1. A nerve monitoring system comprising:
an optical element to connect to a camera;
at least one recording probe and at least one exploratory probe;
processors and memories, wherein the processors are coupled to the memories to perform operations comprising:
in response to communications from the at least one recording probe, indicating proximity of the at least one exploratory probe to a nerve based on a strength of an electrical signal sensed by the at least one recording probe;
in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying a digital marker representing a location of the nerve within a displayed visual field that is generated while the optical element is at a first physical location;
in response to the optical element being repositioned from a second physical location back to the first physical location, recognizing an image that was present within the displayed visual field when the optical element was initially at the first physical location;
in response to recognizing the image that was present on a monitor when the optical element was initially at the first physical location, redisplaying the digital marker within the displayed visual field.
