为了研究动作观察的电生理相关性，当参与者观察重复的生物(人类)或非生物运动(以1/2赫兹的频率)时，记录脑电(EEG)。采用低分辨率电磁层析(LORETA)对稳态诱发电位进行分析，并对其神经源进行研究。结果显示，在生物运动观察中，初级运动皮质和运动前皮质、辅助运动区以及顶叶后皮质的激活程度显著升高，支持皮质运动神经元的镜像特性。此外，还对区际交流进行了分析。在增量(0.5-4赫兹)和较低的阿尔法(8-10赫兹)频率下，分布式网络获得了更高的一致性，这表明在人类行动观察过程中激活的皮质区域之间存在整合和功能耦合。
To investigate electrophysiological correlates of action observation electroencephalogram (EEG) was recorded while participants observed repetitive biological (human) or non-biological movements (at 1 rate of 2 Hz). Steady-state evoked potentials were analyzed and their neural Sources were investigated using low resolution electromagnetic tomography analysis (LORETA). Results revealed significantly higher activation in the primary motor and premotor cortex, supplementary motor area as well as the posterior parietal cortices during observation of biological movements, supporting Mirror properties of cortical motor neurons. In addition, interregional communication was analyzed. Increased coherence for distributed networks at delta (0.5-4 Hz) and lower alpha (8-10 Hz) frequencies were obtained suggesting integration and functional Coupling between the activated cortical regions during human action observation.
