对另一个人执行的目标导向行为的观察可以让人们了解该人正在做什么以及他/她为什么这样做。有关他人行为的重要信息也是通过观察到的行为的动态来进行的。动作动力学描述了动作的“活力形式”，描述了执行主体和动作接受者之间的认知和情感关系。在这里，我们使用功能磁共振成像技术，评估了活力形式识别的神经相关性，向参与者展示了两个演员以不同的活力形式执行动作的视频：精力充沛的和温和的。参与者查看了两项任务中的操作。在一项任务（什么）中，他们必须专注于所呈现行动的目标；在另一个任务（如何）中，他们必须关注活力形式。对于这两个任务，在动作观察/执行电路中发现了激活。最有趣的是，对比如何与什么揭示了右背中央岛叶的激活，强调了连接体感区域与内侧颞区，特别是与海马体的解剖区域在识别活力形式方面的参与。这种体感-岛叶-边缘回路可能是观察者理解所观察到的行为所传达的活力形式的能力的基础。
The observation of goal-directed actions performed by another individual allows one to understand what that individual is doing and why he/she is doing it. Important information about others' behaviour is also carried out by the dynamics of the observed action. Action dynamics characterize the 'vitality form' of an action describing the cognitive and affective relation between the performing agent and the action recipient. Here, using the fMRI technique, we assessed the neural correlates of vitality form recognition presenting participants with videos showing two actors executing actions with different vitality forms: energetic and gentle. The participants viewed the actions in two tasks. In one task (what), they had to focus on the goal of the presented action; in the other task (how), they had to focus on the vitality form. For both tasks, activations were found in the action observation/execution circuit. Most interestingly, the contrast how vs what revealed activation in right dorso-central insula, highlighting the involvement, in the recognition of vitality form, of an anatomical region connecting somatosensory areas with the medial temporal region and, in particular, with the hippocampus. This somatosensory-insular-limbic circuit could underlie the observers' capacity to understand the vitality forms conveyed by the observed action.
