Thought-action fusion (TAF) is a tendency of individuals to establish causal relations between their own thoughts and external reality. TAF can lead to maladaptive behaviors typically observed in obsessional thoughts. However, neural mechanisms underlying TAF are still unknown. In this study, 38 healthy men were informed that MR signals were able to detect thoughts of the word 'apple' and that this recognition could result in the administration of electrical shocks to a person outside the scanner. During MR acquisition, they were asked to suppress or not suppress the thought of 'apple' while sham electrical shocks were or were not administered to the other person. The main effect of the sham administration of electrical shock to another person was shown in the bilateral lingual gyri, fusiform gyri, and middle occipital cortices (FDR corrected p < 0.05). Also, fusiform gyrus, lingual gyrus, and middle occipital cortex activity correlated with scores of guilty feeling only when participants consciously tried to think of apple as less as possible. Our study demonstrates that visual association areas may play primary roles in TAF. The simple belief and visual imagery that one's thought may lead to someone's injury activated visual areas of the brain where, in turn, brain activity is associated with feelings of guilt.

相信正在看到:健康男性成年人中的思想-动作融合的功能磁共振成像研究。

思想行动融合(TAF)是个人在自己的思想与外部现实之间建立因果关系的趋势。TAF可以导致通常在痴迷的思想中观察到的不良适应行为。然而,TAF背后的神经机制仍然未知。在这项研究中,有38位健康的男性被告知MR信号能够检测到“苹果”一词的想法,并且这种认识可能导致对扫描仪外部人员进行电击。在MR采集过程中,要求他们抑制或不抑制对“假人”的想法,而对其他人进行或不进行假电击。双侧舌状回,梭状回,假性给予他人电击的主要效果 和枕骨中部皮质(FDR校正后p <0.05)。而且,只有当参与者有意识地尝试尽可能少地思考苹果时,梭状回,舌状回和枕中皮质活动才与内feeling感相关。我们的研究表明,视觉联想区域可能在TAF中起主要作用。一个人的思想可能导致某人受伤的简单信念和视觉意象激活了大脑的视觉区域,在此大脑活动又与内is感相关。
