FIG. 1.

(Color) Top left-hand panel: 50 single trial LFP time traces from a parietal channel. Lower left-hand panel: the average of 888 trials from the same channel and same experimental condition. Top right-hand: raster plot of 222 single-trial LFP time traces sorted according to the reaction time (RT) from a different parietal channel. Lower right-hand: average of the signals from the same channel. Time 0 denotes stimulus onset. Here AERP stands for average event-related potential.

Top: two estimated component waveforms; middle: amplitude distributions of the two components; and bottom: latency distribution of the two components. Taken from Ref. 6 .

FIG. 3.

Average evoked response for the parietal channel in Fig. 1 (top right-hand panel). Latency vs RT for the two components. Taken from Ref. 6 .

(A) Mean power spectra averaged over all recording sites, (B) mean coherence, and (C) mean Granger causality spectra averaged over all significant site pairs. Taken from Ref. 16 .

Granger causality graphs for the beta oscillatory network in sensorimotor cortex of (a) the right-hand hemisphere of GE and (b) the left-hand hemisphere of LU. Adapted from Ref. 22 .
