Alpha activity in networks involved in visual processing.
What the study found
Researchers compared resting EEG in 21 people with visual snow syndrome and 21 matched controls. They found lower alpha power in temporal and parietal regions, while the primary occipital sites tested did not differ significantly.
What this tells us
The results suggest altered activity in networks involved in visual processing and filtering. This research concerns visual snow syndrome, rather than every type of visual processing difficulty.
