Cognitive reappraisal recruits prefrontal and parietal cortical areas. Because of the near exclusive usage in past research of visual stimuli to elicit emotions, it is unknown whether the same neural substrates underlie the reappraisal of emotions induced through other sensory modalities. Here, participants reappraised their emotions in order to increase or decrease their emotional response to angry prosody, or maintained their attention to it in a control condition. Neural activity was monitored with fMRI, and connectivity was investigated by using psychophysiological interaction analyses. A right-sided network encompassing the superior temporal gyrus, the superior temporal sulcus and the inferior frontal gyrus was found to underlie the processing of angry prosody. During reappraisal to increase emotional response, the left superior frontal gyrus showed increased activity and became functionally coupled to right auditory cortices. During reappraisal to decrease emotional response, a network that included the medial frontal gyrus and posterior parietal areas showed increased activation and greater functional connectivity with bilateral auditory regions. Activations pertaining to this network were more extended on the right side of the brain. Although directionality cannot be inferred from PPI analyses, the findings suggest a similar frontoparietal network for the reappraisal of visually and auditorily induced negative emotions.
认知重评会激活前额叶和顶叶皮质区域。由于以往研究几乎仅使用视觉刺激来引发情绪,因此尚不清楚通过其他感觉模态诱发的情绪重评是否基于相同的神经基质。在此,参与者对自己的情绪进行重评,以增强或减弱他们对愤怒韵律的情绪反应,或者在对照条件下保持对其的关注。通过功能磁共振成像监测神经活动,并使用心理生理交互分析来研究连通性。发现一个包括颞上回、颞上沟和额下回的右侧网络是处理愤怒韵律的基础。在重评以增强情绪反应期间,左侧额上回显示出活动增加,并与右侧听觉皮层建立了功能耦合。在重评以减弱情绪反应期间,一个包括额内侧回和顶叶后部区域的网络显示出激活增加,并与双侧听觉区域具有更强的功能连通性。与该网络相关的激活在大脑右侧更为广泛。尽管无法从心理生理交互分析中推断出方向性,但研究结果表明,对于视觉和听觉诱发的负面情绪重评,存在一个类似的额顶叶网络。
