Abstract:
Tinnitus refers to the perception of one or more sounds in the ear or skull without an external sound source,and subjective tinnitus is only perceived by the patient.The central mechanism of subjective tinnitus is related to both the auditory and non-auditory central nervous system.The main factors of tinnitus production in the central auditory conduction pathway are central gain,increased spontaneous firing rate of neurons,and increased synchronization between neurons.In addition,the somatosensory pathway and the limbic system in the non-auditory central nervous system also have a huge impact on tinnitus.The study of the pathogenesis of subjective tinnitus can provide further research ideas for its diagnosis and treatment.
