Hi Dr. Russell,
There is FMRi research showing that needling effects the limbic system, which is one area for anxiety and the best way to access this area would be through the homeostatic points so do as many of those as you can and leave the needles in for 20 min ( based on a research paper stating the ANS is stimulated up to 21 min then after the effect reduces.
Hope that helps!
Dr. Frank
