Fig. 3

A Hierarchical clustering dendrogram of the 12 functional marmoset components using squared Euclidean distance and Ward’s linkage. Colors indicate functional clusters: multisensory (red), somatomotor (green), visual-default (turquoise), and subcortical-motor (purple). B Within-species correlation matrix showing pairwise temporal correlations (Pearson’s r) between component timecourses. Components are ordered based on the sequence specified by the hierarchical clustering tree. Networks within the same functional group show strong positive correlations, while cross-cluster relationships are more variable, including anticorrelations between somatomotor and multisensory networks. Clusters identified through hierarchical clustering are highlighted on the matrices with colored squares, following the same color scheme presented in panel A. Red shades indicate positive correlations, while blue shades represent negative correlations. Only correlations with an absolute r value greater than 0.10 are displayed.
