From Signals to Dynamic Cortical Networks

Magnetoencephalography (MEG), an invaluable functional brain imaging technique, provides direct, real-time monitoring of neuronal activity which is necessary for gaining insight into dynamic cortical networks. One distinct advantage of measuring weak extracranial neuromagnetic fields is that there is little attenuation in amplitude and/or smearing of the signals since they are primarily generated by primary current sources and are minimally perturbed by the intervening tissues of brain, skull, and scalp. MEG permits spatiotemporal tracking of cortical pathways with sub-millisecond temporal resolution.
