Characteristics of the patients: clinical and electrographic features recorded outside the MRI

Pts	Age (year)	Epilepsy type	Seizure semiology	Age of first seizure (year)	Scalp EEG recordings outside the scanner	Antiepileptic drugs	Seizure frequency
1	25	R TLE	Rising epigastric aura followed by out-of-breath sensation and loss of consciousness	24	Interictal: RTor RFT spike or polyspike-slow waves Ictal: none	None	Two events in 1 year
2	39	R TOLE	Stroboscopic black and white light in the L visual field, or forced eye-deviation to the L with loss of consciousness	12	Interictal: spikes and spike-slow waves over the R posterior quadrant Ictal: rhythmic burst of spikes over the R T region sometimes spreading over the L side	Carbamazepine 2400 mg, Valproic acid 1000 mg, Clobazam 10 mg	1/month
3	52	TOLE	Before surgery visual distortion of objects and lights with language difficulty and now also associated with auditive distorsion	17	Interictal: independent R and L temporal spikes Ictal: none	Pregabalin 450 mg, Topiramate 300 mg	1/day (at least)
4	23	L TLE	Feeling of familiarity, ‘déjá vu’ or ‘deja vecu’ sensation then loss of contact with staring, lip smacking and swallowing movements (lower limbs movements sometimes)	14	Interictal: L T and R T independent irregular sharp waves or spikes Ictal: not recorded in scalp EEG	Carbamazepine 600 mg, Topiramate 300, Clobazam 20 mg	3–4/day in clusters
5	11	R FLE	Sensation of fear followed by a deep breath movement. He could sometimes scream and turns his head to the left	4	Interictal: R F spike-waves isolated or organized in short burst Ictal: Prolonged bursts of rhythmic bilateral F spike-waves with a clear R predominance	Phenytoin 100 mg, Valproic acid 250 mg	20–30/day
6	33	L CPLE	Somesthesic sensation in the R elbow followed by a slow non-tonic R arm elevation	?	Interictal: polyspikes or poly-sharp waves over the L CP area. Ictal: rhythmic fast activity starting over the L CP regions followed by a spreading over the FT areas	Carbamazepine 1200 mg, Topiramate 75 mg, Clobazam 20 mg	1–3/day
7	26	Bil TOLE	Chest pressure feeling followed by loss of contact, staring, chewing and sometimes R eyes-deviation	9	Interictal: spike and slow waves complexes over TO electrodes bilateral or predominant over the R side Ictal: bilateral slow waves followed by rhythmic fast activity seen synchronously over the posterior temporal regions with a predominance over the R side. Irregular generalized slow waves followed	Carbamazepine 1000 mg, Clobazam 40 mg	1/week
8	23	Bil TOLE	Start to see things smaller and far away from her, then she becomes blind or sees lights forming faces	13	Interictal: synchronous and rhythmic slow wave discharges with intermixed sharp components over both posterior head regions Ictal: prolonged electrographic attack, maximal over both posterior temporal regions with clear predominance over the R side	Clobazam 40 mg, Lamotrigine 500 mg, Phenytoin 300 mg	1–2/week
