Creating inclusive child-care spaces

(Edmonton) Researchers from the University of Alberta are teaming up with child-care providers and day-home operators to ensure they have adequate training and support needed to offer inclusive spaces for children with disabilities.

Lesley Wiart was the lead author of a new study that identified challenges in providing inclusive spaces for children with physical disabilities, cognitive impairments and behavioural issues. The research showed that many Alberta child-care centres and day homes support inclusion but sometimes lack training and support.

Brain scans might predict future criminal behavior

ALBUQUERQUE, NM and DURHAM, NC--A new study conducted by The Mind Research Network in Albuquerque, N.M., shows that neuroimaging data can predict the likelihood of whether a criminal will reoffend following release from prison.

The paper, which is to be published in the Proceedings of the National Academy of Sciences, studied impulsive and antisocial behavior and centered on the anterior cingulate cortex (ACC), a portion of the brain that deals with regulating behavior and impulsivity.

Surgical menopause may prime brain for stroke, Alzheimer's

Women who abruptly and prematurely lose estrogen from surgical menopause have a two-fold increase in cognitive decline and dementia.

"This is what the clinical studies indicate and our animal studies looking at the underlying mechanisms back this up," said Brann, corresponding author of the study in the journal Brain. "We wanted to find out why that is occurring. We suspect it's due to the premature loss of estrogen."

Scientists identify brain's 'molecular memory switch'

Scientists have identified a key molecule responsible for triggering the chemical processes in our brain linked to our formation of memories. The findings, published in the journal Frontiers in Neural Circuits, reveal a new target for therapeutic interventions to reverse the devastating effects of memory loss.

The BBSRC-funded research, led by scientists at the University of Bristol, aimed to better understand the mechanisms that enable us to form memories by studying the molecular changes in the hippocampus — the part of the brain involved in learning.

Marital conflict causes stress in children, may affect cognitive development

Marital conflict is a significant source of environmental stress for children, and witnessing such conflict may harm children's stress response systems which, in turn, may affect their mental and intellectual development.

These conclusions come from a new study by researchers at Auburn University and the Catholic University of America. The study appears in the journal Child Development.

Boston Public Schools' prekindergarten program boosts children's skills

Boston Public Schools' prekindergarten program is substantially improving children's readiness to start kindergarten, according to a new study of more than 2,000 children enrolled there. The program uses research-based curricula and coaching of teachers, is taught primarily by masters-level teachers, and is open to any child regardless of family income.

Seeing happiness in ambiguous facial expressions reduces aggressive behavior

Encouraging young people at high-risk of criminal offending and delinquency to see happiness rather than anger in facial expressions results in a decrease in their levels of anger and aggression, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.

Pinning down the pain

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, says a key protein in Schwann cells performs a critical, perhaps overarching, role in regulating the recovery of peripheral nerves after injury. The discovery has implications for improving the treatment of neuropathic pain, a complex and largely mysterious form of chronic pain that afflicts over 100 million Americans.

The findings are published in the March 27, 2013 issue of the Journal of Neuroscience.

Pesticide combination affects bees' ability to learn

Two new studies have highlighted a negative impact on bees' ability to learn following exposure to a combination of pesticides commonly used in agriculture. The researchers found that the pesticides, used in the research at levels shown to occur in the wild, could interfere with the learning circuits in the bee's brain. They also found that bees exposed to combined pesticides were slower to learn or completely forgot important associations between floral scent and food rewards.

Researchers discover primary role of the olivocochlear efferent system

New research from the Massachusetts Eye and Ear, Harvard Medical School and Harvard Program in Speech and Hearing Bioscience and Technology may have discovered a key piece in the puzzle of how hearing works by identifying the role of the olivocochlear efferent system in protecting ears from hearing loss. The findings could eventually lead to screening tests to determine who is most susceptible to hearing loss. Their paper is published today in the Journal of Neuroscience.

Environmental enrichment important factor impacting cell transplantation and brain repair

Putnam Valley, NY. (March. 27, 2013) – A team of Korean researchers investigated whether "environmental enrichment" can improve the neurobehavioral function of six week-old mice after transplantation of adipose-derived stem cells (ASCs) to treat hypoxic-ischemic brain injury, and found that brain repair (neurogenesis) was aided in some animals through exercise-induced fibroblast growth factor 2 (FGF2), a strong pro-angiogenic factor.

The post-transplantation environmental enrichment (EE) included use of a running wheel and exposure to "novel objects."

Virtual games help the blind navigate unknown territory

On March 27thJoVE (Journal of Visualized Experiments) will publish a new video article by Dr. Lotfi Merabet showing how researchers in the Department of Ophthalmology at Massachusetts Eye and Ear Infirmary and Harvard Medical School have developed a virtual gaming environment to help blind individuals improve navigation skills and develop a cognitive spatial map of unfamiliar buildings and public locations.

Human emotion: We report our feelings in 3-D

Philadelphia, PA, March 26, 2013 – Like it or not and despite the surrounding debate of its merits, 3-D is the technology du jour for movie-making in Hollywood. It now turns out that even our brains use 3 dimensions to communicate emotions.

Paranoia persists in mugging victims for months after attack, study finds

Being mugged or randomly attacked in the street often leaves people paranoid and distrustful of others long after the attack, according to a study published today. The research highlights a previously under-recognised consequence of physical assault which will help to inform therapy for those seeking help.

Mice show innate ability to vocalize

VANCOUVER, Wash.—Scientists have long thought that mice might serve as a model for how humans learn to vocalize. But new research led by scientists at Washington State University-Vancouver has found that, unlike humans and songbirds, mice do not learn how to vocalize.

But the results, published in the current Journal of Neuroscience, point the way to a more finely focused, genetic tool for teasing out the mysteries of speech and its disorders.
