母亲会被婴儿各种不同形式的暗示所吸引。为了阐明母亲被婴儿气味吸引的可能神经机制，我们使用近红外光谱检测了19只母亲和19只未生育的雌性（非母亲）在气味检测任务中的前额叶皮质（PFC）活动。他们被要求在每项任务中判断自己是否闻到了气味。我们通过测量相对血红蛋白（oxyHb）浓度来估计PFC的活性。结果表明，在检测婴儿气味时，母亲的双侧PFC活动增加，而非母亲的则没有。相比之下，成年男性的气味在母亲和非母亲身上激活的PFC相似。这些发现表明，母亲对婴儿气味的反应中PFC的激活解释了母亲对婴儿气味吸引的部分神经机制。
Mothers are attracted by infant cues of a variety of different modalities. To clarify the possible neural mechanisms underlying maternal attraction to infant odor cues, we used near-infrared spectroscopy to examine prefrontal cortex (PFC) activity during odor detection tasks in which 19 mothers and 19 nulliparous females (nonmothers) were presented with infant or adult male odors. They were instructed to make a judgment about whether they smelled an odor during each task. We estimated the PFC activity by measuring the relative oxyhemoglobin (oxyHb) concentrations. The results showed that while detecting the infant odors, bilateral PFC activities were increased in mothers but not in nonmothers. In contrast, adult male odors activated the PFC similarly in mothers and nonmothers. These findings suggest that maternal activation of the PFC in response to infant odors explains a part of the neural mechanisms for maternal attraction to infant odors.
