Fig. 8From: Attenuated alpha oscillation and hyperresponsiveness reveals impaired perceptual learning in migraineursThe average post-stimulus alpha power change between 1st half and 2nd half of the experiment for MF condition. A Cluster-based permutation analysis on the post-stimulus interval (0 to 1 s after the MF grating onset) revealed an enhanced alpha suppression in 2nd half of the experiment for migraine between 350 and 700 ms after the stimulus onset. B The significant channels (highlighted with *) were distributed over the central-parietal regions. C There was no significant difference in alpha suppression between migraine and control for both 1st half and 2nd half of the experiment. D The average alpha suppression (600 – 1000 ms after the stimulus onset) for migraine was stronger in the 2nd half in the central-frontal region. The significant cluster (highlighted with an asterisk (*)) indicated the maximum differences in alpha suppression between migraine and controlBack to article page
