However, our study did not reveal any significant associations of the frontal EEG activity with internalizing and externalizing behaviors.

Although relative right frontal EEG asymmetry was widely reported to reflect a vulnerability to maternal depression [3], our study found that neither pre - nor early post-natal maternal depressive symptoms independently contributed to the prediction of the right frontal activity, FC, nor their asymmetry in 6 - and 18 - month infants.

Beyond frontal EEG activity, we examined the influence of prenatal and postnatal depression upon frontal functional connectivity (FC).

Neither prenatal nor postnatal maternal depressive symptoms independently predicted neither the frontal EEG activity nor functional connectivity in 6 - and 18 - month infants.

Although pre and post-natal maternal depressive symptoms did not independently predict infant frontal function, our study demonstrated a prominent association of the change of maternal depressive symptoms from the prenatal to postnatal period with right frontal EEG activity and relative right frontal EEG asymmetry in 6 - month infants, that is, increasing maternal depressive symptoms from the prenatal to postnatal period predicted greater right frontal activity and relative right frontal asymmetry amongst 6 - month infants.

Behavioral activation sensitivity and resting frontal eeg asymmetry: Covariation of putative indicators related to risk for mood disorders

Our study did not reveal any relationships between prenatal (or postnatal) maternal depression with frontal EEG activity nor frontal connectivity of infants at 6 months and 18 months of age.

However, limited research has examined the effects of congruence and incongruence between prenatal and postnatal maternal depressive symptoms on frontal EEG function and behaviors of children in the first 2 years of life.

Second, we examined whether the congruence or incongruence of maternal depressive symptoms between pregnancy and early postnatal period, represented by the change of levels of maternal depressive symptoms between pregnancy and postnatal period, influences frontal EEG activity and functional connectivity, as well as internalizing and externalizing behaviors at 24 months of age.

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.

To examine our first aim, separate regression models were used to evaluate each frontal EEG measure (dependent variable; frontal EEG power: FL, FR, and FA; functional connectivity: FL, FR, and FA), and each behavioral score (dependent variable; internalizing and externalizing score) in relation with pre - or post-natal maternal EPDS score (independent variable).

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.

For the third aim, regression analyses were conducted to examine the associations of frontal EEG at 6 and 18 months of age (independent variable) with externalizing and internalizing behavioral scores at 24 months of age (dependent variable).

Positive affect is associated with greater degrees of left compared with right superior frontal EEG activity at rest (18).

ADHD Symptoms in Post-Institutionalized Children Are Partially Mediated by Altered Frontal EEG Asymmetry.

The onset of meditation in the monks coincided with an increase in high - frequency EEG electrical activity in the so - called gamma band (spanning 25 to 42 oscillations a second), which was synchronized across the frontal and parietal cortices.

Those who woke during REM sleep and successfully recalled their dreams were more likely to demonstrate a pattern of EEG oscillations called theta waves in frontal and prefrontal cortex areas — the parts of the brain where our most advanced thinking occurs.

For example, certain biological events during early development, such as excessive androgen production, exposure to synthetic androgens, thyroid dysfunction, Cushing's disease, and congenital adrenal hyperplasia, can combine with environmental influences to predispose women to antisocial behavior.69 Additionally, EEG research has uncovered asymmetries in the frontal activation of antisocial females» brains.70 Normative males and females tend to exhibit asymmetric frontal brain activation, with boys having greater right frontal activation and girls having greater left frontal activation.

Moreover, greater - postnatal - than - prenatal maternal depressive symptoms were associated with lower right frontal FC in 18 month olds (β = -0.382, p = 0.002, df = 58), after adjusting for post-conceptual age on the EEG visit day.

However, increasing maternal depressive symptoms from the prenatal to postnatal period predicted greater right frontal activity and relative right frontal asymmetry amongst 6 - month infants but these finding were not observed amongst 18 - month infants after adjusted for post-conceptual age on the EEG visit day.

Subsequently increasing maternal depressive symptoms from the prenatal to postnatal period predicted lower right frontal connectivity within 18 - month infants but not among 6 - month infants after controlling for post-conceptual age on the EEG visit day.
