Comparison of brain activities between the HS and GERD patients. (a) anteroposterior image, (b) coronal image, (c) transverse image. The cold color represents the fALFF of brain regions which are lower in GERD than HS. The fALFF of GERD is significantly lower in the bilateral precuneus and PCC compared with HS (p < 0.01 and cluster level >90 voxels).
