Activation of the Cognitive Control Network. (a), (b), SPM-T maps from the present study indicating activation of the CCN by the n-back task in the healthy control group (a) and the chronic tinnitus group (b), with the circled region suggesting reduced activation of the right middle frontal gyrus (rMFG) in the chronic tinnitus group. (c) We performed an automated reverse inference meta-analysis using NeuroSynth⁶⁷ on 2633 fMRI studies that were identified using the search term ‘cognitive’. The results highlight broad network activation within nodes of the cognitive control network (CCN), anchored in bilateral dorsolateral prefrontal cortex and posterior parietal cortex²⁰.
