Fig. 3From: Multi-frequency analysis of brain connectivity networks in migraineurs: a magnetoencephalography studyNumber of migraineurs and controls in different functional connectivity patterns in 0.1–1 Hz. Migraineurs have significantly higher odds of functional connectivity in the frontal area compared with controls. The blue bars indicate that excitatory connections are present in the frontal area. The orange bars indicate that no excitatory connections exist in the frontal areaBack to article page
