From: Analyzing EEG signals to detect unexpected obstacles during walking
Average potential of all subjects (three for the Laser mode and five for the Screen mode) of the EEG signals recorded at electrodes FCz, Cz, C1 and C2. Top: Laser mode. Bottom: Screen mode. The obstacle appears at t=0 ms. The straight red line represents the Reaction response while the dashed blue line corresponds to the No reaction response
