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.
将50例伴有或不伴有先兆的偏头痛患者的地形图与20例正常对照者及20例紧张型头痛患者的脑图进行比较。仅偏头痛组在闭眼休息时大脑后部区域的α节律功率显著降低，而在每秒20次的ips期间同一区域的α功率显著增加。
