在生命的第一年，母亲和婴儿之间的交流和沟通完全是言语前的，是基于母亲理解婴儿的需要和感受的能力（即移情）和模仿婴儿的面部表情；这促进了影响婴儿自我发展的社会对话。16位母亲在观察和模仿自己孩子和别人孩子的脸时，接受了功能性磁共振成像。我们发现，镜像神经元系统、脑岛和杏仁核在情绪表达时更加活跃，当与自己的孩子互动时，这个回路的参与程度更大，而且它与母亲的反射功能（一种同理心的衡量标准）相关。我们还发现，通过对单个情绪进行比较，快乐的表达主要在右侧边缘和旁边缘区域引起反应；相比之下，模棱两可的表达引起了左高阶认知和运动区域的反应，这可能反映了认知努力。
During the first year of life, exchanges and communication between a mother and her infant are exclusively preverbal and are based on the mother's ability to understand her infant's needs and feelings (i.e., empathy) and on imitation of the infant's facial expressions; this promotes a social dialog that influences the development of the infant self. Sixteen mothers underwent functional magnetic resonance imaging while observing and imitating faces of their own child and those of someone else's child. We found that the mirror neuron system, the insula and amygdala were more active during emotional expressions, that this circuit is engaged to a greater extent when interacting with one's own child, and that it is correlated with maternal reflective function (a measure of empathy). We also found, by comparing single emotions with each other, that joy expressions evoked a response mainly in right limbic and paralimbic areas; by contrast, ambiguous expressions elicited a response in left high order cognitive and motor areas, which might reflect cognitive effort.
