Uninterrupted Playtime between Siblings Is Key for Learning

Full article at

Whether it’s how to throw a ball or put together a puzzle, young children learn a lot from their older siblings. While researchers have long known that brothers and sisters teach each other about the world, most of their observations about this have been made in a lab setting.

The research is in Journal of Cognition and Development. (full access paywall)

Research: “This Bird Can’t Do It ’cause this Bird Doesn’t Swim in Water: Sibling Teaching during Naturalistic Home Observations in Early Childhood” by Nina Howe, Sandra Della Porta, Holly Recchia, Allyson Funamoto and Hildy Ross in Journal of Cognition and Development. doi:10.1080/15248372.2013.848869

Image: The children were encouraged to play together, but not given particular instructions. Teaching moments included everything from learning to count, to learning how to rub chalk off a blackboard. Typically the older siblings would launch into a teaching moment unasked, although sometimes the younger child requested instructions. This image is for illustrative purposes only.

Great study and we need more like this one,because practice in kindergartens showed that mixed group(where children were put together as group even they wasn't equal by age) was more stimulating environment for children that were younger and had some kind of development delay.

Discovery of a New Means to Erase Pain

Full article at

A study published in the scientific journal Nature Neuroscience by Yves De Koninck and Robert Bonin, two researchers at Université Laval, reveals that it is possible to relieve pain hypersensitivity using a new method that involves rekindling pain so that it can subsequently be erased. This discovery could lead to novel means to alleviate chronic pain.

Huntington’s Disease Protein Helps Wire the Young Brain

Full article at

The protein that is mutated in Huntington’s disease is critical for wiring the brain in early life, according to a new Duke University study.

Brains of 5-week-old mice whose Htt was deleted show signs of cellular stress — reactive astrocytes (green) and microglia (white and red) and faulty connections — in brain circuits that have already been linked to the disease.

Dodging Dots Helps Explain Brain Circuitry

Full article at

In a new study, Brown University neuroscientists looked cell-by-cell at the brain circuitry that tadpoles, and possibly other animals, use to avoid collisions. The study produced a model of how individual inhibitory and excitatory neurons can work together to control a simple behavior.

The research is in European Journal of Neuroscience. (full access paywall)

Research: “Excitation and inhibition in recurrent networks mediate collision avoidance in Xenopus tadpoles” by Arseny S. Khakhalin, David Koren, Jenny Gu, Heng Xu and Carlos D. Aizenman in European Journal of Neuroscience. doi:10.1111/ejn.12664

Image: Researchers found that tadpoles use the optic tectum region of their brain to determine that something is approaching and avoid collision. The finding helps scientists better understand how different neurons work together to control simple behavior in many animals. Credit Arseny Khakhalin.

Sleep Deprivation Leads to Symptoms of Schizophrenia

Full article at

Twenty-four hours of sleep deprivation can lead to conditions in healthy persons similar to the symptoms of schizophrenia. This discovery was made by an international team of researchers under the guidance of the University of Bonn and King’s College London. The scientists point out that this effect should be investigated more closely in persons who have to work at night. In addition, sleep deprivation may serve as a model system for the development of drugs to treat psychosis. The results have now been published in The Journal of Neuroscience.

Image: The researchers examined a total of 24 healthy patients in a sleep lab. During the initial run, the subjects slept normally. One week later, the subjects were kept awake all night with a range of activities. This image is for illustrative purposes only. Credit Mikael Häggström.

People with Bipolar Disorder are Bigger Risk Takers

Full article at

Research led by The University of Manchester has shown that circuits in the brain involved in pursuing and relishing rewarding experiences are more strongly activated in people with bipolar disorder – guiding them towards riskier gambles and away from safer ones.

The research is in Brain. (full open access)

And it's called a 'Disorder'? Probably by those 'Normal' ones.

Doctors Have Ethical Obligation to Educate, Protect Athletes from Concussion

Full article at

The American Academy of Neurology (AAN), the largest professional association of neurologists and a leading authority on sports concussion, is releasing a new position paper that states doctors have an ethical obligation to educate and protect athletes from sports concussion and clear them to play only when the athlete is medically ready, standing firm against objections from players, parents or coaches. The statement is published in the July 9, 2014, online issue of Neurology, the medical journal of the AAN, and is being released ahead of The Sports Concussion Conference, July 11-13, 2014, in Chicago, where the AAN will share the latest scientific advances in diagnosing and treating sports concussion.

Russell, and Daniel Larriviere , On behalf of the Ethics, Law, and Humanities Committee, a Joint Committee of the American Academy of Neurology, American Neurological Association, and Child Neurology Society in Neurology. doi:10.1212/WNL.0000000000000613

Image: The statement concludes that physicians caring for athletes during and after a sports-related concussion should have adequate training and experience in the recognition and evaluation of both the existence and severity of potential brain injury.

Study Cracks How the Brain Processes Emotions

Although feelings are personal and subjective, the human brain turns them into a standard code that objectively represents emotions across different senses, situations and even people, reports a new study by Cornell University neuroscientist Adam Anderson.

Study Shows Link Between Inflammation in Maternal Blood and Schizophrenia in Offspring

Full article at

Maternal inflammation as indicated by the presence in maternal blood of early gestational C-reactive protein—an established inflammatory biomarker—appears to be associated with greater risk for schizophrenia in offspring, according to researchers at Columbia University’s Mailman School of Public Health, Columbia University Medical Center, and the New York State Psychiatric Institute. The study, “Elevated Maternal C-Reactive Protein and Increased Risk of Schizophrenia in a National Birth Cohort,” is published online in the American Journal of Psychiatry.
