Fig. 3: Principal and secondary gradients in controls.

Distribution of embedding values along the principal and secondary gradients for each canonical resting-state network in healthy controls, colour-coded according to Yeo et al., 2018 partition scheme. Below, the cortical surface is presented according to each parcel’s average embedding value along the gradients. Along the principal gradient, the sensorimotor network is anchored on one end of the spectrum in dark blue/purple (precentral and postcentral gyri) and on the opposite end lies the default-mode network in bright red (posterior cingulate cortex/precuneus, medial prefrontal cortex, inferior parietal lobule). Along the secondary gradient, the salience network is anchored on one end of the spectrum in dark blue/purple (anterior insula, anterior cingulate cortex) and on the opposite end lies the visual network in bright red (occipital lobe).
