This novel study sheds light on the subset of microglia, the brain’s immune cells, and the role they play in cognition & memory — Brain immune cells, also known as microglia, have multifaceted functions in the central nervous system (CNS). Their primary role is immune surveillance, continuously monitoring the brain environment for signs of infection, injury, or abnormalities. When activated, microglia play a vital role in the inflammatory response, releasing chemical signals and pro-inflammatory…
