How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
No phase is given. This study only records brain activity during surgery.
Status: Recruiting. It is looking for patients now. Talk to your care team about whether it fits you.

The short version
This study listens to how brain cells fire next to a brain tumor during surgery.
Who this trial is for. This study is for people having surgery for a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary, a kind of brain tumor. During the surgery, the team uses small electrodes to record how single brain cells fire in the brain next to the tumor.
Where it stands. The study has not reported results. It is measuring how brain cells fire in the area around the tumor. The team wants to map how a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary changes that activity. The answer is not in yet.
What this means, and what it doesn't
What it could mean: Nothing here changes your care today. The goal is to understand how a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary changes nearby brain activity. The team hopes that helps future work on seizures and tumor growth. Someone having glioma surgery could ask their care team about it.
What it doesn't mean: This does not mean a new treatment has been shown to work. A trial is a test, not proven care. Taking part is not a promise that it will help you. It is not a cure.
