In order to validate our analytical approach, we tested for electrodes that correlate with the generation of a motor response, and source-localized the activity to motor cortex. (a) Electrodes correlating with responses in the time window −100 to 0 ms before button press. Electrodes shown show significance at a p < 0.05 corrected threshold determined through permutation test. (b) EEG activity for motor responses source-localized as comparisons of left versus right choices without an fMRI-based prior probability map. (Online version in colour.)
