当我们看着自己的倒影，或者移动电子游戏中的角色时，我们看到自己的动作是由一个与我们身体分离的代理完成的。然而，我们认为代理人就是我们自己。利用功能磁共振成像，我们试图探索分离的神经基础，即自我属性从自己身体的边界投射到外部实体的认知机制。17名参与者观看了一场视频游戏，游戏中3名玩家互相扔球。受试者的按键可以与玩家的动作同步或异步（任务：代理vs.控制）。游戏从四种视角中的一种进行展示，这些视角可以固定或改变每次试验（视图：固定vs可变）。与先前的研究一致，当代理人的运动与参与者的运动同步时，左脑岛被激活（TASK的主要效应，第6页）
When looking to our reflection, or moving a video-game character, we see our own movement preformed by an agent which is physically separated from our body. Yet, we consider the agent to be ourself. Using fMRI, we sought to explore the neural underpinnings of disembodiment, the cognitive mechanism under which the properties of the self are projected away from the boundaries of one's own body towards an external entity. Seventeen participants watched a video-game in which three players threw each other a ball. Subjects' key-press could either be synchronous or asynchronous with one of the players' action (TASK: Agency vs. Control). The game was shown from one of four viewpoints which could either be fixed or change every trial (VIEWS: Fixed vs. Changeable). Consistent with previous studies, the left insula was activated when the agent's movements were synchronous with those of the participants (main effect of TASK, p
