Efforts to localize neural activity associated with self-and other-referential processing have described the activity in the medial prefrontal cortex(mPFC), the anterior cingulate cortex(ACC), and the anterior insula for self-versus other-referencing and activity in the precuneus for other-versus self-referencing. We therefore explored differences in brain activity between patients with schizophrenia and normal controls using functional magnetic resonance imaging(fMRI). Normal controls showed higher activation of the anterior insula, which is associated with self-reflection, whereas patients with schizophrenia showed higher activation of the precuneus, an area associated with other-reflection, even though they were contemplating the correctness of their own answers. These results indicate that patients with schizophrenia may perceive themselves not as self but as other, even during tasks requiring them to reflect on themselves.

与自我和其他指定处理相关的神经活动的努力描述了内侧前额叶皮层（MPFC）的活性，前扣带回皮层（ACC）和对其他自我引起的前后自我引起的自我反versus的前岛和前岛。因此，我们使用功能磁共振成像（fMRI）探讨了精神分裂症患者和正常对照患者之间大脑活动的差异。正常对照显示出更高的前岛激活，这与自我反射有关，而精神分裂症患者的前反射患者的激活较高，即precuneus，即与其他反射相关的区域，即使他们正在考虑自己答案的正确性。这些结果表明，精神分裂症患者可能会认为自己不是自我，而是其他人，即使在要求他们反思自己的任务期间。
