This observational study is looking at how well different brain mapping techniques can identify important brain functions (like speech or movement) in people with brain tumors. Researchers will use brain mapping (a diagnostic test that shows brain activity) before, during, and after surgery to see how these functions are affected by the tumor and its removal. The study aims to understand how the brain reorganizes itself after surgery. You may be able to join if you are 19 or older, have a primary or metastatic brain tumor in or near an "eloquent" brain region (an area responsible for important functions), and are able to participate in mapping procedures. The main goal is to measure your brain function one year after surgery.

Study design

This is an observational study planning to enroll 75 participants. It does not involve new treatments but rather observes how existing diagnostic tools work.

What's involved

You would undergo pre-operative evaluations including clinical exams, neuropsychological tests, MRI, fMRI, DTI, and MEG studies. During surgery, awake mapping will be performed. Post-surgery, you'll have routine follow-up, and repeat neuropsychological testing and mapping studies at 2 and 6 months.

Compensation

Not stated in the trial record.

Follow-up

Participants will be followed for at least one year, with brain function measured at that time.
