Tang L, et al. - Researchers aimed at assessing whether or not synchronous neural activity changes were measured with the regional homogeneity (ReHo) method in acute eye pain (EP) patients. Acute EP patients showed significantly lower ReHo values in the left precentral/postcentral gyrus (Brodmann area [BA]3/4), right precentral/postcentral gyrus (BA3/4), and left middle frontal gyrus (BA6) compared with healthy controls. Thereby suggesting altered synchronous neural activities in many brain regions among acute EP patients, including somatosensory regions.
