Brain reorganizes to make room for math
sea-maid submitted, created time 1 week 2 days (www.sciencenews.org)
It takes years for children to master the ins and outs of arithmetic. New research indicates that this learning process triggers a large-scale reorganization of brain processes involved in understanding written symbols for various quantities.
According to this article, when adults work on math problems, they show activity in a part of the brain known to be associated with linking written symbols to the things they represent, like numerical values, words, and musical notes 
Sharp-witted elderly shed insight on dementia

People who manage to keep a razor-sharp memory well into their 80s appear to have fewer fiber-like tangles of a protein linked with Alzheimer's than those who age normally, U.S. researchers said on Sunday.

When it comes to the neurobiology of memory, the hippocampus typically gets most of the credit. But although this brain region is crucial for recording new memories, like the name of someone you just met at a bar, people with a damaged hippocampus can still recall memories from days of old. Many neuroscientists believe this is because lasting memories get shifted to the cerebral cortex for permanent storage. Little is known about how this might happen, but a study in today's issue of Science provides some clues.
Molecular Motor Tied to Memory

How does the brain record a memory? Somehow our experiences and interactions can be imprinted in the mind, but exactly how neurons alter their connections to enable memory has been murky. Now a team of researchers out of Duke University say they have identified the molecular machinery that links experience with learning--and it all comes down to one microscopic motor.
Eating fatty fish lowers risk of dementia

Eating tuna and other fatty fish may help prevent memory loss in addition to reducing the risk of stroke, Finnish researchers said on Monday.
First-ever trial proves exercise helps memory

West Australian health experts are urging older people to get active after proving for the first time that just twenty minutes of activity each day can prevent memory deterioration. In a world-first, a team from the WA Centre for Health and Ageing (WACHA) based at the Western Australian Institute for Medical Research (WAIMR) has shown that regular physical activity can lead to a lasting improvement in memory function.

A new study has found that older rats seem to replay previous events less and, as a result, have more trouble remembering than younger animals.
Could those memory problems be due to a decline in the brain's replay during sleep? How can these results be extrapolated to humans?
Thanks for the future memories
sea-maid submitted, created time 4 months 2 weeks (www.sciencenews.org)
Scientists have found that the same machinery that we use to construct our memories of the past also helps us to imagine and envision the future.
Other studies show that total amnesiacs report a “blank” when asked about their personal futures. And severely depressed patients, who tend to think about both the past and future in a nonspecific manner, have difficulty visualizing positive future events.
This article also discusses different kinds of memories, how they're constructed, and how they might contribute to an individual's life and survival.
Sleep loss produces false memories

Sleepless nights can increase your chances of forming false memories, according to researchers in Germany and Switzerland. But, as for so many aspects of life, it seems that coffee can save the day.
Memories of your last meal can help you stay thin

Perhaps it really is possible to think yourself slimmer. Concentrating on a recent meal turns out to significantly reduce the desire to snack, suggesting that certain ways of thinking can curb your appetite.
Blocking appetite could block other things as well
Darkfrog submitted, created time 6 months 3 weeks (www.nature.com)
A stomach hormone called ghrelin has been identified as a stimulant of the pleasure-causing portions of the brain. That's what makes all that food seem so extra appealing when one walks into a grocery store while hungry. What's new to this matter is the ability ghrelin has to stimulate and improve memories--at least memories of food.
Suppressing ghrelin has been proposed as a means of treating obesity, but this study suggests that doing so might have unpleasant mental side effects for those treated
Dementia Study-- Brain size may protect Alzheimer's patients from memory loss

Having a large hippocampus - a part of the brain involved with memory - seems to provide protection against the symptoms of dementia, a study suggests.
Gingko Biloba, Memory Study Brings Surprises
Sue Wu submitted, created time 9 months 3 days (medheadlines.com)
In the first ever randomized controlled trial of gingko biloba and memory using only participants age 85 and older, improved memory is questionable but another finding is even more surprising. While the participants in the ginkgo group showed only mild memory improvement in only one area, they also showed a significantly higher risk of mini-stroke, not surprising considering that gingko increases the flow of blood to the brain.
Is Old Age Memory Decline Reversible?

Scientists have found that a lessened supply of new nerve cells in the adult brain apparently triggers short-term memory loss typically associated with aging, setting the stage for one day developing therapies designed to maintain a steady supply of fresh neurons to keep the mind sharp.

Memory-prompting abilities of brain stimulation discovered by accident. Electrodes implanted into the brain of a patient undergoing an experimental treatment for obesity have surprisingly improved his memory skills. It will suppress appetite too.
