研究指出母乳喂养对于促进母婴密切接触和社会情感发展的重要性。最近的功能性磁共振成像（fMRI）研究已经确定了与母亲行为相关的大脑区域。然而，很少有研究已经解决了人类母亲母乳喂养和母亲行为之间的关系的神经生物学机制。我们调查了母乳喂养，母亲的大脑对自己的婴儿刺激的反应，和母亲在产后早期的敏感性之间的关联。17名健康婴儿的生物学母亲在产后2-4周根据喂养方法-纯母乳喂养和纯配方奶粉喂养参与了两个配对组。在产后的第一个月进行了功能性磁共振成像扫描，以检查母亲对自己婴儿的哭声与控制婴儿哭声的大脑激活。产后3-4个月母亲和婴儿之间的二元互动在家中录像，并对母亲的敏感性进行盲编码。在产后的第一个月，母乳喂养的母亲在听自己的婴儿哭声时，与配方奶粉喂养的母亲相比，上级额回、前额叶、楔前叶、纹状体和杏仁核的激活程度更高。对于母乳喂养和配方奶粉喂养的母亲，右侧上级额回和杏仁核的激活程度越高，产后3-4个月时母亲的敏感性越高。研究结果表明，母乳喂养和婴儿在产后早期对母婴联系和同理心的大脑区域的暗示做出更大反应之间存在联系。当婴儿进入他们的社会世界时，这种大脑激活可能会促进母亲更大的敏感性。
Research points to the importance of breastfeeding for promoting close mother-infant contact and social-emotional development. Recent functional magnetic resonance imaging (fMRI) studies have identified brain regions related to maternal behaviors. However, little research has addressed the neurobiological mechanisms underlying the relationship between breastfeeding and maternal behavior in human mothers. We investigated the associations between breastfeeding, maternal brain response to own infant stimuli, and maternal sensitivity in the early postpartum. Seventeen biological mothers of healthy infants participated in two matched groups according to feeding method – exclusive breastfeeding and exclusive formula-feeding at 2-4 weeks postpartum. fMRI scanning was conducted in the first postpartum month to examine maternal brain activation in response to her own baby's cry versus control baby-cry. Dyadic interactions between mothers and infants at 3-4 months postpartum were videotaped in the home and blindly coded for maternal sensitivity. In the first postpartum month, breastfeeding mothers showed greater activations in the superior frontal gyrus, insula, precuneus, striatum, and amygdala while listening to their own baby-cry as compared to formula-feeding mothers. For both breastfeeding and formula-feeding mothers, greater activations in the right superior frontal gyrus and amygdala were associated with higher maternal sensitivity at 3-4 months postpartum. Results suggest links between breastfeeding and greater response to infant cues in brain regions implicated in maternal-infant bonding and empathy during the early postpartum. Such brain activations may facilitate greater maternal sensitivity as infants enter their social world.
