The mission of neural stem cells located in the hippocampus, one of the main regions of the brain, is to generate new neurons during the adult life of mammals, and their function is to participate in certain types of learning and responses to anxiety and stress. New research has discovered that hippocampal neural stem cells in the case of epilepsy stop generating new neurons and are turned into reactive astrocytes, a cell type that promotes inflammation and alters communication between neurons. Now the researchers are exploring the potential of neural stem cells in future therapies to fight the disease.
