与嫉妒有关的行为，如亲密伴侣暴力和病态嫉妒，在男性中更为常见。主要的问卷调查研究表明，男性和女性有不同的模块来处理性和情感不忠的线索。我们的目的是利用功能性磁共振成像来阐明男性和女性对描述性和情感不忠的句子的神经反应。尽管在对性和情感不忠的嫉妒的自评得分上没有性别差异，但男性和女性在对这两种不忠的反应中表现出不同的大脑激活模式。在嫉妒的情况下，男性比女性在涉及性/攻击性行为的大脑区域，如杏仁核和下丘脑，表现出更大的激活。相反，女性在颞后上沟表现出更大的激活。我们的功能磁共振成像结果支持这样的观点，即男性和女性有不同的神经心理模块来处理性和情感上的不忠。我们的发现可能有助于更好地理解主要在男性中观察到的与嫉妒相关的行为的神经基础。
Jealousy-related behaviors such as intimate partner violence and morbid jealousy are more common in males. Principal questionnaire studies suggest that men and women have different modules to process cues of sexual and emotional infidelity. We aimed to elucidate the neural response to sentences depicting sexual and emotional infidelity in men and women using functional magnetic resonance imaging. Although there was no sex difference in the self-rating score of jealousy for sexual and emotional infidelity, men and women showed different brain activation patterns in response to the two types of infidelity. During jealous conditions, men demonstrated greater activation than women in the brain regions involved in sexual/aggressive behaviors such as the amygdala and hypothalamus. In contrast, women demonstrated greater activation in the posterior superior temporal sulcus. Our fMRI results are in favor of the notion that men and women have different neuropsychological modules to process sexual and emotional infidelity. Our findings might contribute to a better understanding of the neural basis of the jealousy-related behaviors predominantly observed in males.
