Investigating Brain Function in People With and Without Visual Snow Syndrome Using Adaptation to Visual Stimuli

Presentation of visual stimuli to quantify the appearance of visual snow or its effects in the visual system of the brain.

Administration of clinical assessments and questionnaires to gather information about visual and mental symptoms, cognitive, and sensory function.

7 tesla fMRI data will be acquired during visual paradigms designed to measure neural responses with and without adaptation.

7 tesla MRS data will be acquired to quantify the concentrations of different brain chemicals in brain regions including visual cortex.
