Figure 6.

The relative power of the theta band at the left frontal site (F7) during the eyes-closed resting state was positively correlated with the mean amplitudes of the nonmatch-related P300 effect (nonmatch minus match) in the left frontal region (500–800 milliseconds) during working memory retrieval across all older adults with age, sex, and education as covariates. Notes: Data of the Control group are colored in purple and those of the SCD group are colored in blue. The yellow fit line displays the relationship between the theta power and nonmatch-related P300 effect for all older adults. The shaded area represents a 95% confidence interval. SCD = subjective cognitive decline.
