  The Electro-Encephalo-Graphy (EEG) technique consists of estimating the
cortical distribution of signals over time of electrical activity and also of
locating the zones of primary sensory projection. Moreover, it is able to
record respectively the variations of potential and field magnetic waves
generated by electrical activity in the brain every millisecond. Concerning,
the study of the localization source, the brain localizationactivity requires
the solution of a inverse problem. Many different imaging methods are used to
solve the inverse problem.The aim of the presentstudy is to provide comparison
criteria for choosing the least bad method. Hence, the transcranial magnetic
stimulation (TMS) and electroencephalography (EEG) technique are combined for
the sake of studying the dynamics of the brain at rest following a disturbance.
The study focuses in the comparison of the following methods for EEG following
stimulation by TMS: sLORETA (standardized Low Resolution Electromagnetic
Tomography), MNE (Minimum Estimate of the standard), dSPM (dynamic Statistical
Parametric Mapping) and wMEM (wavelet based on the Maximum Entropy on the
Mean)in order to study the impact of TMS towards rest and to study inter and
intra zone connectivity.The contribution of the comparison is demonstrated via
the stages of the simulations.
