Sponsor: Stanford University
Summary
The aim of this study is to determine whether non-invasive vagus nerve stimulation enhances memory formation in cognitively healthy older adults and whether the effects of stimulation depend on gut and brain health.

Interventions
Transcutaneous Auricular Vagus Nerve Stimulation (taVNS)
Non-invasive vagus nerve stimulation will be delivered with a well-validated device. taVNS delivers stimulation on the left ear, with the placement of the stimulating electrode differing between the active and sham conditions. Stimulation will occur during each learning trial (total of 30 trials per phase).
