Alpha rhythm power and the effect of photic stimulation in migraine with brain mapping.
The topographic maps of 50 patients suffering from migraine with or without aura were compared to the brain maps of 20 normal controls and 20 patients with tension-type headaches. Only the migraine group showed a significant decrement of alpha rhythm power, during rest with eyes closed, at the posterior areas of the brain, and a significant increment of alpha power at the same regions during IPS at 20 c/sec.
