tVNS

  • non-invasive transcutaneous auricular vagus nerve stimulation (taVNS) provides the opportunity to study the influence of vagal afferent activation on physiological and cognitive processes by modulating vagal input to the brainstem and higher cortical regions

  • stimulation is applied via electrodes placed on the auricular branch of the vagus nerve, usually at the cymba conchae of the outer left ear

Lab equipment:

  • tVNS® stimulator (latest generation; approved as a medical device in Germany) from tVNS Technologies GmbH 

    • stimulation intensity adjustable up to 5 mA

    • frequency range typically between 1 – 30 Hz

    • pulse width between 200 – 500 µs

  • Ear electrodes designed for auricular placement for optimal contact and comfort

  • Control via tVNS® Research App, allowing programmable stimulation parameters and real-time monitoring
