Summary

In this one-visit, randomized, double-blind, sham-controlled trial, we plan to use a novel concurrent transcutaneous auricular neurostimulation (tAN) paradigm during functional magnetic resonance imaging (fMRI) paradigm in 96 individuals to determine whether tAN administered to two cranial nerves simultaneously produces greater neurophysiologic effects than stimulating solely to the auricular branch of the vagus nerve (ABVN) or the auriculotemporal nerve (ATN; branch of trigeminal nerve) alone. Within the MRI scanner, each participant will be connected to a series of electrodes that stimulate 4 targets (ABVN only, ATN only, ABVN plus ATN, and Sham).

Conditions

  • Auricular Stimulation

Interventions

DEVICE

Transcutaneous Auricular Neruostimulation (tAN)

The intervention we are studying is called transcutaneous auricular neurostimulation (tAN). tAN is simply electrical nerve stimulation administered at the ear which targets both the auricular branch of the vagus nerve (ABVN) and the auriculotemporal nerve (ATN, a branch of the trigeminal nerve).
