关于认知与情绪关系的一个基本问题涉及情绪自我调节的神经基质。为了解决这个问题，研究人员测量了正常男性受试者的大脑活动，他们要么以正常的方式对色情电影片段做出反应，要么自愿抑制因观看色情刺激而引起的性唤起。结果表明，观看色情电影时的性唤起与“边缘”和旁边缘结构（如右侧杏仁核、右侧颞前极和下丘脑）的激活有关。此外，试图抑制因观看色情刺激而产生的性唤起与右侧额上回和右侧前扣带回的激活有关。大脑边缘区域没有被激活。这些发现强化了情绪自我调节通常是由包括各种前额叶区域和皮层下边缘结构的神经回路实现的观点。他们还认为，人类有能力通过自愿改变在心理空间中展开的思维过程的性质来影响大脑的电化学动力学。
A fundamental question about the relationship between cognition and emotion concerns the neural substrate underlying emotional self-regulation. To address this issue, brain activation was measured in normal male subjects while they either responded in a normal manner to erotic film excerpts or voluntarily attempted to inhibit the sexual arousal induced by viewing erotic stimuli. Results demonstrated that the sexual arousal experienced, in response to the erotic film excerpts, was associated with activation in "limbic" and paralimbic structures, such as the right amygdala, right anterior temporal pole, and hypothalamus. In addition, the attempted inhibition of the sexual arousal generated by viewing the erotic stimuli was associated with activation of the right superior frontal gyrus and right anterior cingulate gyrus. No activation was found in limbic areas. These findings reinforce the view that emotional self-regulation is normally implemented by a neural circuit comprising various prefrontal regions and subcortical limbic structures. They also suggest that humans have the capacity to influence the electrochemical dynamics of their brains, by voluntarily changing the nature of the mind processes unfolding in the psychological space.
