腹侧流的高级别区域对面孔、房屋或物体等刺激表现出很强的类别选择性。然而，最近的研究表明，这种选择性至少部分源于不同类别的图像固有的低水平差异。例如，当与面部或对象图像相比时，视觉室外和室内场景以及房屋在空间频率、直线性和倾斜度上不同。相应地，场景反应的para-hippocampal位置区（PPA）表现出强烈的偏好，低层次的视觉场景的属性，也在没有高层次的场景内容。这就提出了一个问题，即PPA、梭状面区（FFA）或客体反应性枕叶外侧复合体（OCTX）的所有高水平反应是否都可以用低水平特征的系统差异来解释。在本研究中，我们对比了两类简单的刺激组成的10个矩形。虽然两者在视觉低级特征上是匹配的，但只有一类矩形排列产生了与高级3D布局（如场景或对象）兼容的概念。我们发现，PPA，枕横沟（TOS，也被称为枕位区，OPA），以及FFA和FFA显示出强大的响应视觉场景类相比，低水平的匹配控制。我们的研究结果表明，视觉类别反应区不纯粹是由低层次的视觉特征，但也由高层次的知觉刺激解释。
High-level regions of the ventral stream exhibit strong category selectivity to stimuli such as faces, houses, or objects. However, recent studies suggest that at least part of this selectivity stems from low-level differences inherent to images of the different categories. For example, visual outdoor and indoor scenes as well as houses differ in spatial frequency, rectilinearity and obliqueness when compared to face or object images. Correspondingly, scene responsive para-hippocampal place area (PPA) showed strong preference to low-level properties of visual scenes also in the absence of high-level scene content. This raises the question whether all high-level responses in PPA, the fusiform face area (FFA), or the object-responsive lateral occipital compex (LOC) may actually be explained by systematic differences in low-level features. In the present study we contrasted two classes of simple stimuli consisting of ten rectangles each. While both were matched in visual low-level features only one class of rectangle arrangements gave rise to a percept compatible with a high-level 3D layout such as a scene or an object. We found that areas PPA, transverse occipital sulcus (TOS, also referred to as occipital place area, OPA), as well as FFA and LOC showed robust responses to the visual scene class compared to the low-level matched control. Our results suggest that visual category responsive regions are not purely driven by low-level visual features but also by the high-level perceptual stimulus interpretation.
