Points falling on the dashed blue line represent perfect prediction (slope s = 1). The literature values overestimate electric field magnitudes (measurements are 50% of predicted values, s = 0.50, green line). Skin, skull and brain conductivities are optimized to minimize prediction error for field projections (i.e. minimize mean square distance from dashed line in panel (B)) which corrects this magnitude mismatch, and is shown in Figure 5E.
