虽然许多研究已经检查了成人的动作观察网络（AON）的位置，但由于缺乏生态有效的神经成像措施，动作观察和动作执行的共享神经相关性仍然不清楚。在这项研究中，我们的目的是证明使用功能近红外光谱（fNIRS）来测量在现场任务的动作观察和动作执行区域的神经相关的可行性。30名成年人伸手去拿物体或观察实验者伸手去拿物体，同时记录他们感觉运动区和顶叶区的脑血流动力学反应，包括氧合血红蛋白（HbO）和脱氧血红蛋白（HbR）。结果表明，在动作观察和动作执行过程中，双侧顶上级小叶（SPL）、双侧顶下层小叶（IPL）、右侧缘上区（SMG）和右侧角回（AG）等顶叶区域共享神经活动。我们的研究结果证实了fNIRS在AON研究中的适用性，并为未来在发育和临床人群中的工作奠定了基础。
Although many studies have examined the location of the action observation network (AON) in human adults, the shared neural correlates of action-observation and action-execution are still unclear partially due to lack of ecologically valid neuroimaging measures. In this study, we aim to demonstrate the feasibility of using functional near infrared spectroscopy (fNIRS) to measure the neural correlates of action-observation and action execution regions during a live task. Thirty adults reached for objects or observed an experimenter reaching for objects while their cerebral hemodynamic responses including oxy-hemoglobin (HbO) and deoxy-hemoglobin (HbR) were recorded in the sensorimotor and parietal regions. Our results indicated that the parietal regions, including bilateral superior parietal lobule (SPL), bilateral inferior parietal lobule (IPL), right supra-marginal region (SMG) and right angular gyrus (AG) share neural activity during action-observation and action-execution. Our findings confirm the applicability of fNIRS for the study of the AON and lay the foundation for future work with developmental and clinical populations.
