Sentences with phrase «microglial activation»
Microglial activation refers to the process when a type of cells in the brain called microglia become active and start working harder. These cells are like the "clean-up crew" of the brain, and when they are activated, it means that they are trying to remove harmful substances or repair damaged tissues in the brain. Full definition
