Illustration of How New Study Demonstrates that a Brain-Computer Interface Can Improve Performance

Caption

Study participants navigated a virtual plane up and down through a course of red boxes while we recorded their electrical brain activity from an electroencephalography (EEG) cap (see top panel). The participants became more and more agitated as the course also became more and more difficult over time which lead most participants to miss one of the boxes (i.e. crashed the plane) in the middle of the course (see Control, bottom panel). When we provided a brain-computer interface (BCI) based neurofeedback signal that reflected their level of stress or arousal, participants were able to decrease their arousal level, which in term improved their task performance.
