This paper reviews processing of facial identity and expressions. The issue of independence of these two systems for these tasks has been addressed from different approaches over the past 25 years. More recently, neuroimaging techniques have provided researchers with new tools to investigate how facial information is processed in the brain. First, findings from "traditional" approaches to identity and expression processing are summarized. The review then covers findings from neuroimaging studies on face perception, recognition, and encoding. Processing of the basic facial expressions is detailed in light of behavioral and neuroimaging data. Whereas data from experimental and neuropsychological studies support the existence of two systems, the neuroimaging literature yields a less clear picture because it shows considerable overlap in activation patterns in response to the different face-processing tasks. Further, activation patterns in response to facial expressions support the notion of involved neural substrates for processing different facial expressions.

处理面部和面部表情。

本文回顾了面部身份和表情的处理。在过去的25年中，已经通过不同的方法解决了这两个系统完成这些任务的独立性问题。最近，神经影像技术为研究人员提供了新的工具，以研究如何在大脑中处理面部信息。首先，总结了来自“传统”身份和表达处理方法的发现。然后，本综述涵盖了神经影像学研究在面部感知，识别和编码方面的发现。根据行为和神经影像数据详细介绍了基本面部表情的处理。鉴于实验和神经心理学研究的数据支持两个系统的存在，神经影像文献产生的图像不太清晰，因为响应于不同的面部处理任务，其在激活模式中显示出相当大的重叠。此外，响应于面部表情的激活模式支持所涉及的用于处理不同面部表情的神经基质的概念。
