Alterations of the alpha rhythm in visual snow syndrome: a case-control study

ConclusionsOur main finding was a decreased power spectral density in the alpha band over parietal and temporal brain regions corresponding to areas of the secondary visual cortex. These findings complement previous functional and structural imaging data at a electrophysiological level. They underscore the involvement of higher-order visual brain areas, and potentially reflect a disturbance in inhibitory top-down modulation. The alpha rhythm alterations might represent a novel target for specific neuromodulation.Trial registrationwe preregistered the study before preprocessing and data analysis on the platform osf.org (DOI:https://doi.org/10.17605/OSF.IO/XPQHF, date of registration: November 19th 2022).Graphical Abstract
