LORETA solution for spatio-temporal EEG source reconstruction

In this paper, we presented the famous method called Low resolution brain electromagnetic tomography (LORETA) used for the localization of neural electrical current. This method is used to solve the EEG (electroencephalography) inverse problems. In this study, we focused on the localization accuracy and time behavior of the LORETA method. Therefore, this method is tested using three simulated dipole configurations; single dipole, two distinct dipoles and one moving dipole. After that, the effect of the time component is highlighted on the localization accuracy and the importance of taking the maximum or average activity during our time window in the distinction peaks of activity.
