In line with previous research on the disadvantage of the incongruence of prenatal and postnatal environments on early child development [25], we hypothesized that children whose mothers had elevated postnatal maternal depressive symptoms when compared to that during pregnancy may show greater atypical frontal EEG activity and frontal functional connectivity and greater internalizing and externalizing behavioral problems.

Although many studies have examined the relationship between maternal depressive symptoms and frontal EEG activity, less research has examined how the fluctuation of maternal depressive symptoms between pre - and early post-natal period is related to frontal EEG activity.
