Two [O(15)] PET studies assessed sex differences regional brain activation in the recognition of emotional stimuli. Study I revealed that the recognition of emotion in visual faces resulted in bilateral frontal activation in women, and unilateral right-sided activation in men. In study II, the complexity of the emotional face task was increased through tje addition of associated auditory emotional stimuli. Men again showed unilateral frontal activation, in this case to the left; whereas women did not show bilateral frontal activation, but showed greater limbic activity. These results suggest that when processing broader cross-modal emotional stimuli, men engage more in associative cognitive strategies while women draw more on primary emotional references.
两项[氧（15）]正电子发射断层扫描（PET）研究评估了在识别情绪刺激时大脑区域激活的性别差异。研究I表明，女性在识别视觉面部表情中的情绪时会导致双侧额叶激活，而男性则是单侧右侧激活。在研究II中，通过添加相关的听觉情绪刺激增加了情绪面部任务的复杂性。男性再次表现出单侧额叶激活，这次是左侧；而女性没有表现出双侧额叶激活，但表现出更强的边缘系统活动。这些结果表明，在处理更广泛的跨模态情绪刺激时，男性更多地采用联想认知策略，而女性更多地依赖于基本情绪参照。
