活力形式是一个术语，描述了动作执行的风格(例如，粗鲁、温和等)。它们代表了有意识和无意识的身体交流的一个特征要素。尽管活力形式在人际行为中很重要，但到目前为止，它们在神经科学中几乎被忽视了。在这里，我们使用功能磁共振成像(FMRI)技术，研究了三种不同任务：动作观察、想象和执行时活力形式的神经关联。联合分析表明，在所有三个任务中，都有共同、一致的脑岛背中心区激活。此外，还发现了顶额叶网络的一种常见激活，该网络通常在手臂动作的产生、规划和观察中活跃。我们的结论是，岛叶的背中央部分是调节皮质运动活动的系统的关键元素，允许个体通过动作活力形式表达其内部状态。最近的猴子解剖数据表明，岛的背中心部确实与参与控制手臂运动的皮质回路相连。
Vitality form is a term that describes the style with which motor actions are performed (e.g., rude, gentle, etc.). They represent one characterizing element of conscious and unconscious bodily communication. Despite their importance in interpersonal behavior, vitality forms have been, until now, virtually neglected in neuroscience. Here, using the functional MRI (fMRI) technique, we investigated the neural correlates of vitality forms in three different tasks: action observation, imagination, and execution. Conjunction analysis showed that, in all three tasks, there is a common, consistent activation of the dorsocentral sector of the insula. In addition, a common activation of the parietofrontal network, typically active during arm movements production, planning, and observation, was also found. We conclude that the dorsocentral part of the insula is a key element of the system that modulates the cortical motor activity, allowing individuals to express their internal states through action vitality forms. Recent monkey anatomical data show that the dorsocentral sector of the insula is, indeed, connected with the cortical circuit involved in the control of arm movements.
