Midline ERPs to tone changes (light blue) and pattern changes (dark blue) runs. P3a is typically maximal over central electrodes (FCZ and CZ), and peaks approximately 200–300 ms post stimulus. The P3b is typically maximal over parietal electrodes (CPZ and PZ), and peaks approximately 300 ms post stimulus;80 ERP data from ref. 81.
