Hemi, hemisphere; MA, math active (relative to baseline); MS, math selective (relative to baseline and memory); MS+, math selective, not memory active; NA, numeral active (relative to baseline); NS, numeral selective (relative to baseline, letters, and foreign symbols); TOT, total number of electrodes per region. Electrodes included are statistically significant at P < 0.05 after FDR correction (permutation test).
