Other speakers discuss the vagus nerve because of its "Parasympathetic Facilitation" and "Sympathetic Inhibition" effects on the nervous system and the systemic effect. There is too much vagus involvement to mention in a manual.
XLR8 works great, but you may see additional benefits with GVL or EVRL. For two decades, thousands of practitioners have used the standard setting A1 = 9, A2 = 16, B1 = 42, and B2 = 53 with great results. More recent speakers for Erchonia have these as their "go-to" for the vagus nerve.
If you want to learn muscle testing (or you already do AK-type muscle testing, not just ortho/neuro), the Advanced Laser Video has many of the "activation method protocols" of the Vagus, "Parasympathetic Facilitation," and "Sympathetic Inhibition" that cannot be written in this manual. It requires a video.
Also, pulses/Hz to slow the brain down can be very beneficial as the body works as a system. So, Delta, theta, and even low beta waves can help facilitate parasympathetic. Using the mentioned settings while tracing the pathway would make sense for general application by some clinicians, but implementing the variety of specific "activation" methods that will enhance the physiological response significantly is my preferred amplifier. With many great options, if you are a muscle tester, you can test “the body’s choice,” testing specifically for the personal needs of that appointment.
If your laser has a linear scan function, it promotes an additional advantage to body rhythms. If not, proceed with confidence!
