The purpose of this study is to determine if functional MRI is precise enough to provide
information about the location of brain functions in patients who have brain tumors. This
might allow physicians to use a non-invasive procedure to assist with brain mapping prior to
The purpose of this study is to determine if fMRI is precise enough to be used in
preoperative decision making for patients who have brain tumors. Before a patient has brain
surgery to have the tumor removed, functional mapping of the brain takes place either
intra-operatively or post operatively after a subdural grid implant has been placed. Mapping
helps the surgeon determine which areas of the brain are responsible for different important
body functions. During this mapping procedure the surgeon determines if they can safely
remove all or part of a brain tumor. The investigators are hoping to show that fMRI is just
as accurate in mapping out different areas of the brain, without having to utilize an
invasive form of brain mapping.
