METHOD COMPARISON
taVNS vs VNS: Methods, Hardware, and Evidence
Vagus nerve stimulation covers several distinct technologies. The stimulation site and delivery method determine which evidence is relevant.

Three forms of vagus nerve stimulation
01
Auricular stimulation
Transcutaneous auricular vagus nerve stimulation delivers electrical pulses through the skin at selected regions of the outer ear. Published studies vary in ear site, laterality, electrode design, waveform, intensity, session schedule, comparator, and outcome.
The abbreviation taVNS refers to the delivery route. It does not define a single device or a standard dose.
02
Cervical and implanted stimulation
Transcutaneous cervical VNS places an external stimulator at the neck. Implanted VNS uses a surgically placed lead and pulse generator. These methods differ from auricular stimulation in anatomy, hardware, procedure, and regulatory context.
Results from one method do not establish the performance of another. Product evidence remains tied to the device, configuration, population, and intended use studied.
03
Where NeuroThaw fits
NeuroThaw is developing an ear-based taVNS platform. The current public product description does not include final stimulation parameters, market authorization, clinical results, price, availability, or a launch date.
QUESTIONS
Frequently asked questions
Is taVNS the same as implanted VNS?
No. taVNS uses an external ear interface, while implanted VNS uses surgically placed hardware.
Is cervical tVNS the same as auricular taVNS?
No. Both are non-invasive, but the stimulation site and hardware differ.
Can evidence from one VNS method validate another?
No. Evidence is interpreted in relation to the exact method, device, protocol, population, and outcome studied.
