FC analysis from bilateral postcentral gyrus to the whole brain voxels in NDPH and HC groups. A (a) The schematic diagram of the seed (left postcentral gyrus). (b) Compared with HCs, patients with NDPH showed significantly decreased FC between the seed and right postcentral gyrus, right precentral gyrus. (c) and (d) represented FC values between the seed and right postcentral gyrus, right precentral gyrus respectively in HC group and patients with NDPH. B (a) The schematic diagram of the seed (right postcentral gyrus). (b) Compared with HCs, patients with NDPH showed significantly decreased FC between the seed and bilateral precentral gyrus and left postcentral gyrus. (c) to (e) represented FC values between the seed and bilateral precentral gyrus and left postcentral gyrus respectively in HC group and patients with NDPH. Notes: The color bar showed t-values of the two-sample t-tests on FC. Abbreviations: L, left; R, right; FC, functional connectivity; NDPH, new daily persistent headache; HC, health control
