A brain filter for clear information transmission

Stefan Remy and colleagues at the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn have illuminated how this system works. "The system acts like a filter, only letting the most important impulses pass," explains Remy. "This produces the targeted neuronal patterns that are indispensible for long-term memory storage."

Family literacy project exceeds expectations

A unique approach to early literacy work with families where children develop their language skills and their ability to read and write from an early age has had a huge success.

Researchers from the University of Sheffield funded by the Economic and Social Research Council (ESRC) initially planned to use the approach with around 60 families, but discovered that around 6,000 had actually benefited from their work.

NFL players may be at higher risk of death from Alzheimer's and ALS

MINNEAPOLIS – New research shows that professional football players may be at a higher risk of death from diseases that damage the cells in the brain, such as Alzheimer's disease and ALS (also known as Lou Gehrig's disease), compared to the general U.S. population. The study is published in the September 5, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Study in mice suggests sleep problems may be early sign of Alzheimer's

Sleep disruptions may be among the earliest indicators of Alzheimer's disease, scientists at Washington University School of Medicine in St. Louis report Sept. 5 in Science Translational Medicine.

Working in a mouse model, the researchers found that when the first signs of Alzheimer's plaques appear in the brain, the normal sleep-wake cycle is significantly disrupted.

Gender equality influences how people choose their partners

Men and women clearly have different strategies for picking sexual partners, but the reason why differences exist is less clear. The classic explanation for these differences has been that men's and women's brains have evolved to make certain choices, but a new study in Psychological Science, a publication of the Association for Psychological Science, suggests that evolution is only part of the answer.

Teens tell different tales about themselves depending on gender

COLUMBIA, Mo. — During adolescence, the stories young people tell about themselves reflects their development of a personal identity and sense of self, and those autobiographical narratives vary depending on the teens' gender, according to a University of Missouri psychologist and her colleagues. Parents can use this knowledge of how teens talk about themselves to help understand the tumultuous transitions of their children into adults.

Scientists dramatically reduce plaque-forming substances in mice with Alzheimer's disease

COLUMBUS, Ohio – Scientists have found that eliminating an enzyme from mice with symptoms of Alzheimer's disease leads to a 90 percent reduction in the compounds responsible for formation of the plaques linked to Alzheimer's disease.

That is the most dramatic reduction in this compound reported to date in published research.

The compounds are amyloid beta, or A-beta peptides; peptides are proteins, but are shorter in length. When A-beta peptides accumulate in excessive amounts in the brain, they can form plaques, which are a hallmark of Alzheimer's disease.

Brainy beverage: Study reveals how green tea boosts brain cell production to aid memory

It has long been believed that drinking green tea is good for the memory. Now researchers have discovered how the chemical properties of China's favorite drink affect the generation of brain cells, providing benefits for memory and spatial learning. The research is published in Molecular Nutrition & Food Research.

That giant tarantula is terrifying, but I'll touch it

"Give sorrow words." —Malcolm in Shakespeare's "Macbeth"

Can simply describing your feelings at stressful times make you less afraid and less anxious?

A new UCLA psychology study suggests that labeling your emotions at the precise moment you are confronting what you fear can indeed have that effect.

The psychologists asked 88 people with a fear of spiders to approach a large, live tarantula in an open container outdoors. The participants were told to walk closer and closer to the spider and eventually touch it if they could.

Try a little tenderness and your brain will tell

Rio de Janeiro, Brazil- How would you respond if someone told you that you have a very dedicated son and that he got the scholarship he most wished? Or that the company you worked for made great profits and you will receive a good salary raise?

While the former situation represents a positive affiliative experience the latter is a non-affiliative one, and that, according to a paper published in tomorrow's issue of the Journal of Neuroscience, can make all the difference to the way your brain responds.

A blueprint for 'affective' aggression

A North Carolina State University researcher has created a roadmap to areas of the brain associated with affective aggression in mice. This roadmap may be the first step toward finding therapies for humans suffering from affective aggression disorders that lead to impulsive violent acts.

A*STAR scientists discover potential drug for deadly brain cancer

1. A*STAR scientists have identified a biomarker of the most lethal form of brain tumours in adults- glioblastoma multiforme. The scientists found that by targeting this biomarker and depleting it with a potential drug, they were able to prevent the progression and relapse of the brain tumour.

New neural pathway controlling skeletal development discovered

Jerusalem, Sept. 3, 2012 – Researchers at the Hebrew University of Jerusalem have discovered that a neuronal pathway -- part of the autonomic nervous system -- reaches the bones and participates in the control of bone development.

The eyes do have it: Men see things differently than women

The way that the visual centers of men and women's brains works is different, finds new research published in BioMed Central's open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.

Even in normal range, high blood sugar linked to brain shrinkage

MINNEAPOLIS – People whose blood sugar is on the high end of the normal range may be at greater risk of brain shrinkage that occurs with aging and diseases such as dementia, according to new research published in the September 4, 2012, print issue of Neurology®, the medical journal of the American Academy of Neurology.
