Developmental brain sciences toward understanding of origin of intelligence

婴儿早期的大脑自发活动和身体运动的动态特征被认为是限制认知发展的因素。我们用近红外光谱技术揭示了大脑中与视听和语言加工有关的功能区域和网络的发育过程。我们还证明了认知行为的变化是通过自发运动出现的。我们进一步证明了早期自发运动与后期发育结果之间的关系。这些发现有助于理解发展问题，如特定领域与一般，在多个时间尺度上的变化和前瞻性的出现。

Dynamic features of spontaneous activity of the brain and body movements in early infancy are considered to constrain the cognitive development. We revealed the developmental processes for functional regions and networks of the brain in relation to audio-visual and language processing by using NIRS imaging. We also demonstrated that cognitive behavioral changes emerge through spontaneous movements. We further showed the evidence of the relationship between early spontaneous movements and later developmental outcomes. These findings contribute to understand the developmental issues such as domain-specific vs. general, changes over multiple time scales and emergence of prospectiveness.
