N2 results. (A) Time course at FCz electrode for each condition. Baseline from −200 to 0 ms at the onset of T1 was used. (B) Topographic maps of N2 for each condition. Electrodes marked with enlarged white dots were used to evaluate amplitudes of N2. (C) Mean amplitudes of N2. (D) Source localization of N2. Abbreviations: ALEX, individuals with alexithymia; NonALEX, individuals without alexithymia; **P < 0.01.
