The brain has a critical window for language development between the ages of two and four, brain scans suggest.
Environmental influences have their biggest impact before the age of four, as the brain’s wiring develops to process new words, say UK and US scientists.
The research in The Journal of Neuroscience suggests disorders causing language delay should be tackled early.
It also explains why young children are good at learning two languages.

Brain scientists have discovered that swerving around cars while simultaneously picking out road signs in a video game can improve the short-term memory and long-term focus of older adults. Some people as old as 80, the researchers say, begin to show neurological patterns of people in their 20s.
Cognitive scientists say the findings, to be published Thursday in the scientific journal Nature, are a significant development in understanding how to strengthen older brains. That is because the improvements in brain performance did not come just within the game but were shown outside the game in other cognitive tasks.

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.
Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco’s finger to move on a keyboard.

Dyslexia is a common learning disorder that affects around 1 in 10 people in the U.S., where it is typically diagnosed around second grade but sometimes goes undiagnosed and unmanaged well into adulthood. And though it is technically a learning disorder, it actually occurs in people with normal vision and intelligence, according to the Mayo Clinic.
Now researchers at the Massachusetts Institute of Technology and Boston Children’s Hospital say that a type of MRI scan called diffusion-weighted imaging could help diagnose the disorder in kids before they even start to learn to read — a discovery that could help teachers and experts intervene early to manage it.

The more time you spend on cerebral activities, the better prepared your brain is to withstand the ravages of age.
That’s the takeaway from research just published in the journal Neurology that confirms—and helps explain why—people who habitually read, write, and otherwise process information are less likely to experience mental declines late in life.
The study suggests that while a mentally active lifestyle may not prevent formation of the plaques and tangles associated with Alzheimer’s disease, it makes it less likely their presence will impair one’s mental functioning.

The absent-minded professor is a classic image: someone who’s lost in deep thoughts all the time but pays very little attention to the what’s going on right in front of them. Well, there may be a little something to that cliché (if only just a little) if a study published this week in Current Biology is to be believed. The study showed that IQ scores, an imperfect measure of people’s general mental faculties, correlated with their tendency to ignore an image that may be mistaken for background visual noise.
