This study shows that transcutaneous vagus nerve stimulation (tVNS) improves perceptual decision accuracy by enhancing evidence accumulation, particularly when applied early in a task.

This study shows that transcutaneous vagus nerve stimulation increases corticospinal excitability and pupil size during active stimulation but not after, with distinct temporal dynamics between the two effects.

This study uses tVNS to investigate the role of the LC-NE system in perceptual decision-making, finding it improves accuracy without affecting reaction times, supporting the gain hypothesis.
