This study tests how a special technique called transcutaneous vagus nerve stimulation (tVNS) affects motor learning, or how we learn to move better. In this study, older adults will practice finger movements with and without tVNS. tVNS involves a gentle electrical signal sent to a nerve in the ear. Participants will be split into two groups: one will get the real tVNS, and the other will get a pretend version (sham), during training. The study will measure how well participants can control their finger movements before and after training.
- Time Commitment: 4 lab sessions
- Eligibility: Ages 65-84, healthy, right-handed
- Requirements: No electrical stimulation during tests
