The present functional neuroimaging study focuses on the iconography of mourning. A culture-specific pattern of body postures of mourning individuals, mostly suggesting withdrawal, emerged from a survey of visual material. When used in different combinations in stylized drawings in our neuroimaging study, this material activated cortical areas commonly seen in studies of social cognition (temporo-parietal junction, superior temporal gyrus, and inferior temporal lobe), empathy for pain (somatosensory cortex), and loss (precuneus, middle/posterior cingular gyrus). This pattern of activation developed over time. While in the early phases of exposure lower association areas, such as the extrastriate body area, were active, in the late phases activation in parietal and temporal association areas and the prefrontal cortex was more prominent. These findings are consistent with the conventional and contextual character of iconographic material, and further differentiate it from emotionally negatively valenced and high-arousing stimuli. In future studies, this neuroimaging assay may be useful in characterizing interpretive appraisal of material of negative emotional valence.
当前的功能神经影像学研究聚焦于哀悼的图像学。通过对视觉材料的调查,出现了一种特定文化背景下哀悼者身体姿势的模式,大多表现为退缩。在我们的神经影像学研究中,当这种材料以不同组合用于风格化绘图时,激活了社会认知研究中常见的皮质区域(颞顶联合区、颞上回和颞下回)、对疼痛的共情(体感皮层)以及丧失感(楔前叶、中/后扣带回)。这种激活模式随时间发展。在接触的早期阶段,较低级的联合区域,如纹外体区会被激活,而在后期阶段,顶叶和颞叶联合区域以及前额叶皮层的激活更为显著。这些发现与图像材料的传统性和情境性特征相符,并进一步将其与具有负面情绪效价和高唤醒性的刺激区分开来。在未来的研究中,这种神经影像学检测方法可能有助于对具有负面情绪效价的材料进行解释性评估。
