The simultaneous recording of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) has opened several new perspectives within the field of functional MRI. It allows the detailed temporal and spectral information contained in EEG to be incorporated into the analysis of fMRI signals. In addition, it permits the study of spontaneous brain activity that can only be observed with EEG, such as epileptic spikes, sleep spindles, or alpha waves. However, the price to pay for this technical advance is the deterioration of the quality of both signals, and, in particular, of EEG. This chapter first reviews the pros and cons of sparse and continuous EEG-fMRI. It then introduces advanced recording strategies aimed at improving the quality of EEG within a continuous sampling scheme.
