Abnormalities of electroencephalography microstates in patients with depression and their association with cognitive function

Figure 1 Illustrates a comparison of scalp topographies between the depression group and healthy control group. According to previous literature, microstates are represented by the classes A to D. DEP: Depression group; CON: Healthy control group.

Figure 2 Bar diagrams show the parameters of each microstate of the two groups. A: Duration; B: Occurrence; C: contribution. Horizontal coordinate axis represents four microstates A, B, C, and D; D: Transition probability; horizontal coordinate axis represents microstate transition type. ^aP < 0.05; ^cP < 0.001. DEP: Depression group; CON: Healthy control group; NS: Not significant.

Figure 3 Correlation between the repeatable battery for the assessment of neuropsychological status visuospatial/constructional function scores and transition probability microstate class C to class B in the depression group. P values were generated by permutation tests with 100000 replicates.
