Maternal neglect and the serotonin system are associated with daytime sleep in infant rhesus monkeys / Alexander BAXTER in Development and Psychopathology, 32-1 (February 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-1 (February 2020) . - p.1-10 Titre : Maternal neglect and the serotonin system are associated with daytime sleep in infant rhesus monkeys Type de document : Texte imprimé et/ou numérique Auteurs : Alexander BAXTER, Auteur ; Elizabeth K. WOOD, Auteur ; Christina S. BARR, Auteur ; Daniel B. KAY, Auteur ; Stephen J. SUOMI, Auteur ; J. Dee HIGLEY, Auteur Article en page(s) : p.1-10 Langues : Anglais (eng) Mots-clés : 5-hydroxyindoleacetic acid  development  infant sleep  maternal neglect  serotonin transporter gene Index. décimale : PER Périodiques Résumé : Environmental and biological factors contribute to sleep development during infancy. Parenting plays a particularly important role in modulating infant sleep, potentially via the serotonin system, which is itself involved in regulating infant sleep. We hypothesized that maternal neglect and serotonin system dysregulation would be associated with daytime sleep in infant rhesus monkeys. Subjects were nursery-reared infant rhesus macaques (n = 287). During the first month of life, daytime sleep-wake states were rated bihourly (0800-2100). Infants were considered neglected (n = 16) if before nursery-rearing, their mother repeatedly failed to retrieve them. Serotonin transporter genotype and concentrations of cerebrospinal fluid 5-hydroxyindoleacetic acid (5-HIAA) were used as markers of central serotonin system functioning. t tests showed that neglected infants were observed sleeping less frequently, weighed less, and had higher 5-HIAA than non-neglected nursery-reared infants. Regression revealed that serotonin transporter genotype moderated the relationship between 5-HIAA and daytime sleep: in subjects possessing the Ls genotype, there was a positive correlation between 5-HIAA and daytime sleep, whereas in subjects possessing the LL genotype there was no association. These results highlight the pivotal roles that parents and the serotonin system play in sleep development. Daytime sleep alterations observed in neglected infants may partially derive from serotonin system dysregulation.

Neglectful maternal caregiving involves altered brain volume in empathy-related areas / María José RODRIGO in Development and Psychopathology, 32-4 (October 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-4 (October 2020) . - p.1534-1543 Titre : Neglectful maternal caregiving involves altered brain volume in empathy-related areas Type de document : Texte imprimé et/ou numérique Auteurs : María José RODRIGO, Auteur ; Inmaculada LEON, Auteur ; Lorna GARCÍA-PENTÓN, Auteur ; Juan Andrés HERNÁNDEZ-CABRERA, Auteur ; Ileana QUINONES, Auteur Article en page(s) : p.1534-1543 Langues : Anglais (eng) Mots-clés : empathy  maternal neglect  mother–child interaction  volume alterations  voxel-based morphometry Index. décimale : PER Périodiques Résumé : The maternal brain undergoes adaptations to sensitive caregiving that are critical for infant well-being. We investigated structural alterations associated with neglectful caregiving and their effects on mother-child interactive behavior. High-resolution 3D volumetric images were obtained on 25 neglectful (NM) and 23 non-neglectful control (CM) mothers. Using voxel-based morphometry, we compared differences in gray and white matter (GM and WM, respectively) volume. Mothers completed an empathy scale and participated with their children in a play task (Emotional Availability Scale, EA). Neglectful mothers showed smaller GM volume in the right insula, anterior/middle cingulate (ACC/MCC), and right inferior frontal gyrus and less WM volume in bilateral frontal regions than did CM. A greater GM volume was observed in the right fusiform and cerebellum in NM than in CM. Regression analyses showed a negative effect of greater fusiform GM volume and a positive effect of greater right frontal WM volume on EA. Mediation analyses showed the role of emotional empathy in the positive effect of the insula and right inferior frontal gyrus and in the negative effect of the cerebellum on EA. Neglectful mothering involves alterations in emotional empathy-related areas and in frontal areas associated with poor mother-child interactive bonding, indicating how critical these areas are for sensitive caregiving.
