Dysfunctional interactions between the default mode network and the dorsal attention network in subtypes of amnestic mild cognitive impairment

Figure 5. The relationship between cognitive performance and the altered anticorrelations between the DMN and DAN across the aMCI-s and NC groups. The connectivity strengths between the left PCC and left inferior precentral sulcus had correlations with the TMT scores, the MMSE scores and the MoCa scores. Brain maps of representative slices of related areas are also showed in the figure and colored dots represent their locations. Arrows are for illustrating purpose and do not imply directionality. Abbreviations: DMN: default mode network; DAN: dorsal attention network; PCC: posterior cingulate cortex; TMT: Trail-Making Test; MMSE: Mini-Mental State Examination; MoCa: Montreal Cognitive Assessment; aMCI-s: single-domain of amnestic mild cognitive impairment; NC: normal controls.
