Adults with histories of childhood maltreatment (CM) are more likely to display problematic parenting behaviors. The goal of this study was to examine changes in maternal brain activation to negative infant cues over the early postpartum period among new mothers with and without histories of CM, as this is a period of immense neuroplasticity in the maternal brain. CM was measured using the Adverse Childhood Experiences Scale. Functional magnetic resonance imaging (fMRI) conducted at approximately 5 and 13 weeks postpartum measured brain responses to own and unfamiliar infant cues in primiparous women. Women with histories of CM displayed increasing activation in the anterior cingulate cortex, and greater increases in anterior cingulate cortex activation was associated with maternal reports of less regulatory capacity in their infants. Preliminary results suggest that new mothers with CM histories display greater brain responses to negative infant cues compared to new mothers without CM histories. Women with CM histories may benefit from additional supports during the transition to parenthood.
有童年虐待史（CM）的成年人更有可能表现出有问题的养育行为。本研究的目的是调查有和没有CM病史的初产妇在产后早期对负面婴儿线索的母亲大脑激活变化，因为这是母亲大脑具有巨大神经可塑性的时期。使用儿童期不良经历量表测量CM。在产后约5周和13周进行的功能磁共振成像（fMRI）测量了初产妇对自己和陌生婴儿线索的大脑反应。有CM病史的女性在前扣带回皮层的激活增加，前扣带回皮层激活的更大增加与母亲报告的对婴儿调节能力较差有关。初步结果表明，与没有CM病史的初产妇相比，有CM病史的初产妇对负面婴儿线索的大脑反应更大。有CM病史的女性在向为人父母的过渡过程中可能会从额外的支持中受益。
