The capacity to engage and communicate in a social world is one of the defining characteristics of the human species. While the network of regions that compose the social brain have been the subject of extensive research in adults, there are limited techniques available for monitoring young infants. This study used near infrared spectroscopy to investigate functional activation in the social brain network of 36 five-month-old infants. We measured the hemodynamic responses to visually presented stimuli in the temporal lobes. A significant increase in oxyhemoglobin was localized to 2 posterior temporal sites bilaterally, indicating that these areas are involved in the social brain network in young infants.
在社会环境中参与和交流的能力是人类物种的决定性特征之一。虽然构成社会大脑的区域网络在成年人中已成为广泛研究的对象，但用于监测幼儿的技术有限。本研究使用近红外光谱技术来研究36名五个月大婴儿的社会大脑网络中的功能激活情况。我们测量了颞叶对视觉呈现刺激的血流动力学反应。双侧颞叶后部的2个部位氧合血红蛋白显著增加，表明这些区域参与了幼儿的社会大脑网络。
