Some kinds of brain imaging data seem to be quite well described by the ICA model. This is especially the case with electroencephalograms (EEG) and magnetoencephalograms (MEG), which are recordings of electric and magnetic fields of signals emerging from neural currents within the brain. In this chapter, the authors review some of these brain imaging applications, concentrating on EEG and MEG.
