Magnetoencephalography (MEG) in focal cortical dysplasia (FCD)^*

Magnetoencephalography (MEG) and EEG reflect postsynaptic currents in pyramidal cells. MEG is selectively sensitive to tangential currents, typically produced by fissure walls. Because the bottom of sulci are predilection sites for FCD lesions, we investigated whether MEG results could predict clinical outcome in epilepsy surgery patients with FCD. We specially focused on patients with no visible lesions on magnetic resonance imaging (MRI).
