Migraine sufferer's cerebral visual cortical layer 'overexcited'

causes of common migraines are complex. Migraine sufferers appear to be "overexcited" in the visual cortical sphere of their brains, according to a new British study published on Monday. More in-depth research in this area will help to find better ways to prevent migraines.
migraines are a common type of headache, and many times the stimulation of sound and light exacerbates the symptoms. Some previously thought this might be related to changes in nerves or blood vessels in the brain, but the medical community has yet to determine the cause of migraines.
at the University of Birmingham and Lancaster University reported in the international academic journal Neuroimaging: Clinical that they recruited 60 volunteers to take part in the trial, half of whom suffered from migraines. In the experiment, the researchers showed the volunteers a striped grid test map and asked them if they felt uncomfortable after looking at it, and in further tests, they were asked to take an electro-encephalogram test while looking at the map.
found that volunteers with migraines had a more pronounced response to the visual cortical layer of the brain after seeing a striped grid test. The visual cortical layer refers to the part of the cerebral cortical layer that is primarily responsible for processing visual information.Dr Ali Mazahri of the University of Birmingham, one of the authors of the report, said the study showed that the visual cortical cortical layer of migraine sufferers is likely to change abnormally in the processing of external information, but
"this may only be part of the reason, as similar reactions occur in some volunteers who do not suffer from migraines but are sensitive to visual stimuli."
next step for the team will be to delve deeper into the phenomenon and conduct longer-term observations to better understand the causes of migraines. (Source: Xinhua News Agency, Zhang Jiawei)
