Study 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.
Primary Outcome
d' is a signal-detection sensitivity index-how well participants discriminate old (studied) from new (unstudied) items, independent of response bias. Computed as d' = Z(hit rate) - Z(false-alarm rate) from the old/new recognition memory test. Primary analysis is within-person Δhigh-confidence d' (based on "sure old" responses in the 4-point "sure old", "unsure old", "unsure new", "sure new" scale, Δ = active - sham) and Δoverall d' (based on "sure old" and "unsure old" responses).
