Summary:

- The study found that non-invasive vagus nerve stimulation (VNS) can enhance perceptual learning and improve visual discrimination abilities in healthy adults.
- VNS, which involves delivering mild electrical pulses to the vagus nerve, was shown to improve participants' ability to distinguish between subtle differences in visual stimuli, suggesting it could have potential applications in enhancing sensory processing and learning.
- The findings indicate that VNS may be a promising tool for boosting perceptual learning and could have implications for developing non-invasive therapies for conditions involving sensory processing deficits.
