From: Analyzing EEG signals to detect unexpected obstacles during walking
Comparison of the signals obtained by two different acquisition equipments. Graphic shows the EEG signal recorded at electrode Cz during the Reaction response for the Screen mode. The red line corresponds to the BrainProducts equipment (subject S4), and blue dashed line corresponds to the g.Tec equipment (subject S3). The obstacle appears at t=0 ms
