The role played by the ANT in human epileptic seizures and the mechanisms leading to the anti-seizure effects of ANT-DBS have not yet been fully elucidated. This is the first report of recording interictal and ictal activity in the human ANT. DBS electrodes were implanted in the ANT of six pharma- coresistent patients with temporal and extratemporal epilepsies who had not responded to vagus nerve stimulation. Interictal and ictal video-EEG was recorded via the DBS electrodes before the electrodes were internalized and a neurostimulation device was implanted. Interictal high frequency oscillations (HFO) of 80 to 240 Hz, in one case of 500 Hz, were recorded in four patients. Eight clinical seizures in four patients were recorded; a robust broad-band increase of power occurred in the early phases of all seizures. In two patients, the ictal changes preceded the clinical symptoms. No interictal epileptiform discharges were recorded; early epileptiform pattern preceding the clinical onset was recorded in one seizure.Based on our recordings of HFO, of early ictal EEG modifications, and of occurrences of ictal epileptiform pattern, we suggest that the ANT may participate actively in the network elaborating seizures in human epilepsies.
