摘要

Prior work has shown that there is substantial interindividual variation in the spatial distribution of functional 網絡s across the cerebral cortex, or functional topography. However, it remains unknown whether there are sex differences in the topography of individualized 網絡s in youth. Here we leveraged an advanced 機器學習 method (sparsity-regularized nonnegative matrix factorization) to define individualized functional 網絡s in 693 youth (ages 8-23 years) who underwent functional magnetic resonance imaging as part of the Philadelphia Neurodevelopmental Cohort. Multivariate pattern analysis using support vector machines classified participant sex based on functional topography with 83% accuracy (p<0.0001). 大腦 regions most effective in classifying participant sex belonged to association 網絡s, inclu
