Infants' neural responses to emotional faces are related to maternal anxiety / L. C. BOWMAN in Journal of Child Psychology and Psychiatry, 63-2 (February 2022)
[article]
Titre : Infants' neural responses to emotional faces are related to maternal anxiety Type de document : Texte imprimé et/ou numérique Auteurs : L. C. BOWMAN, Auteur ; S. A. MCCORMICK, Auteur ; Finola KANE-GRADE, Auteur ; W. XIE, Auteur ; Michelle BOSQUET ENLOW, Auteur ; C. A. NELSON, Auteur Article en page(s) : p.152-164 Langues : Anglais (eng) Mots-clés : Eeg/erp Maternal anxiety N290 Nc P400 emotions faces infants Index. décimale : PER Périodiques Résumé : BACKGROUND: Postnatal maternal anxiety is common (estimates as high as 40% prevalence) and is associated with altered mother-infant interactions (e.g., reduced maternal emotional expression and engagement). Neural circuitry supporting infants' face and emotion processing develops in their first year. Thus, early exposure to maternal anxiety may impact infants' developing understanding of emotional displays. We examine whether maternal anxiety is associated with individual differences in typically developing infants' neural responses to emotional faces. METHODS: One hundred and forty two mother-infant dyads were assessed when infants were 5, 7, or 12?months old. Infants' electroencephalographic (EEG) data were recorded while passively viewing female happy, fearful, and angry faces. Three event-related potential (ERP) components, each linked to face and emotion processing, were evaluated: NC, N290, and P400. Infant ERP amplitude was related to concurrent maternal-report anxiety assessed with the Spielberger State-Trait Anxiety Inventory (Trait form). RESULTS: Greater maternal anxiety predicted more negative NC amplitude for happy and fearful faces in left and mid-central scalp regions, beyond covarying influences of maternal depression symptoms, infant negative emotionality, and infant age. CONCLUSIONS: Postnatal maternal anxiety is related to infants' neural processing of emotional expressions. Infants of mothers endorsing high trait anxiety may need additional attentional resources to process happy and fearful faces (expressions less likely experienced in mother-infant interactions). Future research should investigate mechanisms underlying this association, given possibilities include experiential, genetic, and prenatal factors.

Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Estrogen receptor beta Lipid metabolism Mitochondria Oxidative stress Progestin Resveratrol Index. décimale : PER Périodiques Résumé : Background: Recent literatures indicate that maternal hormone exposure is a risk factor for autism spectrum disorder (ASD). We hypothesize that prenatal progestin exposure may counteract the neuroprotective effect of estrogen and contribute to ASD development, and we aim to develop a method to ameliorate prenatal progestin exposure-induced autism-like behavior. Methods: Experiment 1: Prenatal progestin exposure-induced offspring are treated with resveratrol (RSV) through either prenatal or postnatal exposure and then used for autism-like behavior testing and other biomedical analyses. Experiment 2: Prenatal norethindrone (NET) exposure-induced offspring are treated with ERbeta knockdown lentivirus together with RSV for further testing. Experiment 3: Pregnant dams are treated with prenatal NET exposure together with RSV, and the offspring are used for further testing. Results: Eight kinds of clinically relevant progestins were used for prenatal exposure in pregnant dams, and the offspring showed decreased ERbeta expression in the amygdala with autism-like behavior. Oral administration of either postnatal or prenatal RSV treatment significantly reversed this effect with ERbeta activation and ameliorated autism-like behavior. Further investigation showed that RSV activates ERbeta and its target genes by demethylation of DNA and histone on the ERbeta promoter, and then minimizes progestin-induced oxidative stress as well as the dysfunction of mitochondria and lipid metabolism in the brain, subsequently ameliorating autism-like behavior. Conclusions: We conclude that resveratrol ameliorates prenatal progestin exposure-induced autism-like behavior through ERbeta activation. Our data suggest that prenatal progestin exposure is a strong risk factor for autism-like behavior. Many potential clinical progestin applications, including oral contraceptive pills, preterm birth drugs, and progestin-contaminated drinking water or seafood, may be risk factors for ASD. In addition, RSV may be a good candidate for clinically rescuing or preventing ASD symptoms in humans, while high doses of resveratrol used in the animals may be a potential limitation for human application.
