nPE: 0.48±0.29) and beta2 (SLPE: 0.34±0.16, nPE: 0.46±0.37) maxima observed over the lateral prefrontal cortex. The statistical analysis revealed significant differences between groups exclusively in the theta band, patients with SLPE exhibiting significantly increased current density in the theta frequency band in the medial and lateral parietal cortex bilaterally, with the highest significance in the left medial parietal cortex (i.e., posterior cingulate/precuneus cortex) (SLPE: 0.30±0.32, nPE: 0.08±0.05, t max = 3.08, p = 0.006) (Fig. 2).
