These studies have suggested that infants born to prenatally depressed mothers had greater right frontal
EEG asymmetry than those born to non-depressed mothers [10, 12].
When including prenatally and postnatally depressed mothers with middle and upper SES, Lusby et al. (2014) found no association between postnatal depressive symptoms and the frontal
EEG asymmetry at 3 - and 6 - month infants after adjusting for prenatal maternal depression [12].
Furthermore, a few longitudinal studies have examined the postnatal maternal depression trajectory in relation to children's frontal
EEG asymmetry and behaviors from 14 months to 6.5 years [20] and to children's social skill from 1 to 36 months [23].
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.
Infant frontal
EEG asymmetry in relation with postnatal maternal depression and parenting behavior.
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.

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

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.
Several investigations reported minor differences in ERPs functioning, including longer latencies at the P3 site, 57 longer latencies of certain waves for brainstem auditory - evoked potentials, 58 more slow waves and fewer α - waves, 59 and
asymmetry in peak amplitude evoked - response potentials.10 These findings are variable and do not provide any compelling evidence for a particular
EEG pattern for patients with ADHD.
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.
Although most of studies focused on either prenatal or postnatal maternal depression, they have reached a consensus, that is, that greater relative right frontal electroencephalogram (
EEG)
asymmetry has been suggested to be a neural basis reflecting a vulnerability of offspring to maternal depression [3, 7, 8].
After adjusting for post-conceptual age on the
EEG visit day, greater - postnatal - than - prenatal maternal depressive symptoms were significantly associated with greater right frontal activity (Table 2, Fig 2b) and greater relative right frontal
asymmetry in infants at 6 months of age (Table 2, Fig 2c).
Neither prenatal nor postnatal EPDS scores independently associated with bilateral functional connectivity and its
asymmetry in 6 - month and 18 - month - old infants, after adjusting for post-conceptual age on the
EEG visit day (Table 2).
Severity of maternal depressive symptoms was not associated with bilateral functional connectivity and its
asymmetry in 6 - month and 18 - month - old infants, after adjusting for post-conceptual age on the
EEG visit day (Table 2).
Briefly, in the female sample, greater - postnatal - than - prenatal maternal depressive symptoms were significantly associated with greater right frontal activity (β = -0.262, p = 0.020, df = 72) and greater relative right frontal
asymmetry in infants at 6 months of age (β = -0.426, p < 0.001, df = 72) after adjusting for post-conceptual age on the
EEG visit day.
Adjusted for post-conceptual age on the
EEG visit day, regression analysis did not reveal an association of prenatal or postnatal EPDS with the bilateral frontal activity and its
asymmetry in 6 - month and 18 - month - old infants (Table 2).
