我们在功能性磁共振成像研究中调查了主观和血流动力学对恶心诱导、恐惧诱导和中性图片的反应。在1周的时间间隔内，24名男性受试者进行了两次相同的分组设计，以分析重复图片呈现可能产生的反应变化。结果表明，与中性场景相比，引起厌恶和恐惧的场景引发了相似的激活模式。这包括丘脑、初级和次级视野、杏仁核、海马体和前额皮质的各个区域。在重新测试期间，情感评分几乎没有变化。相比之下，除了颞枕部的激活外，大多数先前观察到的大脑激活都消失了。另一项分析比较了两种演示过程中与情绪相关的激活模式，结果表明，对引起恐惧的图片的反应比引起厌恶的图片的反应更稳定。
We investigated subjective and hemodynamic responses towards disgust-inducing, fear-inducing, and neutral pictures in a functional magnetic resonance imaging study. Within an interval of 1 week, 24 male subjects underwent the same block design twice in order to analyze possible response changes to the repeated picture presentation. The results showed that disgust-inducing and fear-inducing scenes provoked a similar activation pattern in comparison to neutral scenes. This included the thalamus, primary and secondary visual fields, the amygdala, the hippocampus, and various regions of the prefrontal cortex. During the retest, the affective ratings hardly changed. In contrast, most of the previously observed brain activations disappeared, with the exception of the temporo-occipital activation. An additional analysis, which compared the emotion-related activation patterns during the two presentations, showed that the responses to the fear-inducing pictures were more stable than the responses to the disgust-inducing ones.
