The inversion of the
Electroencephalogram (EEG) to intracranial
currents enables the reconstruction of brain sources.
Brain electrical tomography, based on Evoked
Potentials (EPs), may be performed using a variety
of techniques, such as Algebraic Reconstruction
Techniques (ART), Singular Value Decomposition
(SVD) and Tikhonov Regularization Techniques
(TRT). In the present study a strategy is proposed
for selecting the most appropriate inversion
technique. The decision is based on the success of
existing criteria for computing optimum parameters
for the TRT and SVD techniques, on the condition
number of the lead-field matrix and the information
available concerning the noise, which corrupts the
EPs.
