Key brain networks may differ in autism Neural systems tied to gauging social cues appear 'over-connected' in children with the disorder.
Either/Or? Either/Or seems like a firm, strong, defensible assertion, consistent with existential thought and appealing to those of us who long for simple (simplistic?) answers. But some of the most interesting and important matters aren't so readily disposed of. read more
It's your own time you're wasting British teachers have voted to receive training in neuroscience "˜to improve classroom practice' according to a report in the Times Educational Supplement and the debate sounded like a full-on serial head-desker. The idea of asking for neuroscience training at all sounds a little curious but the intro seemed like it could be quite reasonable: Members [...]

Atypical brain connectivity associated with autism spectrum disorder Autism spectrum disorder in adolescents appears to be associated with atypical connectivity in the brain involving the systems that help people infer what others are thinking and understand the meaning of others' actions and emotions. The ability to navigate and thrive in complex social systems is commonly impaired in ASD, a neurodevelopmental disorder affecting as many as 1 in 88 children.
Off-season doesn't allow brain to recover from football hits, study says Six months off may not be long enough for the brains of football players to completely heal after a single season, putting them at even greater risk of head injury the next season. "I don't want to be an alarmist, but this is something to be concerned about," said the lead researcher. The analysis revealed that white matter changes in the players' brains started to look different from the control group when players experienced as few as 10 to 15 head impacts.
Intravenously administered ketamine shown to reduce symptoms of chronic post-traumatic stress disorder For the first time, evidence that a single dose of IV-administered ketamine was associated with the rapid reduction of symptoms of post-traumatic stress disorder in patients with chronic PTSD was demonstrated in a proof-of-concept, randomized, double blind crossover study. These findings could be the first step toward developing new interventions for PTSD.
Beating the clock for ischemic stroke sufferers Researchers have developed a new computer tool to ensure faster care and treatment for stroke patients. The CAD stroke technology is capable of detecting signs of stroke from computed tomography (CT) scans. A CT scan uses X-rays to take pictures of the brain in slices. When blood flow to the brain is blocked, an area of the brain turns softer or decreases in density due to insufficient blood flow, pointing to an ischemic stroke.
In old age, lack of emotion, interest may signal brain is shrinking Older people who have apathy but not depression may have smaller brain volumes than those without apathy, according to a new study. Apathy is a lack of interest or emotion.
Men Without Beards Could Soon Have An Evolutionary Advantage Hipsters take note: Beards may be all the rage — and they might be making you more attractive for now — but this is a fashion trend that could ultimately be the cause of its own undoing....
How to Live a Purposeful and Fulfilling Life? In his book The Promise of a Pencil, Adam Braun, founder of Pencils of Promise, shares how in following his dream he found purpose in life. Adam Braun's experience reminds us how there is a leader in all of us and how fulfillment in life is achieved when we make a contribution larger than ourselves to the more
How kids' brain structures grow as memory develops Our ability to store memories improves during childhood, associated with structural changes in the hippocampus and its connections with prefrontal and parietal cortices. New research is exploring how these brain regions develop at this crucial time. Eventually, that could give insights into disorders that typically emerge in the transition into and during adolescence and affect memory, such as schizophrenia and depression.
Cancer drugs block dementia-linked brain inflammation, study finds A class of drugs developed to treat immune-related conditions and cancer -- including one currently in clinical trials for glioblastoma and other tumors -- eliminates neural inflammation associated with dementia-linked diseases and brain injuries, according to researchers. In their study, the researchers discovered that the drugs, which can be delivered orally, eradicated microglia, the primary immune cells of the brain. These cells exacerbate many neural diseases, including Alzheimer's and Parkinson's, as well as brain injury.
How smells stick to your memories: Your nose can be a pathfinder Waves in your brain make smells stick to your memories and inner maps. Researchers have recently discovered the process behind this phenomenon. The brain, it turns out, connects smells to memories through an associative process where neural networks are linked through synchronized brain waves of 20-40 Hz.
When Was the Last Time You Felt Schadenfreude, and What Did It Mean? So you've suffered an embarrassing and public setback, and the people who dislike you are rejoicing. Their glee at your misfortune is called schadenfreude. Should you hang your head in shame, or should you consider their happiness a huge compliment? ...
Scientists explain how memories stick together A new model of memory that explains how neurons retain select memories a few hours after an event has been uncovered by researchers. This new framework provides a more complete picture of how memory works, which can inform research into disorders liked Parkinson's, Alzheimer's, post-traumatic stress and learning disabilities.
Early Recollections and the Five Senses People with an orientation to particular senses serve to remind us all how an attunement to sensory experiences contributes to vitality in living and an appreciation of our sensory endowments. How we experience the senses in early recollections relates to the uniqueness of individuals and their capacity for revealing glimpses into human more
Executive Pathologies – The Relationship Between CEO Narcissism and Fraud Research suggests an association between CEO personality traits and fraudulent behavior. Narcissism has been linked to manipulation of financial results, which has implications for the executive selection process, board oversight, and the structuring of executive compensation packages. The celebration of financial misconduct in movies like The Wolf of Wall Street tends to focus on the [...]

Are Babies Born With An Existing Structure Of Language? A new study finds evidence that we are born with fundamental knowledge about language, helping to explain one of our greatest abilities.Researchers in the US and Italy have found that newborn infants between two- and five-days-old already prefer syllables which are more "˜word-like' over those not usually found in human languages (Gomez et al., 2014).In the study, the researchers played back "˜good' and "˜bad' words to the newborns while using near-infrared spectroscopy to monitor the oxygenation of the blood in their brains.An example of a "˜good' syllable is "˜bl' which is found in many languages around the world: there's blando in Italian, blusa in Spanish and blink in English, amongst many, many other examples.In contrast, a "˜bad' syllable is "˜lb' which is a much less frequent combination found in low frequencies in few languages (including Russian).The idea is that we have an inbuilt tendency to prefer particular basic building-blocks of language over others.In the example above we prefer "˜bla' over "˜lba'.The question is whether we are born with this preference or is it something that we learn with exposure to language over time.The new study supports the idea that these preferences for certain types of syllables are inborn.Infants who haven't even learned how to babble yet seem to be born with a sense of how words should sound.One of the study's authors, Professor Iris Berent said:"The results of this new study suggest that, the sound patterns of human languages are the product of an inborn biological instinct, very much like birdsong,"This helps explain similarities in the structure of many languages, since they are likely based on common inbuilt preference for how languages should sound at a very basic level.That's why babies can arrive in the world and be confident that whatever language those around them speak, they will be able to pick it up.
