Summary

This study tested whether laser acupuncture on specific body points can change how the nervous system and brain work. 103 healthy adults received laser stimulation on either the Neiguan or Shugu acupoint, and researchers measured heart rate and brain activity. The goal was to understand the underlying mechanisms of this non-invasive technique.

What this could lead to
If successful, this could help explain how laser acupuncture works on the brain and nervous system, possibly leading to better non-invasive treatments.
