Medical Xpress: Unlocking the potential of stem cells to repair brain damage

QUT scientist is hoping to unlock the potential of stem cells as a way of repairing neural damage to the brain. Rachel Okolicsanyi, from the Genomics Research Centre at QUT’s Institute of Health and Biomedical Innovation, said unlike other cells in the body which were able to divide and replicate, once most types of brain cells died, […]

News-Medical: Brain circuitry rescues tongue while chewing

Eating, like breathing and sleeping, seems to be a rather basic biological task. Yet chewing requires a complex interplay between the tongue and jaw, with the tongue positioning food between the teeth and then moving out of the way every time the jaw clamps down to grind it up. If the act weren’t coordinated precisely, […]

Popular Mechanics: Study: Electrical Signals Can Regrow Brain Cells

Scientists have found a kind of brain cell in mice that can instruct stem cells to start making more neurons, according to a new study. In addition, they found that electrical signals could trigger this growth in rodents, raising the intriguing possibility that devices could one day help the human brain repair itself. The study appears […]

Science News: Stress and the susceptible brain

We all respond to stress in different ways. Some of us work harder. Others drink more or eat our feelings. Sometimes we experience sleep loss, heart palpitations or sweats. When the stress dissipates, many of us go back to our daily lives, none the worse for wear. We are resilient. But some people find that […]

Health Canal: Brain signals link physical fitness to better language skills in children

Children who are physically fit have faster and more robust neuro-electrical brain responses during reading than their less-fit peers, researchers report. These differences correspond with better language skills in the children who are more fit, and occur whether they’re reading straightforward sentences or sentences that contain errors of grammar or syntax. The new findings, reported […]

BBC: Learning second language ‘slows brain ageing’

Learning a second language can have a positive effect on the brain, even if it is taken up in adulthood, a University of Edinburgh study suggests. Researchers found that reading, verbal fluency and intelligence were improved in a study of 262 people tested either aged 11 or in their seventies. A previous study suggested that […]

LA Times: Learning a second language at any age may slow the brain’s decline

Bilingual education in schools has long been a political hot potato — it was banned in California by a 1998 ballot measure, which the state Senate is now asking voters to repeal. But politics aside, there’s an increasing amount of scientific support for the benefits of knowing (at least) two languages. Now, a new study […]

The Guardian: Dementia Treatment Depends on Cause

Before Alzheimer’s Disease became a household word, the combination of forgetfulness and agitation were typically categorized under the catch-all terms dementia, senior dementia or senility. Today, it is Alzheimer’s that has become the catchall despite the fact that dementia is caused by many diseases and proper treatment depends on identifying the cause. Doctors use the […]

International Business Times: Mind Games Push Athletes Beyond Their Limits

New research shows athletes can be tricked into beating their personal best if they are told they are performing worse than they are. The technique helps athletes overcome an artificial performance limit set by the brain, which normally protects the body from exhaustion and injury. It was tested on 14 competitive male cyclists who took part in […]
