A simple method for calculating the depth of EEG sources using minimum norm estimates (MNE)

Abstract: Neural source localization using electroencephalographic data is usually performed using either dipolar models or minimum norm based techniques. While the former demands a priori information about the number of active sources and is particularly suitable for generators, which occupy small pieces of cortical tissue, the major drawbacks of the second approach are its dependence on the uncorrelated noise, and its tendency to localize the sources at the surface. In this paper, a simple mathematical procedure, base… Show more

“…The head model was computed through the use of OpenMEEG (Gramfort, Papadopoulo, Olivi, & Clerc 2010) based on the EEG cap that was used. The source of the brain electrical signal was reconstructed by applying the Minimum Norm Method (wMNE; output mode: Kernel; Pinto & Silva 2007). The source orientation was unconstrained, meaning that each vertex of the cortex surface contained three dipoles with orthogonal directions.…”

“…9 Various methods have been proposed for choosing suitable constraints for the inverse EEG problem, the most wellknown being the minimum norm (MN) constraint. [10][11][12] Techniques relying on the MN constraint are based on a search for the solution with minimum power, along with regularization. 8 In other words, when the system is underdetermined, the solution is obtained by minimizing the l 2 -norm of the solution components.…”

“…Minimum norm methods have e. g. been used to reconstruct pipeline defects in nondestructive testing [13]. They have also been widely applied in the reconstruction of current sources from EEG and MEG measurements of the human brain and MCG measurements of the human heart [11,18,20].…”
