(a) Nine large-scale brain networks. 213 cortical ROIs were defined in previous study²⁹,³⁰, and are categorised into nine brain networks. No ROI was shared between different networks. (b) Analysis procedures. We first extracted grey matter volume (GMV) for each ROI from preprocessed anatomical neuroimaging data, and then classified the ROIs to the nine networks (panel a). After calculating average GMV for each network, we normalised the GMVs and estimated relative GMVs (rGMVs) for the networks. This procedure was repeated for each participant.
