Abstract：[Objective]To study central functional network connections and their alterations in tinnitus patients using fMRI. Meth-ods fMRI was performed in 18 tinnitus patients and 20 controls. Regional consistency (regional homogeneity or ReHo value) and functional network connection alterations were compared between the tinnitus patients and controls. Results Tinnitus pa-tients showed increased ReHo values in gyrus frontalis inferior and decreased ReHo values in anterior lobe of cerebellum in comparison with the controls. The regions with decreased ReHo values were bilateral inferior frontal gyrus, middle frontal gy-rus and anterior cingulate. Conclusions Abnormal fMRI changes in auditory cortex and non-auditory cortex are present in tin-nitus patients. The severity of tinnitus is linearly correlated to the changes in some brain regions. fMRI may be useful in evalu-ating tinnitus.
