An Enzyme That Increases With Exercise Can Improve Memory In Mice, And Maybe People

By Richard Harris
Mice that exercise produce more of an enzyme that can improve memory and other brain functions.

When scientists revved up the production of an enzyme called GPLD1 in older mice, it stimulated nerve growth in their brains and the animals navigated a maze better.
