Why the brains GPS fails with age, and how some minds defy it

Stanford scientists found that aging disrupts the brains internal navigation system in mice, mirroring spatial memory decline in humans. Older mice struggled to recall familiar locations, while a few super-agers retained youthful brain patterns. Genetic clues suggest some animals, and people, may be naturally resistant to cognitive aging. The discovery could pave the way for preventing memory loss in old age.
