Magnetoencephalography (MEG) records spontaneous or evoked brain electrical activity and its topography. In addition, it can time electrical brain activities in response to stimuli. Its advantage is good temporal resolution, which cannot usually be done by functional magnetic resonance imaging (fMRI). At the same time, localization is only approximate. MEG studies of pseudo words reading in normal readers show early activity in lateral occipital-temporal regions bilaterally, followed after a significant delay by near simultaneous peaks of activity in the fusiform, angular, and middle temporal gyri. Subsequent activity peaks are seen in the areas of the right inferior frontal gyrus and later in the left inferior frontal gyrus.
