We studied the neural mechanisms that are engaged during the experience of beauty derived from sorrow and from joy, two experiences that share a common denominator (beauty) but are linked to opposite emotional valences. Twenty subjects viewed and rerated, in a functional magnetic resonance imaging scanner, 120 images which each had classified into the following four categories: beautiful and sad; beautiful and joyful; neutral; ugly. The medial orbito-frontal cortex (mOFC) was active during the experience of both types of beauty. Otherwise, the two experiences engaged different parts of the brain: joyful beauty engaged areas linked to positive emotions while sorrowful beauty engaged areas linked to negative experiences. Separate regions of the cerebellum were engaged during experience of the two conditions. A functional connectivity analysis indicated that the activity within the mOFC was modulated by the supplementary motor area/middle cingulate cortex, known to be engaged during empathetic experiences provoked by other peoples' sadness.

我们研究了在源自悲伤和喜悦的美感体验过程中所涉及的神经机制,这两种体验有着一个共同特征(美),但却与相反的情感效价相关联。20名受试者在功能磁共振成像扫描仪中观看并重新评定了120张图像,这些图像被分类为以下四类:美丽且悲伤;美丽且愉悦;中性;丑陋。在两种美感体验过程中,内侧眶额皮质(mOFC)均处于活跃状态。否则,这两种体验涉及大脑的不同区域:愉悦之美涉及与积极情绪相关的区域,而悲伤之美涉及与消极体验相关的区域。在这两种情况下的体验过程中,小脑的不同区域被激活。功能连接分析表明,mOFC内的活动受到辅助运动区/中央前回中部皮质的调节,已知该区域在他人悲伤引发的共情体验中会被激活。《人类大脑图谱》38:4185 - 4200,2017年。© 2017威利期刊公司。
