Abstract

Despite extensive evidence for regions of human visual cortex that respond selectively to faces, few studies have considered the cortical representation of the appearance of the rest of the human body. We present a series of functional magnetic resonance imaging (fMRI) studies revealing substantial evidence for a distinct cortical region in humans that responds selectively to images of the human body, as compared with a wide range of control stimuli. This region was found in the lateral occipitotemporal cortex in all subjects tested and apparently reflects a specialized neural system for the visual perception of the human body.

摘要

尽管有大量证据表明人类视觉皮层中存在对面部有选择性反应的区域,但很少有研究考虑过人体其他部位外观的皮层表征。我们进行了一系列功能磁共振成像(fMRI)研究,发现有大量证据表明,与多种对照刺激相比,人类存在一个独特的皮层区域,该区域对人体图像有选择性反应。在所有测试对象的外侧枕颞皮层中都发现了这个区域,它显然反映了一个专门用于人体视觉感知的神经系统。
