Figure 3. Effects of tDCS on the second harmonic ERS response.

Figure 3

A) Group mean beamformer images (pseudo-t; see left color bar) of the 30 Hz ERS response are shown for the active (left image) and sham (middle image) groups individually, while the statistical map (active vs. sham) is shown on the right (corrected p-values; see right color bar). The active group had significantly reduced ERS responses compared to the sham group in the medial occipital cortices (p < .01, corrected; right image). Axial slices are shown in radiologic convention (right = left). B) Virtual sensor time series data is shown for the peak voxel of the statistical map, with the sham group data appearing in blue and the active group shown with a red line. Shaded areas denote SEM.
