When suffering from a migraine, the last thing you may associate it with is excitement. But a recent study suggests that the brains of those who have the intense headache appear to be “hyper-excitable.” Researchers from the University of Birmingham and Lancaster University, both in England, set out to test a theory that a part of the answer lies in the visual cortex.
Participants further underwent an electroencephalogram test, which researchers used to track and record participants’ brain wave patterns when visual stimuli were presented. Both tests resulted in researchers finding a greater response in the visual cortex among migraineurs when participants were presented with the gratings.
