Elevated activity was observed in cingulo-opercular cortex during incorrect word recognition trials (A) and in the anterior insula, inferior frontal gyrus, and orbitofrontal cortex, bilaterally (B) for trials with reduced speech intelligibility (red: pUNC = 0.01, yellow: overlap with Vaden et al., 2013, conjunction pUNC < 0.0001; each cluster had extent-based pFWE < 0.05).
