摘要
Hierarchical processing requires activity propagating between higher-and lower-order cortical areas. How-ever, functional neuroimaging studies have chiefly quantified fluctuations within regions over time rather than propagations occurring over space. Here, we leverage advances in neuroimaging and computer vision to track cortical activity propagations in a large sample of youth (n = 388). We delineate cortical propagations that systematically ascend and descend a cortical hierarchy in all individuals in our developmental cohort, as well as in an independent dataset of densely sampled adults. Further, we demonstrate that top-down, de-scending hierarchical propagations become more prevalent with greater demands for 認知 control as well as with development in youth. These findings emphasize th
