FC analysis from occipital lobe to the whole brain voxels in NDPH and HC groups. A (a) The schematic diagram of the seed (left superior occipital gyrus). (b) Compared with HCs, patients with NDPH showed significantly decreased FC between the left superior occipital gyrus and right lingual gyrus, right fusiform gyrus. (c) and (d) represented FC values between the seed and right lingual gyrus, right fusiform gyrus respectively in HCs and patients with NDPH. B (a) The schematic diagram of the seed (right middle occipital gyrus). (b) Compared with HCs, patients with NDPH showed significantly decreased FC between the seed and bilateral lingual gyrus, right calcarine, right fusiform gyrus. (c) to (f) represented FC values between the seed and bilateral lingual gyrus, right calcarine, right fusiform gyrus respectively in HCs and patients with NDPH. C (a) The schematic diagram of the seed (left inferior occipital gyrus). (b) Compared with HCs, patients with NDPH showed significantly decreased FC between the seed and bilateral lingual gyrus, left fusiform gyrus, bilateral inferior occipital gyrus, right middle occipital gyrus and increased FC between the seed and medial superior frontal gyrus. (c) to (i) represented FC values between the seed and bilateral lingual gyrus, left fusiform gyrus, bilateral inferior occipital gyrus, right middle occipital gyrus, medial superior frontal gyrus respectively in HCs and patients with NDPH. D (a) The schematic diagram of the seed (right inferior occipital gyrus). (b) Compared with HCs, patients with NDPH showed significantly decreased FC between the seed and bilateral lingual gyrus, bilateral fusiform gyrus, left inferior occipital gyrus. (c) to (g) represented FC values between the seed and bilateral lingual gyrus, bilateral fusiform gyrus, left inferior occipital gyrus respectively in HC group and patients with NDPH. Notes: The color bar showed t-values of the two-sample t-tests on FC.
