In the 1970s Charlie Gross was among the first to identify neurons that respond selectively to faces, in the macaque inferior temporal (IT) cortex. This seminal finding has been followed by numerous studies quantifying the visual features that trigger a response from face cells in order to answer the question; what do face cells want? However, the connection between face-selective activity in IT cortex and visual perception remains only partially understood. Here we present fMRI results in the macaque showing that some face patches respond to illusory facial features in objects. We argue that to fully understand the functional role of face cells, we need to develop approaches that test the extent to which their response explains what we see.
20 世纪 70 年代，查理·格罗斯（Charlie Gross）率先在猕猴的下颞叶（IT）皮质中发现了对人脸有选择性反应的神经元。这一开创性的发现之后，有许多研究对触发人脸细胞反应的视觉特征进行了量化，以回答这个问题：“人脸细胞想要什么？”然而，IT 皮层中选择性的面孔活动与视觉感知之间的联系仍然只是部分理解。在这里，我们呈现了猕猴的 fMRI 结果，表明一些面孔区域会对物体中的虚幻面部特征做出反应。我们认为，要全面了解面孔细胞的功能作用，我们需要开发一些方法来检验其反应在多大程度上解释了我们所看到的东西。
