598-从童年到成年大脑动态时空传播的发育演变

from 聊聊Sci

这项神经科学研究利用复杂主成分分析(CPCA)揭示了人类从童年到成年早期大脑动态信号传播的演变规律。研究人员识别出三大主要传播轴:感觉-结合(S-A)、任务正向-默认网络(TP-D)以及躯体运动-视觉(SM-V)。结果显示,随着年龄增长,大脑在S-A和TP-D状态下停留的时间显著增加,而在SM-V状态下的时间则有所减少,反映出功能组织向成年模式的演进。特别值得注意的是,“自上而下”的信号传播随发育增强,且比“自下而上”的模式更能有效预测个体的认知能力。通过在多个独立数据集上的验证,该研究证明了瞬间神经动态的成熟是支持青少年时期认知功能发展的核心机制。References: Byeon K, Park H, Park S, et al.
