A Electroencephalogram of Patient 1. Before treatment (left), generalized spike-wave complexes are seen; focal spikes in the right frontal and left temporal areas and photoparoxysmal responses were noticed (data not shown). After treatment (right), amplitude of spikes is decreased. Electrodes placement: International 10–20 + T1/T2. Sampling rate: 500 Hz. AC amplifier low frequency filter: 0.08 Hz. B Arterial spin labeling images of Patient 1, post labelling delay of 1800 msec. Before treatment (left), the right cerebellar hyperperfusion and the left thalamic hypoperfusion are shown. After treatment (right), these abnormalities are not detected
