Structural dynamics underlying memory in aging brains
(Medical Xpress)—When the brains of those who have succumbed to age-related neurodegeneration are analyzed post-mortem, they typically show significant atrophy on all scales. Not only is the cortex thinner ...

Neuroscientists show 'jumping genes' may contribute to aging-related brain defects
As the body ages, the physical effects are notable; wrinkles in the skin appear, physical exertion becomes harder. But there are also less visible processes going on. Inside aging brains there is another phenomenon at work, ...

New study refutes accepted model of memory formation
A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation—that it hinges on a single enzyme in the brain—is flawed. The new study, published in the Jan. 2 issue of Nature, found ...

Study identifies biological mechanism that plays key role in early-onset dementia
Using animal models, scientists at the Gladstone Institutes have discovered how a protein deficiency may be linked to frontotemporal dementia (FTD)—a form of early-onset dementia that is similar to Alzheimer's disease. ...
