A Combination of Pre- and Postprocessing Techniques to Enhance Self-Paced BCIs
Figure 3
Time-frequency ERD/ERS maps of all subjects, calculated for all 3 runs together. Only significant () band power changes in 0–7.5 s and in a frequency range 6–35 Hz are displayed. For each subject, constant-bandwidth filters (b) and constant- filters are plotted (a). The significant power decrease (ERD) and power increase (ERS) are displayed in red and blue colors, respectively.
