Synopsis

Keywords: Brain Connectivity, fMRI (resting state), tinnitus

As a common disorder, the development of tinnitus deserves the attention of neuroscientists. The present study combined fractional amplitude of low-frequency fluctuations and functional connectivity to explore brain functional abnormalities in transition from recent-onset to chronic tinnitus. Abnormal intraregional neural activity and functional connectivity were observed in the left middle frontal gyrus and left dorsolateral superior frontal gyrus during the development of chronic tinnitus, and these regions are major components of attention network and executive control network. These findings provide us with a better understanding of the aberrant brain changes and neuropathophysiological mechanisms of the progression of tinnitus.
