Professor von Zglinicki, professor of Cellular Gerontology at Newcastle University said: "We will now need to find out whether the same mechanisms we detected in mouse brains are also associated with brain ageing and cognitive loss in humans. We might have opened up a short-cut towards understa...
The gene, Bdnf, encodes a protein that helps neurons in cognitive centres of the brain to form connections called synapses. Cui-Wei Xie and her colleagues at the University of California, Los Angeles, analysed brain slices from young, middle-aged and aged rats. Aged rat brains showed a decre...
As brains change over time, there are measurable results that affect a person's cognition. Explore some of the changes that occur to a person's brain as they age, including changes in attention and memory, and discover the relationship between aging, cognition, and brain changes. ...
Sixty women had their first 3T MRI scan around the age of 59, of which 40 completed follow-up cognitive assessments over a decade. Of the 40, 23 had follow-up MRI scans. The follow-up scans indicated that in addition to the expected age-related atrophy rate (breakdown of brain tissue),...
Dthe rats'brains expanded or shrank depending on the level of mental activity 3. A comparison between adults and children who played chess showed that Athe children were as capable as the adults of remembering a series of numbers Bthe children had better recall of the layout of pieces ...
Images acquired from the brains of these ex-athletesreveal microscopic structural injuries that are thought to interfere with the ability of different regions of the brain to communicate with each other, leading to poor cognitive performance. In short, if you’re looking for a team sport that’s...

Storing information is an important function of our brains and scientists are always looking at ways to improve it but also to stop it deteriorating – or becoming worse. Rob Yes, and we all know that memories –that's the noun word for things we remember from the past – are nice to...
