Neural locating method

A method of locating a nerve within an intracorporeal treatment area of a subject includes providing a first electrical stimulus at a first location within the intracorporeal treatment area, providing a second electrical stimulus at a second location within the intracorporeal treatment area, and providing one or more additional electrical stimuli at the second location. The first electrical stimulus does not induce a threshold response of a muscle innervated by the nerve, whereas the second electrical stimulus does induce a response of the muscle. The one or more additional stimuli each have a current magnitude less than the first stimulus and are used to determine a minimum current magnitude that is required to induce the threshold response of the muscle at the second location. This minimum current magnitude is then used to determine a distance from the second location to the nerve.
