The aim of this research was to reveal how the brain process sensory feedback during self-generated hand action, which is functionally correlated with sense of agency. We examined activity of single neurons from the inferior parietal lobule; AIP/PFG of macaque monkeys during execution of grasping action viewing video monitor that presented their online movements, and during fixating video clips of their own grasping action. We found that some of hand manipulation-related neurons in AIP/PFG responded to video clips of one's own and experimenter's hand movement. Some of these neurons (including mirror neurons) also responded to the video clips of one's own hand movement without the image of the target object. These results suggest that these neurons visually responded to one's own hand kinematics, representing the body scheme rather than the goal of action. We still have been involved in the experiment in which sensory feedback are applied perturbation during hand movement.

这项研究的目的是揭示大脑在自我生成的手部动作期间如何处理感觉反馈，这在功能上与代理感相关。我们检查了顶下小叶单个神经元的活动；猕猴在执行抓握动作期间观看呈现其在线动作的视频监视器，以及在固定自己抓握动作的视频剪辑期间的 AIP/PFG。我们发现 AIP/PFG 中一些与手部操作相关的神经元对自己和实验者手部动作的视频片段做出反应。其中一些神经元（包括镜像神经元）还对自己手部运动的视频片段做出反应，而没有目标物体的图像。这些结果表明，这些神经元对自己的手部运动学做出视觉反应，代表身体方案而不是行动目标。我们仍然参与了在手部运动过程中应用感觉反馈扰动的实验。
