Fig. 6From: Abnormal functional connectivity under somatosensory stimulation in migraine: a multi-frequency magnetoencephalography studyCharts of Spearman’s correlation showing significant relationships between the parameters of network and clinical characteristics in migraineurs. Duration of migraine attacks shows a negative correlation with network strength in the 4–8 Hz range. Migraine attack frequency shows a positive correlation with path length in both the 1–4 Hz and 30–80 Hz frequenciesBack to article page
