Non-invasive transcutaneous vagus nerve stimulation during memory retrieval enhances recollection of emotionally salient memories.

Although the main effect of Stimulation was not significant, β = − 0.01, SE = 0.05, t(104.38) = − 0.17, p = 0.87, the interaction between Stimulation and Category approached significance, β = 0.08, SE = 0.04, t(73) = 1.94, p = 0.056 , suggesting a trend toward a more liberal response bias for unpleasant images under taVNS compared to sham stimulation.
