Bilateral Transcranial Direct Current Stimulation Reshapes Resting-State Brain Networks: A Magnetoencephalography Assessment

Figure 3

t-maps of resting-state activity (PSD). The figure shows the topographic distribution of t-values calculated for the power spectrum density (PSD). Shades of red colors indicate positive values, shades of blue colors indicate negative values, and shades of white indicate values toward zero. The t-maps show a global reduction of PSD in all frequency bands, mostly localized in the left frontal regions.
