The presence of short and sharp MEG spikes implies focal cortical dysplasia

Highlights • Epilepsy patients with FCD have needle-like MEG spikes. • The MEG spike duration in FCD was shorter than that in non-FCD lesions. • The tilt of MEG spikes in FCD was steeper than that with non-FCD lesions. • MEG spike analysis can be used to evaluate the etiology of epileptogenic lesion...
