Metabolism dissorder in the cerebral brain.

And on the migraine attack are connects of nerve cells in the brain s stem and in the middle brain are very activity, and by migraines tests without aura is on the time for attack with positron emission tomography.This method allows to measure a local blood current in the brain and gives his image.And by this we can to guess,that there are having cells of brain, which affects for migraine attack or supports his migraine generator, and still discussing a question about,that functional destroys of hypothalamus are affecting for migraine beginning attacking.
And bad blood circulation in the cortex of cerebral brain in the having of migraines aura are knew, and in visual aura as lowering mass of circulating blood as oligemia flows with a speed on 3-4 mm/minute of the back sides a cerebral brain,where having a vision cortex in the front. Oligemia is a consequence for happening with a same speed of lowering electric activity of cells a cerebral brain, as cortical spreading depression, and this appearance observed in  the animals.And casely in the doing for positor emission tomography are measured also a begin migraine attack without aura, and was registered a same change of blood current, spreading from a back sides of head brain in the front.
