual field coverage are smaller and shifted downward in response to face inversion. From these measurements, we successfully predict the relative behavioral detriment of face inversion at different positions in the visual field. This correspondence between neural measurements and behavior demonstrates how spatial processing in face-selective regions may enable holistic perception. These results not only show that spatial processing in high-level visual regions is dynamically used towards recognition, but also suggest a powerful approach for bridging neural computations by receptive fields to behavior. It is unknown whether spatial processing in the ventral (‘what’) stream contributes to high-level visual recognition. Here the authors show that spatial processing in face-selective regions directly contributes to whole face recognition behavior.
