标题： Neural encoding of real world face perception

摘要： 社会知觉随着我们自由地与周围的人互动而展开。 我们研究了在与朋友、家人和其他人自发互动时，人类在大脑内多电极皮层记录下真实世界面孔感知的神经基础。 计算模型仅从大脑活动重建了参与者在自然互动中所看的面部，包括面部表情和动作。 结果强调了社会视觉通路，即跨越顶叶、颞叶和枕叶皮质区域的一个网络，发挥了关键作用。 与强烈的表情相比，该网络对微妙的表情表现出更敏锐的调谐，这一点通过控制的心理物理实验得到了证实。 这些发现揭示，在现实生活中真实的社会互动中，人类的社会视觉通路将面部表情和动作编码为相对于中性表情原型的偏差。 显示英文摘要

摘要： Social perception unfolds as we freely interact with people around us. We investigated the neural basis of real world face perception using multi electrode intracranial recordings in humans during spontaneous interactions with friends, family, and others. Computational models reconstructed the faces participants looked at during natural interactions, including facial expressions and motion, from brain activity alone. The results highlighted a critical role for the social vision pathway, a network of areas spanning parietal, temporal, and occipital cortex. This network was more sharply tuned to subtle expressions compared to intense expressions, which was confirmed with controlled psychophysical experiments. These findings reveal that the human social vision pathway encodes facial expressions and motion as deviations from a neutral expression prototype during natural social interactions in real life.
