Abstract Transcutaneous vagus nerve stimulation (tVNS) offers a non‐invasive method to enhance noradrenergic neurotransmission in the human brain, thereby increasing cognitive control. Here, we investigate if changes control induced by tVNS are mediated through locus coeruleus‐induced modifications of neural activity anterior cingulate cortex. Young healthy participants engaged simple task focusing on response inhibition and more complex that involved both working memory, inside magnetic resonance imaging scanner. The tasks were executed using randomized within‐subject design, with undergoing auricular sham separate sessions. significantly changed performance reflected greater propensity respond. Furthermore, observed significant increase cortex during under tVNS. Functional connectivity analyses revealed positive coupling between coeruleus cortex, however, this was not modulated findings suggest can modulate While these effects an impact key region conflict monitoring control, behavioral indicative shift bias rather than enhanced
