Abstract
It is well-known that magnetic stimulation is quite promising as a method for transcranial that the induced current parallel to the nerve bundle was most effective for excitation, as estimated from a simple model analysis using the activating function. It should be noted that the perpendicular alignment could also evoke neural responses under a certain condition. The next step will be investigated the characteristics of peripheral nerve excitation for each direction of current induced by magnetic stimulation. We performed the experiment to estimate a focality of magnetic stimulation by using the sciatic nerve removed a bullfrog. We noted how the nerve bundle is affected to the direction of induced current by magnetic stimulation. We confirmed the possibility of nerve excitation in the case that nerve bundle was placed perpendicular to the induced current by experiment using sciatic nerve of bullfrog.
