Copper on the brain at rest

ons, 11/26/2014 - 18:44
Proper copper levels are essential to the health of the brain at rest, new research shows. The brain consumes 20-percent of the oxygen taken in through respiration. This high demand for oxygen and oxidative metabolism has resulted in the brain harboring the body's highest levels of copper, as well as iron and zinc. Over the past few years, researchers have developed a series of fluorescent probes for molecular imaging of copper in the brain.

An enzyme that fixes broken DNA sometimes destroys it instead, researchers find

ons, 11/26/2014 - 18:43
Enzymes inside cells that normally repair damaged DNA sometimes wreck it instead, researchers have found. The insight could lead to a better understanding of the causes of some types of cancer and neurodegenerative disease.

Dogs hear our words and how we say them

ons, 11/26/2014 - 18:43
When people hear another person talking to them, they respond not only to what is being said -- those consonants and vowels strung together into words and sentences -- but also to other features of that speech -- the emotional tone and the speaker's gender, for instance. Now, a report provides some of the first evidence of how dogs also differentiate and process those various components of human speech.

Elderly brains learn, but maybe too much

ons, 11/26/2014 - 18:43
Learning requires both mental flexibility, or 'plasticity,' and stability. A new study finds that in learning a visual task, older people exhibited a surprising degree of plasticity, but had trouble filtering out irrelevant information, suggesting that their learning was not as stable.

Cognitive test battery developed to assess impact of long duration spaceflights on astronauts' brain function

ons, 11/26/2014 - 18:39
A cognitive test battery, known as Cognition, has been developed for the National Space Biomedical Research Institute (NSBRI) to measure the impact of typical spaceflight stressors (like microgravity, radiation, confinement and isolation, exposure to elevated levels of CO2, and sleep loss) on cognitive performance. This computer-based test has already been tested by astronauts on Earth. It will be performed for the first time in a pilot study on the International Space Station (ISS) on November 28.

Isolation of important centres in brain results in age-related memory deficits

ons, 11/26/2014 - 15:41
Poor memory among the elderly can be explained by regions in the hippocampus complex, an important part of the brain, becoming more co-active during rest, thereby interacting less efficiently with other parts of the brain when we try to memorize information, researchers report.

Pleasure at another's misfortune is evident in children as young as two

ons, 11/26/2014 - 15:40
Even very young children will show signs of schadenfreude when an inequitable situation is rectified. Until now, researchers believed that children didn't develop such a sophisticated emotion until the age of seven, but a new study found evidence of schadenfreude in children as young as two.

How various brain areas interact in decisions

ons, 11/26/2014 - 13:53
Our decisions can be pictured in the brain, and now scientists have been able to show in a recent study which areas are most active in decision making. Often the so-called prefrontal cortex not only apparently shows increased activity during decisions that require self-control, but in general during decision making. The results could be of use in promoting decision skills in difficult decisions.

Despite a sequence of stellar performances by Britain’s female athletes and team game players, coverage of women’s sport in the Press still occupies a fraction of the space given to men, according to an expert who has analyzed thousands of articles in newspapers that she describes as a “football-saturated boyzone”.

Why do people with autism see faces differently?

ons, 11/26/2014 - 13:51
The way people with autism spectrum disorder (ASD) gather information – not the judgement process itself – might explain why they gain different perceptions from peoples’ faces, according to a new study. "The evaluation of an individual's face is a rapid process that influences our future relationship with the individual," said the lead author of the study. "By studying these judgments, we wanted to better understand how people with ASD use facial features as cues. Do they need more cues to be able to make the same judgment?"

Diagnosing deafness early will help teenagers' reading development

ons, 11/26/2014 - 02:57
Deaf teenagers have better reading skills if they were identified as deaf by the time they were nine months old, research has shown. The research team has been studying the development of a group of children who were identified with permanent childhood hearing impairment (PCHI) at a very early age. Follow up assessments when the children were aged eight showed those who were screened at birth had better language skills than those children who were not screened.

Mere expectation of treatment can improve brain activity in Parkinson's patients

tir, 11/25/2014 - 20:08
Learning-related brain activity in Parkinson's patients improves as much in response to a placebo treatment as to real medication, according to a new study. "The findings highlight the power of expectations to drive changes in the brain," said a co-author of the study. "The research highlights important links between psychology and medicine."
