The human gustatory system has been studied using a lot of imaging modalities. EEG and MEG have the advantage of millisecond time resolution but have limited spatial resolution and localization than fMRI. EEG also provides information regarding regional neuronal activity, although has a much minor spatial resolution compared to MEG. In MEG the magnetic field which is hardly affected by intervening tissues such as the skull, in contrast to the electrical field. fMRI, PET and MEG have the advantage of being able to image deeper brain regions.
