Figures & data

Figure 1 Voxel-wise statistical non-parametric map (SnPM) of resting state sLORETA images in all patients (n=19) compared to healthy controls (n=15) at the 0.05 significance level after the correction for multiple comparisons. Yellow/red shades indicate increased delta sources (red for P<0.1; yellow for P<0.05). Structural anatomy is shown in gray scale (A – anterior; P – posterior; L – left; R – right).

Yellow/red shades indicate increased delta sources (red for P<0.1; yellow for P<0.05). Structural anatomy is shown in gray scale (A – anterior; P – posterior; L – left; R – right).
