#$%^&*AU2013204803A120130509.pdf#####Abstract A surgical system for stimulating nerves and monitoring EMG responses to the nerve stimulation comprises a control unit including a color display device and being 5 configured to compute information for output to the color display device, which is indicative of e.g. nerve proximity, nerve direction, nerve pathology, stimulation level, EMG response data, pedicle integrity, advance or hold instructions, and instrument in use. A connector module comprises a plurality of EMG response channels and an electrical connection for at least one nerve stimulation instrument. A plurality of pairs of EMG 10 electrodes are connectable to the plurality of EMG response channels and are mountable proximate to selected leg muscles. A first stimulation instrument comprises a dilator tube and a stimulation element while a second stimulation instrument comprises a pedicle probe that delivers the stimulation signal when advanced into a pedicle opening formed in the spine. The pedicle probe comprises a probe tip member and handle with a user15 actuatable button to activate the stimulation signal for delivery by the screw test probe. 33
