观察他人的行为会激活一个大脑区域网络，这个区域在执行这些行为的过程中也会被激活。在这里，我们使用功能性磁共振成像来测试这些位于额叶和顶叶皮层的“镜像”区域是否主要编码观察到的工具动作的空间运动方面或功能目标相关方面。参与者观看由工具对象（例如，钥匙）和目标对象（例如，钥匙孔）组成的动作的静态描述。他们判断动作的标准，要么是物体的方向是否正确，以便动作成功（空间运动任务），要么是物体是否能实现动作目标（功能任务）。与对照组相比，这两项任务都激活了左额顶叶皮层先前与动作观察和执行有关的区域。在这些区域中，运动前皮层和边缘上回在空间运动任务中主要被激活，而额叶中回在功能任务中主要被激活。在空间运动任务中，沿顶叶内沟的区域被更强烈地激活，但只有在工具物体的空间运动特性事先未知的情况下。这些结果表明，在行动观察网络中存在一种劳动分工，这种分工映射到先前提出的行动执行的类似分工。
Observing other people’s actions activates a network of brain regions that is also activated during the execution of these actions. Here, we used functional magnetic resonance imaging to test whether these “mirror” regions in frontal and parietal cortices primarily encode the spatiomotor aspects or the functional goal-related aspects of observed tool actions. Participants viewed static depictions of actions consisting of a tool object (e.g., key) and a target object (e.g., keyhole). They judged the actions either with regard to whether the objects were oriented correctly for the action to succeed (spatiomotor task) or whether an action goal could be achieved with the objects (function task). Compared with a control condition, both tasks activated regions in left frontoparietal cortex previously implicated in action observation and execution. Of these regions, the premotor cortex and supramarginal gyrus were primarily activated during the spatiomotor task, whereas the middle frontal gyrus was primarily activated during the function task. Regions along the intraparietal sulcus were more strongly activated during the spatiomotor task but only when the spatiomotor properties of the tool object were unknown in advance. These results suggest a division of labor within the action observation network that maps onto a similar division previously proposed for action execution.
