Fascinating article…by Nancy Bonk on Health Central
“Another study used a white moving dot pattern on a black background to visually stimulate the subjects, showing the Migraine group had a stronger activation in the middle temporal complex (motion sensitive region) compared to the non-Migraine group. These studies support the idea that Migraineurs have enhanced reaction to light and motion stimuli in addition to having thicker cortex in the visual motion processing centers of the brain compared to non-Migraineurs.”
Yep… that relation I can understand since I am really hypersensitive to both light and motion. Both of which persistent beyond the migraine but are obviously worse with one.
“Dr. Schwedt rounded out his session discussing how a Migraineur “co-processes” different stimuli and that Migraine itself is multisensory integration that has “gone wrong.” He went on to explain what multisensory integration is:
“sensory-specific brain responses and perceptual judgments of incoming sensory stimuli which concern one sense may be modulated by relations with other senses.”
Again, isn’t that interesting to note? How the stimulus gets tangled up? Makes a lot of sense doesn’t it? Certainly, it seems that our senses are hyper-aware during a migraine. That super sense of smell, photophobia, super hearing… too much of everything. And I am definitely photophobic and have been for decades. And odors… but that is an FM thing too.
