Impact of spline rigidity on CSD amplitude estimates (lambda = 10-5) of Model 1 shallow and deep focal generators in comparison to NR. A more flexible spline (m = 3) leads to a more precise localization of generators, but at the expense of further attenuation with depth. Conversely, a stiffer spline (m = 5) results in less attenuation than the untransformed NR EEG, but oversmooths shallow generators.
