Strategies for brain sources and tissues properties identification from EEG/MEG and EIT signals

The estimation of human brain cellular activity from EEG/MEG signals requires a rather accurate knowledge of the living tissues electrical properties. The identification of these properties from joint EEG/MEG measurements as well as from impedance tomography has been thoroughly investigated in literature. In this paper, an assessment of the information content coming from each diagnostics, and their possible interactions, will be presented and discussed.
