Frequently Asked Questions (FAQs)

General tVNS FAQs

What is Vagus Nerve Stimulation Used For?
Vagus Nerve Stimulation has been used to treat epilepsy and depression. This is done with implanted Vagus Nerve Stimulators. Scientists are now researching non-invasive Vagus Nerve Stimulation using devices that connect to the ear. This is being used to investigate other possible benefits of VNS.
Can tVNS Help with Migraines?
Yes. There is some data that indicates people suffering from headaches, cluster headaches and migraines may see some benefit from the use of tVNS; for example see this scientific studyHowever, as reported, actual results may be dependent on the individual and may vary.
Where is the Vagus Nerve Stimulated?
The Vagus nerve is named after the greek word meaning "wander". This is because anatomical studies revealed that it travels a wide path throughout the human body. From the stomach, lungs, heart and brain but also to the ears. So the easiest location to stimulate the Vagus Nerve happens to be in the ear.  Specifically the tragus of the left ear.

tVNS Device FAQs

Can I Wear a Hearing Aid When Using tVNS
You should remove your hearing aid before using tVNS. If you have an implanted hearing device then you should not use tVNS.
What is the "vaseline" for?
It looks a bit like vaseline but it's actually conductive paste. You put a little smudge on the gold electrodes of the clip before clipping the clip to your tragus.The conductive paste greatly reduces the resistance between your skin and the electrical circuit.The effect of using paste is to greatly reduce the sensation of the stimulation. In our tests users were able to stimulate at much higher levels without discomfort when using this conductive paste.
What's the difference between vagusnet and a TENS machine?
Tens machines are voltage-controlled, while the vagusnet stimulator is a current-controlled device. We advise against the use of standard TENS machine in the stimulation of the vagus nerve. To learn why, read our blog post on the subject.
