Fig. 4: Elastic net coefficients for predicting age from aperiodic exponents.
From: Aperiodic parameters of the fMRI power spectrum associate with preterm birth and neonatal age
Mean elastic net regression coefficients over cross-validation folds for predicting age variables in term-born participants using aperiodic exponent parameters, mapped onto cortical and subcortical regions defined by the Automated Anatomical Labeling (AAL90) atlas. Color gradient indicates the magnitude of coefficients (red = larger, blue = smaller). A Prediction of postnatal age using exponents (N = 483). B Prediction of postmenstrual age using exponents (N = 483).
