Mirror neuron was found as a part of neural mechanism discriminating behavioral intension regardless of who perform the action. However, there were few studies tested the mirror neuron systematically. We applied a novel recording technique, multi-dimensional recording technique in monkeys when they performed food reaching task and reaching observation task. We recorded neural activity from entire lateral cortex and analyzed the activity. There were regions showed mirror neuron properties in prefrontal, parietal, premotor and supplementary motor area that were consistent with previous reports.

镜像神经元被发现是区分行为意图的神经机制的一部分，无论谁执行该动作。然而，很少有研究系统地测试镜像神经元。我们在猴子执行食物到达任务和到达观察任务时应用了一种新颖的记录技术，即多维记录技术。我们记录了整个外侧皮层的神经活动并分析了该活动。前额叶、顶叶、运动前和辅助运动区的一些区域显示出镜像神经元特性，这与之前的报道一致。
