目的在检查大脑活动时，通过适当的任务设计来减少受试者的疲劳，同时保持数据质量是很重要的。本研究评估了设计用于减少疲劳的设备如何影响功能性近红外光谱（fNIRS）数据。方法采用WOT-100型10通道可穿戴近红外光谱仪对13名健康志愿者的前额叶区域进行研究。刺激任务是一致的不一致Stroop测试，但有两个变化。首先，受试者的答案可以通过发声或键盘输出来传递。其次是在控制期间是否存在诸如简单的手指运动或发声之类的抵消。使用这两种变体进行了四次会话。fNIRS数据在刺激期间的相对变化作为大脑活动的标志。结果使用语音输出时，只有两个通道（通道3:p = 0.040，通道9:p = 0.022）存在显著差异。结论该结果可能是由于声音输出来自颞叶区，靠近前额叶区。我们发现，遗漏键盘输出的偏移可能是可能的，因为只有一个小的影响，但语音输出的偏移是必要的。
PurposeWhen examining cerebral activity, it is important to decrease a subject’s fatigue with an appropriate task design that also maintains data quality. This study evaluated how well devices designed to reduce fatigue would affect functional near-infrared spectroscopy (fNIRS) data.MethodA WOT-100 10-channel wearable fNIRS system was used to study the prefrontal areas of thirteen healthy volunteers. The stimulation task was a consistent incongruent Stroop test, but with two variations. First, the subjects’ answers could be delivered either by vocalization or keyboard output. Second was whether or not there was an offset such as simple finger movements or vocalization during control periods. Four sessions using both variations were performed. The relative changes of fNIRS data during the stimulation periods were used as a marker for cerebral activity.ResultsThere was only a significant difference in two channels (Channel 3: p = 0.040, Channel 9: p = 0.022) when voice output was used.ConclusionThe result might have been due to voice output being generated from the temporal area, near the prefrontal area. We found that the omission of offset with keyboard output might be possible as there was only a small effect, but offset with voice output is necessary.
