This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This is a research study that observes how the brain's natural waste-removal system works. Using a harmless fluorescent dye called indocyanine green, researchers will track how fluid flows from inside the brain to lymph nodes in the neck. This research happens during organ donation procedures and helps scientists understand an important cleaning system in the brain that may be relevant to brain health.
The brain has its own system for removing waste and excess fluid, similar to how your body's lymph system works elsewhere. By studying this process carefully in organ donors, researchers hope to gain knowledge that could eventually help treat brain diseases or improve understanding of how the brain stays healthy.

This study takes place during the standard organ removal procedure. During surgery, doctors will make small incisions to inject a safe fluorescent dye into the space around the brain and observe how it travels to the neck lymph nodes using a special camera. The procedure adds minimal time to the donation process and includes careful closure of the incisions. All observations are recorded as images and videos for later analysis.
