Brain electrode recordings during awake surgery could sharpen tumor removal
NCT ID NCT05875935
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study investigates whether recording brain electrical activity during awake surgery can help identify networks involved in thinking and language. In people with glial brain tumors located in critical functional areas, surgeons place electrode grids on the brain before waking the patient. By correlating these recordings with imaging data, researchers aim to map tumor and healthy tissue more precisely. The goal is to remove more of the tumor while reducing the risk of long-term neurological damage.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- electrocorticography (ECoG) recording during awake surgery
- What this could lead to
- If successful, this approach could help surgeons remove brain tumors more completely while preserving cognitive functions, potentially improving survival and quality of life.
- What could go wrong
- This is a very small, early-stage study with only one participant, so results may not apply broadly. The technique is complex and may not translate into routine practice.
