Stroke beta band tb-Coh in the deficit electrode (C3) during the tracking period.

The hemisphere contralateral to the tested arm (paretic/non-dominant) is displayed on the left. The tb-Coh (coherence change from baseline period) averaged across participants is shown for the deficit electrode (C3). The control reference inset shows electrode C3’s tb-Coh averaged across participants and sessions (control-Vibe and control-Sham) for the Pre-TV block. Values of tb-Coh were interpolated between electrodes for mapping. Positive/negative values indicate an increase/decrease in tb-Coh relative to the baseline period. The black dots indicate the location of the deficit electrode (C3).
