Micromagnetic stimulation (µMS) dose-response of the rat sciatic nerve.

This work reports that µMS can successfully activate the sciatic nerve in a dose-dependent manner. The MagPen probe, unlike electrodes, does not have a direct electrochemical interface with tissues rendering it much safer than an electrode. Magnetic fields create more precise activation than electrodes because they induce smaller volumes of activation. Finally, unique features of µMS such as orientation dependence, directionality and spatial selectivity have been demonstrated.
