The aim of this study was to investigate whether fMRI responses can be measured during median nerve activity. The median nerve was stimulated at the threshold of action potential generation using transcutaneous electrical nerve stimulation (TENS). Evidence of fMRI responses in the median nerve during wrist stimulation by TENS was observed at relatively high stimulation frequencies (2.5 and 3.5 Hz).
