面孔的吸引力是一个非常显着的社会信号，影响择偶和其他社会判断。在这项研究中，我们使用事件相关的功能磁共振成像（fMRI）来研究对有吸引力的面孔做出反应的大脑区域，这些面孔表现出中性或轻微快乐的面部表情。有吸引力的面孔会激活内侧眶额皮层（OFC），该区域涉及代表刺激奖励价值。微笑的面部表情进一步增强了该区域的反应，这表明由内侧 OFC 活动索引的有吸引力的面孔的奖励值是由感知者定向的微笑调节的。 (C) 2002 Elsevier Science Ltd. 保留所有权利。
The attractiveness of a face is a highly salient social signal, influencing mate choice and other social judgements. In this study, we used event-related functional magnetic resonance imaging (fMRI) to investigate brain regions that respond to attractive faces which manifested either a neutral or mildly happy face expression. Attractive faces produced activation of medial orbitofrontal cortex (OFC), a region involved in representing stimulus-reward value. Responses in this region were further enhanced by a smiling facial expression, suggesting that the reward value of an attractive face as indexed by medial OFC activity is modulated by a perceiver directed smile.
