Higher Education Keeps Late-Life Memory Strong

Now, a new study gives clues as to how higher education buffers people from age-related declines in intellect.

Researchers from the University of Toronto found that added years of education are associated with increased activity in the brain's frontal lobes.

The study suggests the frontal cortex is engaged by older adults -- especially those who are highly educated -- as an alternative network that may aid memory and other intellectual tasks as they age.
