In tinnitus, PET and other functional imaging modalities have shown functional changes not
only in the auditory cortex but also in nonauditory regions such as the limbic, frontal, and …

Tinnitus is the percept of sound that is not related to an acoustic source outside the body. For
many forms of tinnitus, mechanisms in the central nervous system are believed to play an …

Cerebral 18F‐deoxyglucose positron emission tomography (FDG‐PET) has shown altered
auditory pathway activity in tinnitus. However, the corresponding studies involved only small …

Subjective tinnitus is an auditory phantom perception that may arise from any aberrant
signal within the auditory system. Further processing of this signal and the conscious …

Recent data suggest that chronic tinnitus is a “phantom auditory perception” caused by
maladaptive neuroplasticity and subsequent hyperactivity in an extended neuronal network …

Recent advances in functional imaging have opened new possibilities for understanding
tinnitus. Especially, positron emission tomography (PET) has been increasingly used in the …

Purpose: The neural mechanisms that give rise to the phantom sound of tinnitus have not
been fully elucidated. Neuroimaging studies have revealed abnormalities in resting-state …

Tinnitus is characterized by the perception of sound in the absence of an external auditory
stimulus. The network connectivity of auditory and non-auditory brain structures associated …

Tinnitus is the perception of phantom sound without an external auditory stimulus. Using
neuroimaging techniques, such as positron emission tomography, electroencephalography …

Conclusion: Unilaterally increased metabolic activity within the primary auditory cortex
(PAC) represents a robust finding in tinnitus patients. Targeting these hyperactive areas with …
