Fig. 2From: Functional connectivity of the visual cortex differentiates anxiety comorbidity from episodic migraineurs without auraa-c The brain regions showed significant group differences in functional connectivity based on the right LG among the three groups (MwoA-A, MwoA-OA and HCs). The significance threshold was set at voxel-level p < 0.005 (Bonferroni corrected) with a 40-voxel extension. Cool color represents decreased strength of functional connectivity and warm color represent increased strength of functional connectivity.
