“…The brain activity was measured using an fNIRS system (ETG‐4000; Hitachi Inc., Tokyo, Japan) because it is not affected by magnetic interference, is robust with respect to motion artefacts, 32,33 and has spatial resolution, compared to electroencephalography (EEG). In our previous studies, we compared EEG 34 and fNIRS 35 for a similar virtual surgical simulator system. Although fNIRS was inferior to EEG in terms of temporal resolution, it was sufficient to measure the brain activity during the surgical tasks because we focussed on the changes in brain activation over a relatively long time period.…”

Background: Robotic surgery improves minimally invasive interventions. However, it is challenging to determine the best gain settings for control of the endoscope.Providing the surgeon with the ability to manipulate the endoscope at an appropriate speed will likely improve the surgery by reducing the surgeon's stress. In this study, we validated the feasibility of a gain-tuning method in which the operator's brain activity is measured and used to evaluate stress levels. Methods:We developed an endoscope-manipulation simulator and used functional near-infrared spectroscopy to measure the prefrontal cortical activity, while participants controlled the simulator at different gain values. Results:The brain activation levels in the prefrontal cortex exhibited significant differences under different viewpoint motion gain conditions. Conclusions:The stress-related brain activity was significantly reduced at specific gains, indicating that the brain activity evaluation would be useful to determine the parameters related to the operator's feelings.
