Table 2.

Channel-based relative error (cRE) for different brain regions, calculated for AR and REST respectively. The values shown in the table are the average cRE and standard error (in brackets) across 100 dipoles at different locations of the brain, and oriented along the x-, y-, z-axis respectively. Negative values, indicating a reduction of signals after re-referencing compared to the simulated data, are shown in bold.
