Understanding the degree of functional reserve in patient with brain tumor, when lesion is located in the eloquent cortex is important in presurgical evaluation to predict the surgical outcome as well reducing postoperative neurological deficits. For achieving this, a detailed knowledge of the functional topography and connectivity in whole brain level is crucial. In this study, our aim to understand the brain hyper and hypo connectivity in patients with high grade tumor who have deficits and who do not have deficits.
