Coloured circles show where the strength of various different rhythms of brain activity correlated with the strength of the tinnitus the patient was hearing
"A number of models - and therefore treatment approaches - have aimed to pinpoint a particular part of the auditory cortex, that relates to the frequency being heard, either by targeting it physically in the brain, or with sounds at that frequency.
"But our results suggest that... it's a much wider part of the auditory cortex, and the brain, that's implicated in tinnitus, So these strategies might have to be revised or reconsidered a bit."
