Fig. 2.

Statistical comparison of current density images: arithmetic task minus resting state. Warm colored areas (yellow) correspond to significantly (p = .05) higher activity under the arithmetic task, and cold colored areas (cyan) correspond to significantly (p = .05) higher activity under the resting state. A: anterior. S: superior. P: posterior. I: inferior. R: right. L: left. H: hemisphere. V: view. B: bottom. The color scale corresponds to t-values corrected for multiple testing by means of non-parametric randomization of the maximum-statistics. a) Theta band. b) Alpha1 band.
