Foreword

Magnetoencephalography (MEG) is a powerful functional imaging technique that measures changes in the magnetic fields due to real-time neuronal function. MEG has the ability to reconstruct the neuronal sources of brain activity with spatial resolution of a few millimeters at the cortical level. The first single-channel MEG was measured in 1972, and whole-head MEG units became commercially available in the mid-1990s. There are currently about 20 clinical MEG centers in the United States. So, the $64 million (literally!) question has always been why has such a powerful imaging technique not been widely accepted?
