Interacting with the environment to process sensory information, generate perceptions, and shape goal-directed behavior engages neural networks in brain areas with highly varied representations, ranging from unimodal sensory cortices to higher-order association areas. These networks form and undergo considerable and potentially area-specific refinement over development. However, recent work suggests a much greater degree of commonality in the functional organization of networks across such diverse cortical areas during early development. It is currently unknown whether this initially common st
