人类的育儿大脑网络调节照顾行为。当受到婴儿的刺激时，与非父母相比，父亲和母亲都表现出不同的神经激活模式。与女性相比，人类男性在怀孕期间没有经历强烈的生理变化，因此父系大脑网络何时以及如何开始形成尚不清楚。因此，我们使用功能性核磁共振成像（functional MRI）检查了两组人在观看婴儿互动视频时的大脑活动反应，一组是没有孩子的男性，另一组是在伴侣的外表开始发生显著变化之前第一次当爸爸的男性。多体素模式分析显示，在怀孕早期，准爸爸的左前脑岛和额下回对亲子关系的反应出现了早期的变化。此外，这些变化与父亲的一些特征有关，比如对养育子女的负面形象。这些外部因素可能会在怀孕早期影响父亲大脑的发育。
The human parenting brain network mediates caregiving behaviors. When exposed to the stimuli of their infants, compared with non-parents, both fathers and mothers exhibit distinct patterns of neural activation. As human males, relative to females, do not undergo robust physiological changes during pregnancy, when and how the paternal brain networks begin to form remains unclear. Thus, using functional MRI, we examined brain activation in response to infant-interaction videos in two groups, childless males and first-time expectant fathers during their partners' early pregnancy before remarkable changes in their partners' appearances commenced. Multivoxel pattern analysis revealed that expectant fathers' left anterior insula and inferior frontal gyrus showed incipient changes in response to parenthood during early pregnancy. Furthermore, these changes were associated with several paternal traits, such as a negative image toward parenting. Such external factors might influence the paternal brain's development during early pregnancy.
