Evidence for potentials and limitations of brain plasticity using an atlas of functional resectability of WHO grade II gliomas: Towards a “minimal common brain”

►Resectability of brain areas is unpredictable before tumor surgery due to reshaping. ►Electrical mapping allows the study of potentials and limitations of plasticity. ►We build an atlas of functional resectability based on postoperative residue. ►Each voxel represents the probability to observe non-compensable area. ►Our atlas highlights the existence of a “minimal common brain” among patients.
