在这个实验中，我们研究了镜像神经元系统和任务要求引起的注意力增加之间的关系。13名参与者被要求被动观察手指运动序列，观察这些序列的知识，他们以后必须执行的序列，最后，根据手指运动序列执行非运动数学任务。在被动观察和单独的运动执行条件下，在重叠区域发现了β波段（15-35 Hz）感觉运动去兴奋化，表明人类镜像神经元系统的活动。相对于被动观看，当参与者不得不观看刺激以稍后模仿时，以及当他们执行数学任务时，这些区域的β去极化增强，这表明镜像神经元系统的活动可以通过注意力来调节。
In this experiment we examined the relationship between the mirror neuron system and increased attention caused by task demands. Whole head MEG recordings were made from 13 participants who were asked to passively observe finger movement sequences, observe these sequences with the knowledge they would later have to perform the sequence presented, and finally, to perform a nonmotor mathematics task based on the finger-movement sequences. Beta-band (15-35 Hz) sensorimotor desynchronization was found in overlapping areas during passive observation and in a separate motor execution condition, indicating the activity of the human mirror neuron system. The beta desynchronization in these areas was enhanced relative to passive viewing when participants had to watch the stimuli to later imitate and when they performed the mathematics task, indicating that mirror neuron system activity can be modulated by attention.
