Neuroimaging investigations of self-processing have generally focused on the neural correlates of explicit self-reflection. However, very little is known about the neural basis of implicit self-related processes. We utilized the concept of self-schemas to construct a two-task fMRI study that elicited both implicit and explicit self-relevant processes. The sample consisted of 18 participants who were schematic for either athletics or science. In the implicit self-relevance task, individuals made non-self-relevant judgments about affectively neutral scientific and athletic images. In the explicit self-reference task, participants judged the self-descriptiveness of adjectives related to athletics or science. Implicit and explicit processing of self-relevant (schematic) material elicited activity in many of the same regions, including medial prefrontal cortex, posterior cingulate/precuneus, ventromedial prefrontal cortex, subgenual anterior cingulate, amygdala, and ventral striatum. We suggest that processing self-related material recruits similar neural networks regardless of whether the self-relevance is made explicit or not.
神经影像学对自我加工的研究主要集中在明确自我反省的神经相关性上。然而，关于内隐自我相关过程的神经基础知之甚少。我们利用自我图式的概念构建了一项 fMRI 双任务研究，引发了内隐和外显的自我相关过程。该样本由 18 名对运动或科学有图式的参与者组成。在内隐自我相关性任务中，个体对情绪中性的科学和运动图像进行非自我相关性判断。在外显自我参照任务中，参与者判断与运动或科学相关的形容词的自我描述性。自我相关（图式）材料的内隐和外显处理在许多相同的区域引起了活动，包括内侧前额叶皮层、后扣带回/楔前叶、腹内侧前额叶皮层、前扣带回腹侧亚区、杏仁核和腹侧纹状体。我们认为，无论自我相关性是否明确，处理自我相关材料都会招募相似的神经网络。
