Scientists Test Whether Brain Stimulation Could Help Sharpen Aging Memory

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.
