面部感知依赖于面部选择性皮层区域进行的计算。这些领域已经被深入研究了20年，这项工作一直受到哈克斯比及其同事在2000年提出的一个有影响力的神经模型的指导。在这里，我们回顾了关于面部选择性区域的新发现，这些发现表明需要对哈克斯比模型进行修改和补充。我们提出了一个修正的框架，其基础是：（a）从早期视觉区域到面部处理系统的多条路线的证据，（B）关于这些区域的时间特征的信息，（c）梭状脸区域有助于感知面部的可变方面的迹象，（d）与静态面部相比，背侧面部选择性脑区对动态面部的反应大大提高，以及（e）识别三个新的前面部选择性区域。总之，这些发现使我们认为，面部知觉取决于两个独立的途径：一个腹侧流，代表形式信息和背侧流驱动的运动和形式信息。
Face perception relies on computations carried out in face-selective cortical areas. These areas have been intensively investigated for two decades, and this work has been guided by an influential neural model suggested by Haxby and colleagues in 2000. Here, we review new findings about face-selective areas that suggest the need for modifications and additions to the Haxby model. We suggest a revised framework based on (a) evidence for multiple routes from early visual areas into the face-processing system, (b) information about the temporal characteristics of these areas, (c) indications that the fusiform face area contributes to the perception of changeable aspects of faces, (d) the greatly elevated responses to dynamic compared with static faces in dorsal face-selective brain areas, and (e) the identification of three new anterior face-selective areas. Together, these findings lead us to suggest that face perception depends on two separate pathways: a ventral stream that represents form information and a dorsal stream driven by motion and form information.
