Mobile tech and talk therapies strike at the moment binge eating urges do

PHILADELPHIA (September 27, 2013) -- Two new treatment methods under investigation at Drexel University aim to help people reduce binge-eating behavior.

A smartphone app in development will track users' individual patterns of eating and binge eating behavior and alert them at times when they are at risk for binge behaviors, among a comprehensive suite of other features.

Ballet dancers' brains adapt to stop them getting in a spin

Scientists have discovered differences in the brain structure of ballet dancers that may help them avoid feeling dizzy when they perform pirouettes.

The research suggests that years of training can enable dancers to suppress signals from the balance organs in the inner ear.

The findings, published in the journal Cerebral Cortex, could help to improve treatment for patients with chronic dizziness. Around one in four people experience this condition at some time in their lives.

Findings: How viral infection disrupts neural development in offspring, increasing risk of autism

(SACRAMENTO, Calif.) — Activating a mother's immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology have found. They said the finding suggests how maternal viral infection might increase the risk of having a child with autism spectrum disorder or schizophrenia.

UNC scientists identify brain circuitry that triggers overeating

CHAPEL HILL, N.C. -- Sixty years ago scientists could electrically stimulate a region of a mouse's brain causing the mouse to eat, whether hungry or not. Now researchers from UNC School of Medicine have pinpointed the precise cellular connections responsible for triggering that behavior. The finding, published September 27 in the journal Science, lends insight into a cause for obesity and could lead to treatments for anorexia, bulimia nervosa, and binge eating disorder -- the most prevalent eating disorder in the United States.

Patient's own cells might be used as treatment for Parkinson's disease

Induced pluripotent stem cells (iPSCs) taken from a patient hold great therapeutic potential for many diseases. However, studies in rodents have suggested that the body may mount an immune response and destroy cells derived from iPSCs. New research in monkeys refutes these findings, suggesting that in primates like us, such cells will not be rejected by the immune system.

Newly identified antibodies effectively treat Alzheimer's-like disease in mice

Alzheimer's disease is characterized by the accumulation of particular toxic proteins in the brain that are believed to underlie the cognitive decline in patients. A new study conducted in mice suggests that newly identified antibody treatments can prevent the accumulation of one of these of these toxic components, called tau proteins. The findings, online September 26 in the Cell Press journal Neuron, suggest that these antibodies may provide a basis for a promising therapy for patients with Alzheimer's disease and other neurodegenerative disorders.

Autologous transplantation shows promising results for iPS cell therapy in Parkinson's disease

A research team led by Professor Jun Takahashi and Assistant Professor Asuka Morizane at the Center for iPS Cell Research and Application (CiRA) at Kyoto University, Japan, has carried out a study to compare the impact of immune response in autologous transplantation (transplantation of cells from the subject's own body) and allogeneic transplantation (transplantation of cells from a different individual of the same species). The researchers used cynomolgus monkeys to carry out transplantation into the brain of neural cells derived from iPS cells.

Bone hormone influences brain development and cognition

NEW YORK, NY (September 26, 2013) — Researchers from Columbia University Medical Center (CUMC) have found that the skeleton, acting through the bone-derived hormone osteocalcin, exerts a powerful influence on prenatal brain development and cognitive functions such as learning, memory, anxiety, and depression in adult mice. Findings from the mouse study could lead to new approaches to the prevention and treatment of neurologic disorders. The study was published today in the online edition of Cell.

Colonizing songbirds lost sense of syntax

DURHAM, N.C. -- As one species of European songbird island-hopped to colonize mid-Atlantic archipelagoes over the course of a half million years, their songs lost their sense of syntax.

Chaffinches (Fringilla coelebs) on the furthest island of their dispersal, Gran Canaria in the Canary Islands, still sing the same notes, but with a much less structured pattern from one bird to the next, sort of like an island of Charlie Parkers.

Penn researchers use Facebook data to predict users' age, gender and personality traits

In the age of social media, people's inner lives are increasingly recorded through the language they use online. With this in mind, an interdisciplinary group of University of Pennsylvania researchers is interested in whether a computational analysis of this language can provide as much, or more, insight into their personalities as traditional methods used by psychologists, such as self-reported surveys and questionnaires.

Can traumatic brain injury impair a child's working memory?

New Rochelle, NY, September 26, 2013—Traumatic brain injury (TBI) during childhood can have long-term effects on cognitive and psychosocial functioning, including poor academic achievement. Pediatric TBI can cause significant deficits in working memory, as demonstrated in a study published in Journal of Neurotrauma, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Neurotrauma website at http://www.liebertpub.com/neu.

Lithium in the brain

This news release is available in German.

At present lithium is most popular for its use in rechargeable batteries. But for decades now, lithium has also been used to treat various psychological diseases such as depressions, manias and bipolar disorders. But, the exact biological mode of action in certain brain regions has hardly been understood. It is well known that lithium lightens moods and reduces aggression potential.

An analgesic molecule discovered in its natural state in Africa

Even more surprising, analysis show that the molecule is identical to Tramadol, a wholly synthetic medication that is used world-wide as a painkiller. According to the research team, this is the first time ever that a synthetic medication produced by the pharmaceutical industry has been discovered in strong concentrations in a natural source. This unexpected discovery had just been published in the chemical journal' "Angewandte Chemie"

Debt linked to mental health problems

New research, led by the University of Southampton, has shown that people in debt are three times more likely to have a mental health problem than those not in debt.

There is currently around £156 billion in unsecured debt such as credit cards in the UK, of which the average family owes more than £11,000. Levels of debt have increased in recent years due to the economic recession and are predicted to increase further.
