A small signal.
A powerful pathway.
The vagus nerve helps regulate the body’s “fight or flight” and “rest and relax” responses. taVNS delivers mild electrical stimulation through the ear.
Gentle stimulation
The earpiece delivers light electrical pulses.
Vagus activation
Signals travel along the auricular vagal pathway.
Restoring balance
Research explores autonomic balance and neuroplasticity.
