Abstract
Many neuromagnetic studies have established that desynchronization in the alpha to low gamma bands well reflects functional localization of motor, somatosensory, and language functions. However, it is still difficult to record neuromagnetic high-gamma activities with stability on a single trial basis. Electrocorticograms provide us with high-gamma band activities on a single trial basis. High-gamma band activities well reflects somatotopic representations, and enable accurate neural decoding. One of the technological challenges in neuromagnetism is to establish a method for neuromagnetic measurement of high-gamma band activities on a single-trial basis. This would enable not only accurate neural decoding using MEG but would also allow phase analyses revealing coupling phenomena between the gamma and other bands.
