Summary

This study looked at how a type of ear acupuncture (using tiny press needles) changes brain connections and nerve activity in 40 healthy adults. Researchers used brain scans to see if the acupuncture affects areas linked to emotion and body awareness, similar to vagus nerve stimulation. The goal was to understand how this technique might help with conditions like insomnia and depression in the future.
