(Top) Group-level average functional connectivity matrices organized based on their modular distributions (DMN = red, DMN2 = magenta, SN = blue, ECN/VAN = green, ECN = cyan, and SMN = yellow). (Bottom) Brain functional connectivity pattern color-coded anatomical representation for the four participant groups.
Abbreviations: CN, cognitively normal; LLD, late-life depression; aMCI, amnestic mild cognitive impairment; aMCI-LLD, late-life depression comorbid with amnestic mild cognitive impairment; DMN: default mode network, SN: salience network, ECN: executive control network, VAN: visual attention network, SMN: sensory motor network.
