About this study
This study plans to learn more about how stimulating the vagus nerve through gentle electrical stimulation applied to the ear can affect decision-making, problem-solving, and other thinking abilities. This process, called transcutaneous auricular vagus nerve stimulation (taVNS), could help improve brain function in both healthy individuals and people with Parkinson's disease (PD).
