An essential characteristic of human behavior is the ability to act out of intrinsic motivation to achieve desired goals. These kinds of actions have been classed as intentional or voluntary. They contrast with actions that are performed in response to external stimuli. Recent research has begun to explore the functional underpinnings of internally guided actions and how they differ from externally guided actions. From these studies, one can conclude that the two action modes differ with respect to their neural and behavioral correlates. Most importantly, functional neuroimaging and also lesion studies point to a crucial role of the frontomedian cortex in intentional actions. The present paper reviews the neuroanatomical, behavioral, electroencephalographical and functional neuroimaging findings related to intentional actions.The reviewed data suggest two dimensions for the control of action: First, a medial-lateral dimension with regard to intentional vs. stimulus-based action control. Second, an anterior-posterior dimension related to more abstract vs. specific decisions of action parameters.
人类行为的一个重要特征是能够出于内在动机采取行动以实现期望的目标。这些行为被归类为有意或自愿的。它们与响应外部刺激而执行的行为形成对比。最近的研究开始探索内在引导行为的功能基础以及它们与外在引导行为的区别。从这些研究中，可以得出结论，两种行为模式在神经和行为方面存在差异。最重要的是，功能神经影像学和损伤研究都指出前额中线皮层在有意行为中起着关键作用。本文综述了与有意行为相关的神经解剖学、行为学、脑电图和功能神经影像学研究结果。综述的数据表明，行动控制有两个维度：第一，与基于意图的行动控制有关的内侧-外侧维度。第二，与行动参数的更抽象与具体决策有关的前-后维度。
