P3-6-03. Visualization of nerve impulse traveling along the brachial plexus after ulnar nerve stimulation using 132ch SQUID magnetoneurography system

Using 132ch superconducting quantum interference device (SQUID) magnetoneurography sensor system, we succeeded in visualizing nerve impulse traveling along the brachial plexus (BP) after median nerve stimulation and propagating into the C5–C8 intervertebral foramen with participant's X-ray imaging. Here we analyzed the nerve impulse traveling along BP following ulnar nerve stimulation at the wrist.Magnetoneurogram following wrist stimulation were measured over BP from 5 healthy volunteers. Somatosensory evoked potential (SEP) was simultaneously measured at Erb's point for making sure to deliver supramaximal stimulation.
