Feasibility of a Hybrid Brain-Computer Interface for Advanced Functional Electrical Therapy
Figure 4
Normalized band-powers BP1, BP2, BP3, and BPmu from (a) to (d). Nine successful trials (TP), three per each LED, for subject S2 during the representative 100-second interval are shown. Turquoise vertical dotted lines in (a), (b), and (c) point to the time instants of visual focuses on LED1, LED2, and LED3, respectively, while red vertical dotted lines refer to the correct detections of SSVEP1, SSVEP2, and SSVEP3, respectively. Red lines in (d) mark all the correct SSVEP detections (TPssvep), that is, cues for MI. Blue horizontal dotted lines in (a), (b), (c), and (d) present the corresponding thresholds TH1, TH2,TH3, and THerd, respectively. Green vertcial dotted lines mark the correct ERD detections (TPerd).
