This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are studying how the brain's natural cleaning system works—specifically, how fluid drains from inside the brain to lymph nodes in the neck. This study uses a harmless fluorescent dye called indocyanine green to track this drainage pathway in organ donors who have already decided to donate. Understanding this system better may help doctors improve how they care for the brain and protect it during medical procedures.
The brain has its own waste-removal system similar to a sewage network in a city, but scientists still don't fully understand how it works in people. By studying this natural drainage system, researchers hope to gain knowledge that could lead to better treatments and protection of the brain in future medical care.

This procedure takes place during the standard organ removal surgery. A small amount of fluorescent dye is injected into the fluid surrounding your brain, and a special camera tracks how it travels to the neck lymph nodes. Two small incisions are made and carefully closed for cosmetic appearance. The entire process is completed as part of the normal donation procedure, and all images are recorded for research analysis.
