Figure 3. Anticorrelations between the DMN and DAN among the four groups. (A) The left PCC seed (red color) showing anticorrelations with the DAN (cool colors) among the four groups; (B) The left mPFC seed (red color) showing anticorrelations with the DAN (cool colors) among the four groups; (C) The left IPS seed (red color) showing anticorrelations with the DMN (cool colors) among the four groups; (D) The left FEF seed (red color) showing anticorrelations with the DMN (cool colors) among the four groups. P < 0.05, cluster level FWE corrected. Abbreviations: DMN: default mode network; DAN: dorsal attention network; PCC: posterior cingulate cortex; IPS: intraparietal sulcus; FEF: frontal eye fields; mPFC: medial prefrontal cortex; AD: Alzheimer's disease; aMCI-s: single-domain of amnestic mild cognitive impairment; aMCI-m: multiple-domain of amnestic mild cognitive impairment; NC: normal controls.
