Current source density (CSD) maps around the P100 and N100 peak latencies during real-face and face-like perceptions. In the CSD maps of N100, the TLE patients had noticeable activity at the right anterior area in the pareidolia condition, but there was no difference in face condition between controls and TLE patients. In the CSD maps of P100, the TLE patients showed more diffuse source activity during the pareidolia condition. The TLE patients also showed stronger activation at the right posterior area in the pareidolia condition compared to the face condition for the N100 wave
