Testing New Flexible Brain Electrodes During Brain Tumor Surgery

This is the first human study of a brand new type of electrode called a graphene micro-electrocorticography array. These electrodes are much thinner and more flexible than standard brain electrodes and use a special carbon material that can detect electrical brain signals more sensitively. If you join this study, surgeons would use these new electrodes during your planned brain tumor removal surgery to map which areas of your brain control important functions like movement and speech.

Current brain electrodes have limits — they don't bend well to fit the brain's shape, need to be quite large to pick up signals, and can't always be placed where they're needed most. This trial exists to test whether the new graphene electrodes solve these problems, potentially giving surgeons better information to protect critical brain areas during your operation.
