两项 [O-15] PET 研究评估了识别情绪刺激时大脑区域激活的性别差异。研究一表明，对视觉面孔中情绪的识别会导致女性的双侧额叶激活，以及男性的单侧右侧额叶激活。在研究二中，通过添加相关的听觉情感刺激，增加了情感面部任务的复杂性。男性再次表现出单侧额叶激活，在本例中为左侧；而女性则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式情感刺激时，男性更多地参与联想认知策略，而女性更多地利用主要情感参考。
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 cofnitive strategies while women draw more on primary emotional references.
