Tinnitus: perspectives from human neuroimaging.
Level 5 - mechanism / opinion, no new human data
Narrative review of neuroimaging literature without systematic search or meta-analytic methodology
PubMed 26373470 · doi:10.1038/nrn4003
What was done
This review evaluates human neuroimaging literature investigating central nervous system adaptations associated with tinnitus, focusing on functional and structural alterations following peripheral deafferentation.
What was found
The abstract reports no quantitative metrics or statistical values. It summarizes that neuroimaging studies demonstrate functional and structural brain alterations across distributed auditory and non-auditory regions in individuals with tinnitus.
Why it matters
It frames tinnitus not merely as an ear disorder, but as a condition involving widespread central auditory and non-auditory neural network changes.
Limits
The abstract describes a narrative review rather than a systematic review or meta-analysis and provides no quantitative data. The authors explicitly note that existing studies in the field suffer from small sample sizes, lack of replication, and incomplete clinical characterization of patient subtypes.
