Name Comment

MNE2 + simple
− currents packed towards surface of volume
MNE (weighted)2 /current-gain+ no surface bias
− blurry images
LORETA2Laplacian++ deep source accurate
− estimates superficial sources too deep
MCE1 /current-gain+ focal estimates
− strong sensitivity to noise

MNE: minimum norm estimate (e.g., [42]). MCE: minimum current estimate [46]. LORETA: low resolution brain electromagnetic tomography [45]. Mathematical operator representing flux density and gradient flow of a function.
