Fig. 6: Overlap analysis of current source distribution underlying the Nt and Pd.

a Time-cumulative source distributions (180–300 ms) of the Nt (red) and Pd (turquoise). b Results of a statistical non-parametric mapping (SnPM) analysis comparing the Nt and Pd. Significant time ranges of topographical differences are highlighted in gray. The 3D-maps show the distribution of significant topographical differences at selected time points.
