Differences in the extent of anatomical connections within the thalamus between sensory and association cortical parcels. (A) Resting-state functional connectivity networks identified by Ji et al. (48). (B) Average $E{D}_{pc1}$ loading within each network for each subject. Barplots show the mean and standard error. (C) Sensory networks exhibited significantly higher $E{D}_{pc1}$ loadings compared to association networks (two-sided Wilcoxon signed-rank test; $\mathrm{*}\mathrm{*}\mathrm{*}\mathrm{p}<0.001$). (D) Cortical myelin map calculated by averaging T1w/T2w values across subjects. (E) Cortical principal functional gradient ($RSF{C}_{pc1}$) loading map derived from PCA on cortico-cortical resting-state functional connectivity data. Sensory cortical parcels exhibit higher T1w/T2w values and $RSF{C}_{pc1}$ loadings compared to association cortical parcels. (F,G) Correlations between $E{D}_{pc1}$ loadings and T1w/T2w values, as well as $RSF{C}_{pc1}$ loadings, across the cortex. (H,I) On average, a moderate relationship was observed between $E{D}_{pc1}$ loadings and T1w/T2w values, as well as $RSF{C}_{pc1}$ loadings, across subjects. Boxplots show the median and inter-quartile ranges.
