这项研究考察了早期人类社会认知能力的大脑基础。具体来说，我们调查了是否涉及成人的面部通信信号的感知皮层区域在人类早期发育的功能活跃。四个月大的婴儿观察了两种动态场景，其中一张脸要么建立相互凝视，要么转移视线，这两种情况都伴随着眉毛抬起并伴随着微笑。血流动力学反应进行了测量，近红外光谱，允许空间定位的大脑激活（实验1），γ-波段振荡脑活动进行了分析，从脑电图提供有关的皮层过程的时间信息（实验2）。结果显示，感知面部交流信号会激活婴儿颞叶和前额皮质中的区域，这些区域与成年人参与这些过程的大脑区域相对应。此外，相互凝视本身以及在相互凝视的背景下扬起眉毛并伴随微笑，也会产生类似的皮质激活。这种结果模式表明，参与面部交流线索感知的皮层网络早期专业化，这对婴儿与他人互动和学习至关重要。
This study examined the brain bases of early human social cognitive abilities. Specifically, we investigated whether cortical regions implicated in adults' perception of facial communication signals are functionally active in early human development. Four-month-old infants watched two kinds of dynamic scenarios in which a face either established mutual gaze or averted its gaze, both of which were followed by an eyebrow raise with accompanying smile. Haemodynamic responses were measured by near-infrared spectroscopy, permitting spatial localization of brain activation (experiment 1), and gamma-band oscillatory brain activity was analysed from electroencephalography to provide temporal information about the underlying cortical processes (experiment 2). The results revealed that perceiving facial communication signals activates areas in the infant temporal and prefrontal cortex that correspond to the brain regions implicated in these processes in adults. In addition, mutual gaze itself, and the eyebrow raise with accompanying smile in the context of mutual gaze, produce similar cortical activations. This pattern of results suggests an early specialization of the cortical network involved in the perception of facial communication cues, which is essential for infants' interactions with, and learning from, others.
