Annual Research Review: All mothers are not created equal: neural and psychobiological perspectives on mothering and the importance of individual differences / Jennifer BARRETT in Journal of Child Psychology and Psychiatry, 52-4 (April 2011)

To mother appropriately requires the action of systems that regulate sensation, perception, affect, reward, executive function, motor output and learning. When a mother is at risk to engage in less than optimal mothering, such as when she is depressed or has experienced adversity in childhood, the function of many or all of maternal and related systems may be affected. In this paper, we will review what is currently known about the biological basis of mothering, with attention to literature on hormones but with a particular focus on recent advances in the fields of functional neuroimaging. Instead of discussing strictly ‘maternal’ brain imaging studies, we instead use a systems approach to survey important findings relevant to brain systems integral to and/or strongly related to the mothering experience: (a) social behavior; (b) reward and affect; (c) executive function; and (d) maternal behavior. We find that there are many commonalities in terms of the brain regions identified across these systems and, as we would expect, all are sensitive to the influence of, or function differently in the context of, depression and adverse early experience. It is likely that the similarity and cross-talk between maternal, affect and stress systems, observed behaviorally, hormonally and in the context of brain function, allows for mood disturbance and early adverse experiences to have a significant impact on the quality of mothering and the motivation to mother.

Using cross-species comparisons and a neurobiological framework to understand early social deprivation effects on behavioral development / Zoë H. BRETT in Development and Psychopathology, 27-2 (May 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-2 (May 2015) . - p.347-367 Titre : Using cross-species comparisons and a neurobiological framework to understand early social deprivation effects on behavioral development Type de document : Texte imprimé et/ou numérique Auteurs : Zoë H. BRETT, Auteur ; Kathryn L. HUMPHREYS, Auteur ; Alison S. FLEMING, Auteur ; Gary W. KRAEMER, Auteur ; Stacy S. DRURY, Auteur Article en page(s) : p.347-367 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Building upon the transactional model of brain development, we explore the impact of early maternal deprivation on neural development and plasticity in three neural systems: hyperactivity/impulsivity, executive function, and hypothalamic–pituitary–adrenal axis functioning across rodent, nonhuman primate, and human studies. Recognizing the complexity of early maternal–infant interactions, we limit our cross-species comparisons to data from rodent models of artificial rearing, nonhuman primate studies of peer rearing, and the relations between these two experimental approaches and human studies of children exposed to the early severe psychosocial deprivation associated with institutional care. In addition to discussing the strengths and limitations of these paradigms, we present the current state of research on the neurobiological impact of early maternal deprivation and the evidence of sensitive periods, noting methodological challenges. Integrating data across preclinical animal models and human studies, we speculate about the underlying biological mechanisms; the differential impact of deprivation due to temporal factors including onset, offset, and duration of the exposure; and the possibility and consequences of reopening of sensitive periods during adolescence.
