ERD/ERS and TFDF values. Maps of ERD/ERS and TFDF values for a subject. (A) ERD/ERS maps of one example: time-frequency selection was performed within the large rectangle (solid line). The small rectangle (dashed line) shows the time-frequency region with the largest TFDF value. (B) TFDF values of the time-frequency regions with 4-Hz wide frequency bands and 2-s wide time segments. The largest value is marked out by a small rectangle.
