Since the advent of modern neurosurgery, localization of lesions, electrophysiological study of brain, functional mapping, and awake craniotomy have been practiced and later developed by the stalwarts and pioneers of neurosurgery such as Penfield and Cushing before MRI stepped in into clinical practice.
After the introduction of MRI, new modalities facilitated the procedure of surgical planning to achieve the microsurgical goal and improve prognosis and quality of life in patients. Despite variable applications of preoperative and intraoperative mapping and monitoring systems, several limitations and concerns are reported for every modality as well.
In this issue of the IrJNS, we are delighted to present valuable papers discussing different aspects of brain mapping in neurosurgical oncology. Original papers and reviews exploring this exciting field are encouraged for peer-review.
