Abstract

Grand-average ERPs from left and right temporoparietal sites (P7/P8) showing a marked increase of N1 amplitude for group H. Mean amplitude (160–180ms) at this electrode pair showed an overall group difference (F(2,21)1⁄46.98; Po0.005) with post hoc tests (Scheffe ́) indicating differences between group H and controls (Po0.01), group H and group L (Po0.01), but no difference between group L and controls. (b) Source analysis (LORETA) for the grand average showed a prominent left temporoparietal source at 152 ms for group H subjects corresponding to Brodmann areas 19/37/39. Voxels in the region marked in black showed activity higher than 0.01mA/mm2. (c) A statistical comparison of the individual source solutions (LORETA, time window 140–180ms) of group H and control subjects revealed group differences in medial frontal and lateral temporo- occipital regions. The darker zones (encircled) represent those voxels for which t-values exceeded the threshold of significance (corrected for multiple comparisons).
