Magnetic Nerve Stimulation
نویسنده
چکیده
Magnetic nerve stimulation is a noninvasive, noncontact means of exciting nerves. Magnetic stimulators generate eddy currents in tissue by producing a high-amplitude, short-duration magnetic pulse from a small coil located near the tissue. A simple circuit can generate the large coil currents necessary for magnetic nerve stimulation. Careful selection of circuit components is necessary to control the influence of parasitic elements on the stimulus. The spatial distribution of the induced electric field is computed for a simple model system excited by a circular coil. Surface charges are induced at tissue boundaries and significantly affect the total induced field.

Motor responses evoked by transcranial magnetic stimulation OMS) or transcranial electrical stimulation (TCS) can be facilitated by a prior conditioning stimulus to an afferent nerve. Two facilitation periods are described short (SI), when the nerve stimulus is given near 0 to 10 ms after cranial stimulation, and long (LI), when nerve stimulation is given 25-60 ms before the cranial stimula...

متن کاملReview of patient safety in time-varying gradient fields.
In magnetic resonance, time-varying gradient magnetic fields (dB/dt) may stimulate nerves or muscles by inducing electric fields in patients. Models predicted mean peripheral nerve and cardiac stimulation thresholds. For gradient ramp durations of less than a few milliseconds, mean peripheral nerve stimulation is a safe indicator of high dB/dt. At sufficient amplitudes, peripheral nerve stimula...
