Using MRI, neuroscientists at Georgetown University Medical Center found significant differences in brain anatomy when comparing men and women with dyslexia to their non-dyslexic control groups, suggesting that the disorder may have a different brain-based manifestation based on sex. http://medicalxpress.com/news/2013-05-brain-anatomy-dyslexia-men-women.html Neuroscience Wed, 08 May 2013 13:02:28 EST news287236941 (Medical Xpress)—The reason why some people are worse at learning than others has been revealed by a research team from Berlin, Bochum, and Leipzig, operating within the framework of the Germany-wide network "Bernstein Focus State Dependencies of Learning". http://medicalxpress.com/news/2013-02-brain-sensory-sufficiently-team.html Neuroscience Wed, 13 Feb 2013 10:50:02 EST news279973192 Seizures during childhood fever are usually benign, but when prolonged, they can foreshadow an increased risk of epilepsy later in life. Now a study funded by the National Institutes of Health suggests that brain imaging and recordings of brain activity could help identify the children at highest risk. The study reveals that within days of a prolonged fever-related seizure, some children have signs of acute brain injury, abnormal brain anatomy, altered brain activity, or a combination. http://medicalxpress.com/news/2012-11-mri-eeg-children-epilepsy-febrile.html Neuroscience Wed, 07 Nov 2012 16:00:06 EST news271517906 Men and women with autism spectrum conditions (ASC) may show subtle but significant differences in the cognitive functions impacted by the condition, according to new research published Oct 17 by Meng-Chuan Lai and colleagues from the Autism Research Centre at the University of Cambridge, UK in the open access journal PLOS ONE. http://medicalxpress.com/news/2012-10-impact-autism-men-women.html Autism spectrum disorders Wed, 17 Oct 2012 17:00:03 EST news269710319 (Medical Xpress)—New research can identify the neural structures associated with poor reading skills in young children, and could lead to an early warning system for struggling students. http://medicalxpress.com/news/2012-10-brain-scans-children-ability.html Psychology & Psychiatry Thu, 11 Oct 2012 11:25:52 EST news269173546 Nearly 100 years after a British neurologist first mapped the blind spots caused by missile wounds to the brains of soldiers, Perelman School of Medicine researchers at the University of Pennsylvania have perfected his map using modern-day technology. Their results create a map of vision in the brain based upon an individual's brain structure, even for people who cannot see. Their result can, among other things, guide efforts to restore vision using a neural prosthesis that stimulates the surface of the brain. The study appears in the latest issue of Current Biology. http://medicalxpress.com/news/2012-10-universal-vision-human-brain.html Neuroscience Thu, 04 Oct 2012 12:00:06 EST news268570711 What makes a person altruistic? Philosophers throughout the ages often pondered the question but failed to get concrete answers. New research from the University of Zurich in Switzerland shows that the answer may lie in our brains, or more accurately, that the volume of a small brain region can influences one's predisposition for altruistic behaviour. The results, presented in the journal Neuron, indicate that individuals who behave more altruistically than others have more grey matter at the junction between the parietal and temporal lobe. This shows for the very first time that there is a connection between brain anatomy, brain activity and altruistic behaviour. http://medicalxpress.com/news/2012-09-volume-grey-degree-altruism.html Neuroscience Mon, 17 Sep 2012 07:52:59 EST news267087162 Determining when a teenage brain becomes an adult brain is not an exact science but it's getting closer, according to an expert in adolescent developmental psychology, speaking at the American Psychological Association's 120th Annual Convention. http://medicalxpress.com/news/2012-08-psychology-courts-policymakers-evidence-adolescents.html Psychology & Psychiatry Fri, 03 Aug 2012 16:30:27 EST news263230044 What can explain extreme differences in altruism among individuals, from Ebenezer Scrooge to Mother Teresa? It may all come down to variation in the size and activity of a brain region involved in appreciating others' perspectives, according to a study published in the July 12th issue of the journal Neuron. The findings also provide a neural explanation for why altruistic tendencies remain stable over time. http://medicalxpress.com/news/2012-07-individual-differences-altruism-brain-region.html Neuroscience Wed, 11 Jul 2012 12:00:02 EST news261222914 School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress. http://medicalxpress.com/news/2012-01-mom-good-child-brain.html Psychology & Psychiatry Mon, 30 Jan 2012 15:00:10 EST news247145926 Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study, published by Cell Press in the December 8 issue of the journal Neuron, reveals that functionally connected brain regions mature together and uncovers fascinating sex-specific differences in brain development. http://medicalxpress.com/news/2011-12-big-picture-long-term-imaging-reveals.html Neuroscience Wed, 07 Dec 2011 12:25:30 EST news242483118 Magnetic resonance tractography (MRT) is a valuable, noninvasive imaging tool for studying human brain anatomy and, as MRT methods and technologies advance, has the potential to yield new and illuminating information on brain activity and connectivity.

Before brain operations, neurosurgeons can now evaluate patient-specific surgical risks, achieve increased safety, and avoid unacceptable risks. http://medicalxpress.com/news/2011-05-fraunhofer-mevis-procedure-brain-surgery.html Other Fri, 27 May 2011 10:26:20 EST news225710770 Researchers at the University of Pittsburgh School of Medicine have developed a mouse model of major depressive disorder (MDD) that is based on a rare genetic mutation that appears to cause MDD in the majority of people who inherit it. The findings, which were published online today in the American Journal of Medical Genetics Part B: Neuropsychiatric Genetics EarlyView, could help to clarify the brain events that lead to MDD, and contribute to the development of new and better means of treatment and prevention. This report also illustrates an advance in the design of recombinant mouse models that should be applicable to many human diseases. http://medicalxpress.com/news/2011-05-mouse-depression.html Genetics Thu, 19 May 2011 04:04:30 EST news224996648
