Omega-3 levels affect whether B vitamins can slow brain's decline

While research has already established that B vitamin supplements can help slow mental decline in older people with memory problems, an international team have now found that having higher levels of Omega-3 fatty acids in your body could boost the B vitamins' effect.

Human sounds convey emotions clearer and faster than words

It takes just one-tenth of a second for our brains to begin to recognize emotions conveyed by vocalizations, according to researchers from McGill. It doesn't matter whether the non-verbal sounds are growls of anger, the laughter of happiness or cries of sadness. More importantly, the researchers have also discovered that we pay more attention when an emotion (such as happiness, sadness or anger) is expressed through vocalizations than we do when the same emotion is expressed in speech.

EMCDDA publishes report on antidote for heroin overdose

The first-ever substantive summary of research into take-home naloxone - a single injection that can be given by friends and family to revive someone suspected of heroin overdose - has been published today by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), in collaboration with researchers from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London.

New study gives squirrels plenty of food for thought

The age-old adage that 'practice makes perfect' has been found to illustrate how the humble grey squirrel solves problems in the search for food.

A new study by the University of Exeter has shown that persistence and the ability to choose the right behaviour to solve a problem are important aspects of problem solving in the common squirrel when they were learning to unravel challenges in the quest for nourishment.

Young whites at elite colleges see Asian-Americans as more competent than other minorities

Asian-Americans are stereotyped as "cold but competent" -- and more competent than blacks and Hispanics -- by young white students at elite colleges, according to a Baylor University study.

For decades, media have put forth Asian-Americans as a prime example of non-white people who are upwardly mobile because of characteristics that supposedly are less evident in other racial minorities, researchers say. They wanted to determine whether people commonly believe that.

New evidence in mice that cocaine makes brain cells cannibalize themselves

Working with mice, researchers at Johns Hopkins have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy, a process in which cells literally digest their own insides. Their results, moreover, bring with them a possible antidote, an experimental compound dubbed CGP3466B.

Tiny electronic implants monitor brain injury, then melt away

CHAMPAIGN, Ill. -- A new class of small, thin electronic sensors can monitor temperature and pressure within the skull - crucial health parameters after a brain injury or surgery - then melt away when they are no longer needed, eliminating the need for additional surgery to remove the monitors and reducing the risk of infection and hemorrhage.

Team develops wireless, dissolvable sensors to monitor brain

A team of neurosurgeons and engineers has developed wireless brain sensors that monitor intracranial pressure and temperature and then are absorbed by the body, negating the need for surgery to remove the devices.

Thwarting abnormal neural development with a new mutation

Researchers at the RIKEN Brain Science Institute in Japan have discovered how to reverse the abnormal axonal development characteristic of CFEOM3, a congenital disease that affects the muscles that control eye movements. Published in Nature Communications, the work shows how creating a specific mutation rescued abnormal axonal growth in the developing mouse brain.

Poverty linked to childhood depression, changes in brain connectivity

Many negative consequences are linked to growing up poor, and researchers at Washington University St. Louis have identified one more: altered brain connectivity.

Simulator-based training in veterinary medicine

Simulator-based training of students at Vetmeduni Vienna has been part of the curriculum since 2012. The Skills Lab is a simulated veterinary practice in which students have the chance to train a variety of veterinary interventions in a near-realistic setup on animal dummies.

Mentally challenging activities key to a healthy aging mind

One of the greatest challenges associated with the growing numbers of aged adults is how to maintain a healthy aging mind. Taking up a new mental challenge such as digital photography or quilting may help maintain cognitive vitality, say researchers reporting in Restorative Neurology and Neuroscience.

Recent evidence suggests that engaging in enjoyable and enriching lifestyle activities may be associated with maintaining cognitive vitality. However, the underlying mechanism accounting for cognitive enhancement effects have been poorly understood.

UCLA psychology study explains when and why bystanders intervene in cyberbullying

People on social media are often unsupportive of cyberbullying victims who have shared highly personal feelings, UCLA psychologists report.

Compared to face-to-face situations, bystanders are even less likely to intervene with online bullying. The researchers wanted to learn why bystanders are infrequently supportive of when bullying occurs online.

Autism-linked protein lays groundwork for healthy brain

LA JOLLA--A gene linked to mental disorders helps lays the foundation for a crucial brain structure during prenatal development, according to Salk Institute research published January 14, 2016 in Cell Reports.

The findings reveal new mechanistic insights into the gene, known as MDGA1, which may bring a better understanding of neurodevelopmental disorders in people, says Carlos Perez-Garcia, the study's lead author and a staff researcher in the laboratory of Professor Dennis O'Leary, holder of the Vincent J. Coates Chair in Molecular Neurobiology.

Poor sleep in seniors linked to hardened brain arteries

DALLAS, Jan. 14, 2016 -- Poor sleep quality in elderly persons is associated with more severe arteriosclerosis in the brain as well as a greater burden of oxygen-starved tissue (infarcts) in the brain - both of which can contribute to the risk of stroke and cognitive impairment. The findings are reported in the American Heart Association's journal Stroke.
