Researchers recently found that such mice had enhanced learning and memory when compared with normal mice that hadn't received the transplanted human cells. The findings indicate that these supportive cells, called glia, play an important role in human cognition.Thu, 07 Mar 2013 12:39:39 EST shields children from stress, research indicates Exercise may play a key role in helping children cope with stressful situations, according to a recent study.Thu, 07 Mar 2013 09:15:15 EST of a single molecular switch makes an old mouse brain young The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse.Wed, 06 Mar 2013 13:42:42 EST the 'Cocktail Party Problem': How we can focus on one speaker in noisy crowds In the din of a crowded room, paying attention to just one speaker's voice can be challenging. Research demonstrates how the brain homes in on one speaker to solve this "Cocktail Party Problem." Researchers discovered that brain waves are shaped so the brain can selectively track the sound patterns from the speaker of interest while excluding competing sounds from other speakers. The findings could have important implications for helping individuals with a range of deficits.Wed, 06 Mar 2013 13:42:42 EST intervention improves mood symptoms in children and adolescents at risk for bipolar disorder Psychologists have found that children and adolescents with major depression or subthreshold forms of bipolar disorder - and who had at least one first-degree relative with bipolar disorder - responded better to a 12-session family-focused treatment than to a briefer educational treatment.Wed, 06 Mar 2013 08:41:41 EST in reading foreign languages Recent research into how we learn is set to help people in their efforts to read a second or foreign language (SFL) more effectively.

Is mom's obsession normal? A new mother may constantly worry and check to see if her baby is breathing. Or she may obsess about germs. A new study found postpartum moms have a much higher rate of obsessive-compulsive symptoms than the general population. This is the first large-scale study of obsessive-compulsive symptoms in new moms. The symptoms could result from hormonal changes or be adaptive, but may indicate a psychological disorder if they interfere with a mother's functioning.Mon, 04 Mar 2013 15:18:18 EST emerges in children on the autism spectrum with severe language delay at greater rate than previously thought Study could reveals key predictors of speech gains. New findings reveal that 70 percent of children with autism spectrum disorders (ASD) who have a history of severe language delay, achieved phrase or fluent speech by age eight.Mon, 04 Mar 2013 10:49:49 EST takes a toll well into adulthood The first large, population-based study to follow children with attention-deficit hyperactivity disorder into adulthood shows that ADHD often doesn?t go away and that children with ADHD are more likely to have other psychiatric disorders as adults. They also appear more likely to commit suicide and to be incarcerated as adults.Mon, 04 Mar 2013 10:47:47 EST during pregnancy and stress in puberty play key role in development of schizophrenia The interplay between an infection during pregnancy and stress in puberty plays a key role in the development of schizophrenia, as behaviorists demonstrate in a mouse model. However, there is no need to panic.Fri, 01 Mar 2013 12:25:25 EST children more exposed to alcohol promotion than adults, experts warn Children in Britain are more exposed to alcohol promotion than adults and need much stronger protection, warn experts.Thu, 28 Feb 2013 19:46:46 EST video games boost reading skills, study of children with dyslexia suggests Much to the chagrin of parents who think their kids should spend less time playing video games and more time studying, time spent playing action video games can actually make dyslexic children read better, new research suggests. In fact, 12 hours of video game play did more for reading skills than is normally achieved with a year of spontaneous reading development or demanding traditional reading treatments.Thu, 28 Feb 2013 12:41:41 EST personal relationships could help teens overcome learning disabilities A new study from Israel says that children with learning disabilities develop less secure attachments with mothers and teachers, and that closer and more secure relationships with parents and adults may help them overcome these disabilities.Thu, 28 Feb 2013 11:34:34 EST junk food while pregnant may make your child a junk food addict A healthy diet during pregnancy is critical to the future health of your children. New research suggests that pregnant mothers who consume junk food cause developmental changes of the opioid signaling pathway in the brains of their unborn children. Consequently, these children are less sensitive to opioids released upon consumption of foods high in fat and sugar, and need to eat more to achieve a "feel good" response.Thu, 28 Feb 2013 10:34:34 EST with autism show increased positive social behaviors when animals are present The presence of an animal can significantly increase positive social behaviors in children with autism spectrum disorders, according to new research.Wed, 27 Feb 2013 18:35:35 EST epics were written in 762 BCE, give or take, new study suggests One of literature's oldest mysteries is a step closer to being solved. A new study dates Homer's The Iliad to 762 BCE and adds a quantitative means of testing ideas about history by analyzing the evolution of language.Wed, 27 Feb 2013 18:33:33 EST children for their personal qualities may backfire Praising children, especially those with low self-esteem, for their personal qualities rather than their efforts may make them feel more ashamed when they fail, according to new research.Wed, 27 Feb 2013 18:33:33 EST grade math skills set foundation for later math ability Children who failed to acquire a basic math skill in first grade scored far behind their peers by seventh grade on a test of the mathematical abilities needed to function in adult life, according to researchers.Wed, 27 Feb 2013 15:13:13 EST explores factors that impact adolescent mental health Research indicates that half of all lifetime cases of mental illness begin by age 14, well before adulthood. Three new studies investigate the cognitive, genetic and environmental factors that may contribute to mental health disorders in adolescence.Wed, 27 Feb 2013 15:12:12 EST Develop digital games to improve brain function and well-being Neuroscientists should help to develop compelling digital games that boost brain function and improve well-being, say two professors specializing in the field.Wed, 27 Feb 2013 13:43:43 EST connects early childhood with pain, depression in adulthood New research examines how childhood socioeconomic disadvantages and maternal depression increase the risk of major depression and chronic pain when they become adults.Wed, 27 Feb 2013 12:19:19 EST studies link gene to selfish behavior in kids, find other children natural givers Most parents would agree that raising a generous child is an admirable goal -- but how, exactly, is that accomplished? New results shed light on how generosity and related behaviors -- such as kindness, caring and empathy -- develop, or don't develop, in children from 2 years old through adolescence.Wed, 27 Feb 2013 10:29:29 EST'Network' analysis of brain may explain features of autism A look at how the brain processes information finds distinct pattern in autistic children. Using EEGs to track the brain's electrical cross-talk, researchers found structural difference in brain connections. Compared with neurotypical children, those with autism have multiple redundant connections between neighboring brain areas at expense of long-distance links. The study, using "network analysis" like with airlines or electrical grids, may help in understanding some classic autistic behaviors.Wed, 27 Feb 2013 10:20:20 EST risk of sleep disorder narcolepsy in children who received swine flu vaccine A study finds an increased risk of narcolepsy in children and adolescents who received the A/H1N1 2009 influenza vaccine (Pandemrix) during the pandemic in England.Tue, 26 Feb 2013 19:40:40 EST reinforces learning: Children?s brains transform subconsciously learned material into active knowledge During sleep, our brains store what we have learned during the day a process even more effective in children than in adults, new research shows.Tue, 26 Feb 2013 08:11:11 EST levels of several toxic metals found in children with autism Researchers have found significantly higher levels of toxic metals in children with autism, compared to typical children.

Linguistics and biology now researchers propose a new theory on the deep roots of human speech.Thu, 21 Feb 2013 14:16:16 EST life stress may take early toll on heart function Early life stress like that experienced by ill newborns appears to take an early toll of the heart, affecting its ability to relax and refill with oxygen-rich blood, researchers report.Thu, 21 Feb 2013 10:43:43 EST pathway linked to fetal alcohol risk: Molecular switch promises new targets for diagnosis and therapy Scientists have identified a molecular signaling pathway that plays an important role in the development of fetal alcohol spectrum disorder.Wed, 20 Feb 2013 17:07:07 EST children can suffer lasting psychological harm as adults Bullied children grow into adults who are at increased risk of developing anxiety disorders, depression and suicidal thoughts, according to a new study.Wed, 20 Feb 2013 16:36:36 EST with brain lesions able to use gestures important to language learning Children with brain lesions suffered before or around the time of birth are able to use gestures -- an important aspect of the language learning process -- to convey simple sentences.Wed, 20 Feb 2013 12:34:34 EST movement to 'dry run' mental imagery enhances performance Adding movement to mental rehearsal can improve performance finds a new study. For high jumpers the study shows that dynamic imagery improves the number of successful attempts and the technical performance of jumps The technique of mental rehearsal is used to consolidate performance in many disciplines including music and sport. Motor imagery and physical practice use overlapping neural networks in the brain and the two together can improve performance as well as promoting recovery from injury.Tue, 19 Feb 2013 20:15:15 EST marker of dyslexia discovered: Ability to consistently encode sound undergirds the reading process Researchers believe they have discovered a biological marker of dyslexia, a disorder affecting up to one out of 10 children that makes learning to read difficult. The researchers found a systematic relationship between reading ability and the consistency with which the brain encodes sounds. The good news: Response consistency can be improved with auditory training.Tue, 19 Feb 2013 17:21:21 EST protein differs in males, females Male rat pups have more of a specific brain protein associated with language development than females, according to a new study. The study also found sex differences in the brain protein in a small group of children. The findings may shed light on sex differences in communication in animals and language acquisition in people.Tue, 19 Feb 2013 17:21:21 EST in poverty show different physiological vulnerabilities to the care-giving environment Some infants raised in poverty exhibit physical traits that make them more vulnerable to poor care-giving, according to new research. The combination of physiological vulnerability and poor care-giving may lead these children to show increased problem behaviors later in childhood.Tue, 19 Feb 2013 14:10:10 EST therapy improves behavior in children with autism, study suggests Weekly music therapy sessions can have a positive effect on behavior in children with autism, reports a new article. In a study of 41 children, improvements were seen particularly in inattentive behaviors over a ten month period.Tue, 19 Feb 2013 14:01:01 EST risk of preterm birth for pregnant women vaccinated during pandemic flu Pregnant women who received the H1N1 influenza vaccine during the 2009 pandemic were less likely to have premature babies, and their babies weighed more on average.Tue, 19 Feb 2013 12:13:13 EST, shared activities are 'game changers' for dad/daughter relationships The most frequent turning point in father-daughter relationships is shared activity -- especially sports -- ahead of such pivotal events as when a daughter marries or leaves home, according to a new study.Tue, 19 Feb 2013 12:12:12 EST there a link between childhood obesity and ADHD, learning disabilities? A new study has established a possible link between high-fat diets and such childhood brain-based conditions as attention deficit hyperactivity disorder (ADHD) and memory-dependent learning disabilities.Tue, 19 Feb 2013 12:10:10 EST with auditory processing disorder may now have more treatment options Researchers are helping children with auditory processing disorder receive better treatment.

Most parents carefully select what television programs and movies their children can watch. But a psychologist says educational shows could come with an added lesson that influences a child?s behavior. Children exposed to educational programs were more aggressive in their interactions than those who weren't exposed.Tue, 19 Feb 2013 10:21:21 EST, anger or pain: Why do babies cry? Researchers have studied adults' accuracy in the recognition of the emotion causing babies to cry. Eye movement and the dynamic of the cry play a key role in recognition. It is not easy to know why a newborn cries, especially amongst first-time parents. Although the main reasons are hunger, pain, anger and fear, adults cannot easily recognize which emotion is the cause of the tears.Tue, 19 Feb 2013 09:06:06 EST new light on infant brain development A new study finds that the infant brain does not control its blood flow the same way as the adult brain, that the control of brain blood flow develops with age. These findings could change the way researchers study brain development in infants and children.Mon, 18 Feb 2013 16:41:41 EST TV in childhood linked to long-term antisocial behavior, New Zealand study shows Children and adolescents who watch a lot of television are more likely to manifest antisocial and criminal behavior when they become adults, according to a new study.Mon, 18 Feb 2013 09:27:27 EST stress responses may lead to obesity in children Children who overreact to stressors may be at risk of becoming overweight or obese, according to researchers.Sun, 17 Feb 2013 08:53:53 EST billboards driving us to distraction? There's a billboard up ahead, a roadside sign full of language and imagery. Next stop: the emotionally distracted zone.Thu, 14 Feb 2013 13:40:40 EST therapy for children with autism can impact brain function Using functional magnetic resonance imaging for before-and-after analysis, a team of researchers discovered positive changes in brain activity in children with autism who received a particular type of behavioral therapy.Thu, 14 Feb 2013 12:06:06 EST babies know their grammar by 7 months Babies as young as seven months can distinguish between, and begin to learn, two languages with vastly different grammatical structures, according to new research.Thu, 14 Feb 2013 11:16:16 EST of language in human and bird biology: Genes activated for human speech similar to ones used by singing songbirds The neuroanatomy of human speech and bird song share structural features, behaviors and now gene expression patterns.Thu, 14 Feb 2013 11:16:16 EST
