Figure 4. Source-localized correlation analysis between the percentage improvements in the NRS of tinnitus perception and the pre-TRT resting-state qEEG data.
The percentage improvement in NRS tinnitus perception correlated positively with the pre-TRT localized activities of the rACC and the right DLPFC (BAs 9 and 10) (i.e., the theta frequency band); and the activities of the bilateral rACC, bilateral pregenual ACC, and right DLPFC (i.e., the alpha 1 band); and the activities of the left orbitofrontal cortex (BA 11) and right medial frontal cortex (i.e., the gamma band).
