The microneurographic technique makes it possible to record the unitary activity of sensory neurons in humans.
This technique involves inserting a tungsten microelectrode manually into a superficial nerve, transcutaneously.

It is very delicate and we are the only one to use it in France.
Our recordings are performed at the level of the peroneal nerve at the back of the popliteal hollow or at the level of the median nerve on the inner side of the arm (see figure below).
