Fig. 5

FC analysis from right thalamus to the whole brain voxels in NDPH and HC groups. A The schematic diagram of the seed (right thalamus). The brain region marked in blue represents the right fusiform gyrus. B The schematic diagram of significant FC differences. Compared with HCs, patients with NDPH showed significantly increased FC between the seed and bilateral cuneus, left calcarine, right superior occipital gyrus. C (a) to (d) represent FC values between the seed and bilateral cuneus, left calcarine, right superior occipital gyrus respectively in HCs and patients with NDPH. Notes: The color bar showed t-values of the two-sample t-tests on FC. Abbreviations: L, left; R, right; Sup, superior; FC, functional connectivity; NDPH, new daily persistent headache; HC, health control
