Scientists Test Whether Brain Stimulation Could Help Sharpen Aging Memory
BY JONATHAN LAMBERT
It’s an unfortunate fact of life — as we age, we tend to become more forgetful.
Aging brains struggle especially with working memory. Called the workbench of the mind, working memory allows us to store useful bits of information for a few seconds, and use that information across different brain areas to help solve problems, plan, or make decisions.
Researchers are trying to understand why this ability fades as we age, and whether we can slow, or reverse, that decline.
One leading hypothesis contends that working memory works by far-flung brain areas firing synchronously. When two areas are on the same brain wavelength, communication is tight, and working memory functions seamlessly.
But as we age, these brain areas start falling out of step, and these once tightly linked brain areas are no longer on the same page. A study published Monday in Nature Neuroscience demonstrates a link between these mismatched brain rhythms and declines in working memory in older adults and shows that a precise form of electrical stimulation applied to the scalp can coax these brain areas back into sync.
In late autumn on the cusp of cool winter days, snow comes early to Washington when thousands of aloft avians, snow geese, land here in a flurry of white feathers.
“We call it a snow storm, they just will move as one,” said birder Julie Hagen. “It’s just this chaotic whirlwind of birds, they move like a cloud and then they just lift up in the air.”
