Your brain has its own built-in cleaning crew, and the process is called phagocytosis. Specialized brain cells—mainly microglia—constantly patrol your grey matter, identifying and removing old, dead, or damaged cells.

This cellular “cleanup” keeps your brain healthy, prevents inflammation, and ensures your neural networks stay sharp.
It might sound creepy, but it’s one of the most essential housekeeping jobs your brain performs every day!
