Young brain fluid improves memory in old mice

Cerebrospinal fluid (CSF) from young mice can improve memory function in older mice, researchers report today in Nature. A direct brain infusion of young CSF probably improves the conductivity of the neurons in ageing mice, which improves the process of making and recalling memories. The team also suggests that the improvements are largely due to a specific protein in the fluid.
“This is super exciting from the perspective of basic science, but also looking towards therapeutic applications,” says Maria Lehtinen, a neurobiologist at Boston Children’s Hospital in Massachusetts.
