Abstract :
New methods of adding temporal constraints to the inverse EEG problem for spatially constrained distributed sources are presented and compared to standard minimum norm solutions. It is shown that under assumption of uncorrelated noise the new methods allow for a more accurate determination of location and timing of large scale cortical electrical activity
