The study uses a sham-controlled, cross-over design in which each participant receives both active taVNS and sham stimulation in separate sessions. Each participant completes both conditions (active and sham) in a randomized order using a crossover design. Cognitive performance will be assessed before and after each session using standardized tests. The study also explores whether males and females respond differently to taVNS, in order to identify potential sex-related differences in cognitive outcomes.",[28,29,30,31,32,33,34,35],"Cognitive Assessment","Cognition","taVNS","Vagus Nerve Stimulation","Executive Functions","Healthy Participants","Neuromodulation","Sex Differences","NOT_YET_RECRUITING","2025-11-27",{"date":39,"type":40},"2025-12-01","ACTUAL",{"date":42,"type":22},"2025-12",{"date":44,"type":22},"2026-05",{"name":46,"class":47},"Bahçeşehir University","OTHER"]
