Neuromagnetic Imaging of Synchronized MU Activity

Sensory stimulation at certain frequencies was shown to elicit EEG and MEG (MagnetoEncephaloGraphic) responses persisting longer than one second after the stimulation. Such responses have been described as a consequence of a process of synchronization of bioelectrical spontaneous activities in the brain with a specific frequency content, but otherwise uncorrelated (Narici et a1 1987a).
