A Generalized Framework for Quantifying the Dynamics of EEG Event-Related Desynchronization
Figure 3
Comparison of both methods for the estimation of state conditional ERD by means of surrugate data.
The figure contrasts the true conditional ERD (left column), the estimated conventional conditional ERD (central column) and the estimated generalized conditional ERD (right column). Each row corresponds to a particular artificial data set (I–III, top to bottom). The panels share an identical color coding scheme, where blue and red refer to ERD and ERS, respectively. The vertical and horizontal axes represent the state variable and the time, respectively.
