This voxel-based morphometry study investigated whether the personality trait disgust proneness is associated with gray matter volume (GMV) of distinct brain regions implicated in disgust processing. We analyzed brain structural data from 99 healthy women, who had rated their tendency to experience disgust for different disgust domains (offensive food, death, poor hygiene, decay, and body secretions). Food-related disgust proneness was positively correlated with insula volume. The disgust domains decay and death showed negative correlations with GMV of the dorsomedial and the dorsolateral prefrontal cortex (DMPFC, DLPFC). Our data implicate that only core disgust shows an association with the GMV of the gustatory cortex, whereas the reactivity to other disgust areas is linked with cognitive control areas.
这项基于体素的形态测量学研究旨在探讨人格特质易恶心是否与不同与厌恶处理相关的脑区的灰质体积（GMV）有关。我们分析了 99 名健康女性的脑结构数据，这些女性对不同厌恶领域（令人不快的食物、死亡、卫生条件差、腐烂和身体分泌物）的恶心倾向进行了评分。与食物相关的恶心易感性与脑岛体积呈正相关。厌恶领域的腐烂和死亡与背内侧和背外侧前额叶皮质（DMPFC、DLPFC）的 GMV 呈负相关。我们的数据表明，只有核心厌恶与味觉皮层的 GMV 存在关联，而对其他厌恶区域的反应则与认知控制区域有关。
