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).
