人脑中的额顶叶镜像神经元网络支持表现和理解观察到的行为的能力，使我们能够成功地与他人和环境互动。使用功能性磁共振成像（fMRI），我们想调查的反应，这个网络在成年人在观察层次组织的动作序列的不同复杂性，出现在不同的发展阶段。我们假设额顶叶系统可能在编码目标导向动作的层次结构中发挥作用。所有动作序列的观察招募了一个共同的双边网络，包括额顶叶镜像神经元系统和枕颞视觉运动区。镜像神经元区域的活动根据所观察到的动作的运动复杂性而变化，但不根据动作结构的发展顺序而变化，这可能是因为我们的受试者都是成年人。这些结果表明，镜像神经元系统提供了一个相当准确的模拟过程中观察到的行动，模仿内部的运动复杂性的水平。我们还讨论了镜像神经元与语言发育和进化之间的联系。(c)2006年由Elsevier Inc.出版
A fronto-parietal mirror neuron network in the human brain supports the ability to represent and understand observed actions allowing us to successfully interact with others and our environment. Using functional magnetic resonance imaging (fMRI), we wanted to investigate the response of this network in adults during observation of hierarchically organized action sequences of varying complexity that emerge at different developmental stages. We hypothesized that fronto-parietal systems may play a role in coding the hierarchical structure of object-directed actions. The observation of all action sequences recruited a common bilateral network including the fronto-parietal mirror neuron system and occipito-temporal visual motion areas. Activity in mirror neuron areas varied according to the motoric complexity of the observed actions, but not according to the developmental sequence of action structures, possibly due to the fact that our subjects were all adults. These results suggest that the mirror neuron system provides a fairly accurate simulation process of observed actions, mimicking internally the level of motoric complexity. We also discuss the results in terms of the Links between mirror neurons, language development and evolution. (c) 2006 Published by Elsevier Inc.
