Remote ECoG Data collection. Results of data collected from the BCI system using the Activa PC + S Nexus device. A, B ECoG data from channels 1 and 3 and filtered through a 1 Hz high-pass filter. C, F Power spectra for channels 1 and 3 (shown as \(\upmu \pm\upsigma\)). D, E Time–frequency spectrograms of averaged windows (6.4 s, N = 2051) of data that show the changes in power of frequency bands between 1–100 Hz from filtered, averaged, and normalized data during multiple transitions from the REST state (indicated by the first half of the time series) to the MOVE state
