1. A nerve mapping system comprising:
a computer system configured to:
cause delivery of sequential variable multi-polar stimulation to electrodes of a grid array of electrodes according to a plurality of stimulation configurations to scan the grid array and elicit evoked potential responses, wherein the plurality of stimulation configurations include at least mono-polar, bi-polar, and tri-polar stimulation configurations of different electrodes of the grid array, and wherein the electrodes are positioned on a surface of an instrument configured to be inserted into a tissue site of a patient to map locations and proximities of neural structures in the tissue site; and
receive the evoked potential responses and combine information gathered based on the evoked potential responses to enable nerve mapping.
