We offer a critique of Ishai's [Ishai, A., 2008. Let's face it: it's a cortical network. NeuroImage. doi:10.1016/j.neuroimage.2007.10.040] comment on the value of considering the brain areas that support face perception as a network. We emphasise that this idea is not in opposition to the notion that the fusiform gyrus plays a key role in the visual analysis of faces. More important, we argue that the definition offered of the "extended" face network--areas showing a greater fMRI response to intact than scrambled face images--is too inclusive, and present data to indicate that at least two of the proposed "nodes" of this network also respond to non-face objects (compared to scrambled controls). Finally, we consider briefly how converging methodological approaches may augment the use of fMRI alone in understanding how anatomically widespread brain areas coordinate their activity in order to make sense of the human face.
我们对伊沙伊[伊沙伊，A.，2008年。面对现实吧：这是一个皮质网络。《神经影像学》。doi:10.1016/j.neuroimage.2007.10.040]关于将支持面部感知的脑区视为一个网络的价值的评论进行了批判。我们强调，这一观点并不与梭状回在面部视觉分析中起关键作用的观点相矛盾。更重要的是，我们认为所提供的“扩展”面部网络的定义——与杂乱面部图像相比，对完整面部图像显示出更大功能磁共振成像反应的区域——过于宽泛，并提供数据表明该网络中至少两个拟议的“节点”对非面部物体也有反应（与杂乱对照组相比）。最后，我们简要考虑了多种方法如何协同使用，以增强仅使用功能磁共振成像来理解解剖学上广泛分布的脑区如何协调其活动以识别人脸的能力。
