Neuro-navigation is the set of computer-assisted technologies used by neurosurgeons to guide or “navigate” within the confines of the skull or vertebral column during surgery. Neuro-navigation provides the ability to relate the position of a real surgical instrument in the surgeon’s hand or the microscope’s focal point to the location of the imaged pathology, updated in “real time” in an “integrated operating room”, highlights. In its current form, Neuronavigation began in the 1990s and has adapted to new neuro-imaging technologies, real-time imaging capabilities, new technologies to transfer the information in the operating room for 3-D localization has greatly improved surgical outcomes and reduced theatre times and maximized the ability to excise the pathology  in most surgeriews. With neuro-navigation Neurosurgeon is able to visualize the scenario for surgery in a 3-D model of manipulable computer data. In this way the physician can “practice and check” the surgery, try alternative approaches, assess possible difficulties, etc., before the real surgery takes place.
