Transcutaneous vagus nerve stimulation (tVNS) has been reported on its effect to reorganize the sensory neural network in the central nervous system, similar as the observations in the traditional invasive vagus nerve stimulation. Very few studies have examined the impact of tVNS on the plasticity of the motor neural network. This exploratory study was aimed to investigate the effect of tVNS on the motor neural network manifested in laryngeal muscle flexibility and activities during word-level p...
