Ear stimulation to Lower Blood Pressure: RAVANS or TAVNS
I’ve been looking at vagal activity with ear stimulation, or transcutaneous auricular vagal nerve stimulation (TAVNS)in the clinic for several years. As readers know, acupuncture calms the stress response by increasing vagal activity. TAVNS should increase vagal activity also. If I can show this, it would give me added confidence in having people use a…

This study is relevant because of the RAVANs technology that synchronizes TAVNS with expiration. In these authors study they use 100Hz which may nor may not be optimal, just as tragus and cavum concha may not be optimal. But nonetheless, they saw now difference in HRV. TAVNS is running up against real problems in showing…

Read MoreTranscutaneous Vagal Nerve Stimulation (RAVANS) fMRI in Migraineurs
I have been exploring Transcutaneous Vagal Nerve Stimulation (tVNS) by way of auricular cymba concha stimulation as an adjunct to acupuncture treatment for over two years. This article by friend of blog Vitaly Napadow, looks at TVNS in migraineurs. They up the ante a bit by synchronizing the stimulation (30hz, non-painful stimulation) with exhalation. This…
