The UNC Early Life Whole-Brain Functional Parcellation is an infant- and early-childhood-dedicated functional atlas resource spanning birth to 6 years of age. It provides age-independent and age-dependent parcellations of the cerebral cortex, cerebellum, and subcortex within a unified framework, enabling developmental studies of whole-brain functional organization and cross-structure correspondence. The release includes cortical, cerebellar, and subcortical parcellation maps, multi-resolution outputs, age-specific results, templates, label/color tables, and documentation for atlas-based fMRI and connectivity analyses.
