Does stimulus frequency modulate brainstem fMRI response to respiratory-gated transcutaneous auricular vagus nerve stimulation?
Stimulation frequency is a significant modulator of brainstem fMRI response during transcutaneous auricular vagus nerve stimulation.
Our fMRI results support previous localization of taVNS afference to pontomedullary aspect of NTS in the human brainstem, and demonstrate the significant influence of the stimulation frequency on brainstem fMRI response.
Sclocco et al. (Fri,) studied this question.
