Supplementary note.

We have included as supporting information additional figures showing separately the results for the group of learners and non-learners (Figure A and B). We have also included supplementary tables with the peak values of the difference waves for the P300 effect during block 1 (Table A) and block 2 (Table B), and the results from the behavioral test with their corresponding amplitudes in the target ROI during the P300 time window (Table C).
