All recruiting trials (3)
-
Mapping TMS‑induced light flashes (phosphenes) while tracking eye movements
Researchers will test whether single‑pulse TMS produces brief light flashes and how eye movements change where adults with visual snow, color blindness, and healthy volunteers see those flashes.
-
Brain function and visual adaptation in people with and without Visual Snow
This project will test whether brain activity and responses to visual stimuli differ between adults with Visual Snow Syndrome, adults with migraine, and healthy adults.
-
7T MRI scans for migraine, visual snow, and epilepsy
This project will use high-field 7T MRI to try to find microstructural and network differences in people with migraine, visual snow, or drug‑resistant epilepsy and in healthy volunteers.
