This study investigates the neurodevelopmental trajectories of the human cerebral cortex using longitudinal neuroimaging data from 375 typically developing children and young adults. The researchers examined cortical thickness at over 40,000 points across the cerebrum, capturing both columnar architecture and developmental changes. They found that cortical regions with simpler laminar architecture, such as most limbic areas, show simpler growth trajectories, while polysensory and high-order association areas, which have more complex laminar architecture, exhibit more complex developmental trajectories. The study also documented the dynamic maturation of the cerebral cortex through time-lapse sequences, revealing that primary sensory areas reach peak cortical thickness earlier than polymodal association areas. The findings align with traditional cytoarchitectonic maps, suggesting that cortical development is influenced by both environmental and genetic factors. The study supports the idea that the organization of the cerebral cortex can be understood in terms of a series of concentric rings, with isocortex at the core, allocortex at the periphery, and transitional areas in between.This study investigates the neurodevelopmental trajectories of the human cerebral cortex using longitudinal neuroimaging data from 375 typically developing children and young adults.
