Despite the long history of rheoencephalography (REG), someimportant aspects of the method are still debatable. Bioimpedancemeasurements offer great potential benefit for study of the humanbrain, but the traditional four or six electrode method suffers frompotential misinterpretations and lack of accuracy. The objective ofthis paper is to study the possible mechanism of REG formation bymeans of numerical modelling using a realistic finite element modelof the human head. It is shown that the cardiac related variationsin electrical resistivity of the scalp contributes more than 60% tothe REG amplitude, whereas the brain and cerebrospinal fluid aremutually compensated by each over.
