Abstract
A method for locating neural tissue in a patient body may involve: advancing a probe along a natural tissue interface between the neural tissue and another tissue in the body, the probe having a first surface oriented toward the neural tissue and a second surface oriented away from the neural tissue; delivering a first electrical current to a first electrode along the first surface of the probe; delivering a second electrical current to a second electrode along the second surface of the probe; and verifying that the first surface of the advanced probe remains oriented toward the neural tissue and the second surface remains oriented away from the neural tissue by monitoring neural response to the first and second electrical currents.
