Fig. 1From: Avoid or seek light – a randomized crossover fMRI study investigating opposing treatment strategies for photophobia in migraineIndividual habituation curves in the primary visual cortex (V1), illustrated for patient P07. Visual activation was induced by a flickering light task (10 runs, block design, FWE-corr. 0.05, activation displayed in red to yellow). Mean beta values within the V1 region of interest (blue) were extracted for each run and linearized using the natural log transform, resulting in uncorrected individual habituation curves per sessionBack to article page
