Transcutaneous vagus nerve stimulation (tVNS) is a non-invasive technique that applies electrical currents through surface electrodes at selected locations to reorganize the brain neural network based on neuroplasticity. The therapeutic effect of tVNS has been reported related to the sensory neural network, but few studies are on the motor neural network. We hypothesized that when applying the tVNS to the recurrent laryngeal branch of the vagus nerve, the laryngeal muscles responsible for speech will become more flexible, and their motor activities will be enhanced. To examine this hypothesis, Chinese lexical tones were adopted to be imitated by the healthy English native speakers. Preliminary results indicated the positive tVNS effect and its potential clinical application.
