Agency is the sense that I am the one generating an action. In this neuroimaging experiment, subjects controlled a circle with a mouse while requested either to lead another circle (i.e., being the agent) or to follow it (i.e., being acted upon). Clusters within the right intraparietal sulcus were associated with following for the most rostral and leading for the most caudal ones. Bilateral activity in the inferior parietal lobule in conditions involving confusion about the origin of the action confirmed its role in agency. A lateralization effect was also found in these conditions, the response being stronger in the left inferior parietal lobule when subjects were not the agent of the performed action, and in the right when they were.
能动性是指我是产生行动的主体这一感觉。在这个神经成像实验中，受试者用鼠标控制一个圆圈，同时被要求要么引导另一个圆圈（即作为主体），要么跟随它（即被作用）。右侧顶内沟内的集群与最靠前的跟随动作以及最靠后的引导动作相关。在涉及对行动起源感到困惑的情况下，双侧顶下小叶的活动证实了其在能动性中的作用。在这些情况下还发现了一种偏侧化效应，当受试者不是所执行动作的主体时，左侧顶下小叶的反应更强，而当他们是主体时，右侧的反应更强。
