  • Look Inside

Non-invasive studies of pain perception in the human brain have been performed by positron emission tomography (PET), functional magnetic resonance imaging (fMRI) , electroencephalography (EEG) and magnetoencephalography (MEG). PET and fMRI, which reflect metabolic changes by painful stimulation, have excellent spatial resolution in the order of mm, but their temporal resolution is not so high. In contrast, EEG and MEG, which reflect physiological changes, have excellent temporal resolution in the order of msec. However, it is difficult for EEG and MEG to detect activities in the deep areas such as the thalamus.
