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

Figure 2

Resting-state activity (PSD) cortical t-value distribution. Histograms with red bars and the superimposed density plot with the thin line were calculated from the observed t-value distribution for the frequency bands under investigation. The tick black line shows a theoretical null-hypothesis distribution, with zero mean and zero median and the same variability of the empirical distribution. x-axes: t-value; y-axes: frequency of cortical vertices exhibiting a specific t-value expressed as proportion on the entire sample (intensity).
