Summary

This study tests whether a mild electrical pulse to the ear—called transcutaneous auricular vagus nerve stimulation—can improve decision-making and problem-solving. Researchers will compare results in healthy adults, people with mild cognitive impairment, and those with Parkinson's disease. The goal is to understand how this non-invasive technique affects brain networks, not to treat or cure any condition.
