2.4.5. Estimation of the MI Brain Response Time
EVENT
As an objective measure for estimating the rate of MI execution, we used the trials-averaged time of the sensorimotor rhythm desynchronization, which was defined for each subject as the mean moment when the first local minimum of sensorimotor rhythm energy was reached after the cue [After obtaining significant clusters, we have chosen the first one as relevant to desynchronization. We considered the first local minimum of the t-value series averaged over significant channels as the mean moment of sensorimotor rhythm desynchronization. To facilitate each event, we plotted every cluster candidate and corresponding topogram and analyzed them manually (see illustration in
