我们研究的主要目标是研究人与人合作工作时的大脑功能。对于这个初步的研究，一个人机系统，调查合作工作的开发。使用功能性近红外光谱（fNIRS）检查脑中的血流变化，并确定感兴趣区域（ROI）。评估合作难度与脑活动的关系。一个人和一台机器之间的轻敲任务作为一个合作的任务。机器提供了一个声音刺激，人点击对应于这个刺激。刺激间隔是固定的，但刺激与干扰。我们假设这种干扰的程度等于合作的难度。我们的结果表明，当刺激干扰增加时，在额下回附近观察到脑激活。因此，额下回是与合作有关的大脑区域。
The primary goal of our research is to investigate brain functions during human-human cooperative work. For this preliminary study, a human-machine system to investigate cooperative work was developed. Blood flow changes in the brain were examined using functional near-infrared spectroscopy (fNIRS) and a region of interest (ROI) was determined. The relationships between the difficulty in cooperation and brain activity were assessed. A tapping task between a person and a machine was performed as a cooperative task. The machine provided a sound stimulus and the person tapped in correspondence to this stimulus. The stimulus interval was fixed, but stimuli were presented with disturbances. We assumed that degree of this disturbance was equal to the difficulty of cooperation. Our results demonstrated that cerebral activation was observed near the inferior frontal gyrus when the stimulus disturbance increased. Thus, the inferior frontal gyrus was the cerebral region associated with cooperation.
