Charts of Spearman’s correlation, showing significant correlations between the parameters of network and clinical characteristics in the migraine patients in viewing the positive emotional stimuli (green point), negative emotional stimuli (blue point), and neutral stimuli (orange point). During positive emotion stimuli, the migraine history showed a negative correlation with C in the delta frequency. During negative emotion stimuli, the history of migraine showed a negative correlation with L in the beta band and with S in the gamma band, and the attack frequency of migraine also showed a negative correlation with L in the theta band. During the neutral emotion stimuli, the migraine history and duration showed a negative correlation with S in the delta and gamma frequencies, respectively
