title: Intracranial video-EEG and surgery for focal atonic seizures.
abstract: Atonic seizures are epileptic attacks characterised by a sudden loss or diminution of muscle tone. Structures corresponding to inhibitory cortical areas, such as the primary negative motor area or the supplementary negative motor area, could be responsible. We present findings observed in a patient with atonic seizures due to focal epilepsy, who underwent intracranial video-EEG monitoring and epilepsy surgery, and discuss possible underlying mechanisms. [Published with video sequences].
