先前的研究表明，在合作交换过程中，合作伙伴之间的大脑活动是同步的。这种神经同步是否取决于伴侣的性别（即，与参与者相反或相同）是开放的以供探索。在目前的研究中，我们使用基于超扫描的功能近红外光谱（fNIRS）来研究两人游戏（女性-女性，女性-男性和男性-男性）中的合作，同时分析脑与脑的相互作用。合作是更大的男性对比女性对，中间合作水平的女性对男性。更重要的是，在与异性伴侣（女性-男性对）的二人组中，我们发现额叶区域（即，额极皮层、眶额皮层和左背外侧前额叶皮层），而同性别配对（女性-女性配对和男性-男性配对）中的合作与这种同步无关。此外，只有在混合性别的二人组中，这种跨任务块的脑间一致性的变化与合作程度的变化显着相关。这些研究结果表明，不同的神经过程之间的合作的混合性别和同性的二元互动。《脑地图》36：2039-2048，2015年。(c)2015 Wiley Periodicals，Inc.
Previous studies have shown that brain activity between partners is synchronized during cooperative exchange. Whether this neural synchronization depends on the gender of partner (i.e., opposite or same to the participant) is open to be explored. In current study, we used functional near-infrared spectroscopy (fNIRS) based hyperscanning to study cooperation in a two-person game (female-female, female-male, and male-male) while assaying brain-to-brain interactions. Cooperation was greater in male-male pairs than in female-female pairs, with intermediate cooperation levels for female-male pairs. More importantly, in dyads with partners with opposite gender (female-male pairs), we found significant task-related cross-brain coherence in frontal regions (i.e., frontopolar cortex, orbitofrontal cortex, and left dorsolateral prefrontal cortex) whereas the cooperation in same gender dyads (female-female pairs and male-male pairs) was not associated with such synchronization. Moreover, the changes of such interbrain coherence across task blocks were significantly correlated with change in degree of cooperation only in mixed-sex dyads. These findings suggested that different neural processes underlie cooperation between mixed-sex and same-sex dyadic interactions. Hum Brain Mapp 36:2039-2048, 2015. (c) 2015 Wiley Periodicals, Inc.
