Fig. 2.

Sensor level spectral responses (a) and sensor positions (b). In (a) the greatest sensor level modulation (percentage change relative to rest) of beta band power with respect to the task is presented for each subject. The shading around each line indicates the standard error of the mean as assessed by bootstrapping the average across trials (100 bootstraps). Colour coded asterisks indicate when each subject deviated significantly from rest (p < .05, corrected). The boundary between the task and rest period are indicated by the grey dashed lines. In (b) the sensor positions for performing a language lateralisation experiment on an average subject are plotted relative to the MNI template. The sensors for each subject showing the greatest modulation corresponding to the traces in panel (a) are colour coded accordingly. Note that only 26 sensors were used but more sensors appear in this figure to depict the sensor for each subject that displays the maximum change in beta power.
