Subjective tinnitus is a distressing condition characterized by the sensation of sound or noise in the absence of internal or external stimuli. Research indicates that tinnitus may develop due to maladaptive plastic changes in the auditory cortex and limbic system. These changes can be targeted using safe and noninvasive brain stimulation techniques like transcranial direct current stimulation (tDCS). TDCS alters the excitability of the cortex using a weak direct current and may lead to long-term plastic changes, making it a potential therapeutic tool for the treatment of tinnitus.
