A team of researchers at the University of Calgary's Hotchkiss Brain Institute (HBI) have discovered that adult brain cell production might be determined, in part, by the early parental environment. The study suggests that dual parenting may be more beneficial than single parenting. http://medicalxpress.com/news/2013-05-brain-parents.html Medical research Wed, 01 May 2013 17:00:02 EST news286628529 Researchers at the University of Alabama at Birmingham (UAB) report that children with cerebral palsy who underwent Constraint Induced Movement therapy (CI therapy) saw a significant increase in grey matter volume in areas of the brain associated with movement. The findings, published online April 22, 2013 in Pediatrics, are the first to show that structural remodeling of the brain occurs during rehabilitation in a pediatric population. http://medicalxpress.com/news/2013-04-ci-therapy-grey-brains-children.html Neuroscience Tue, 23 Apr 2013 10:00:01 EST news285929203 A series of studies demonstrate improved detection of the second most common form of dementia, providing diagnostic specificity that clears the way for refined clinical trials testing targeted treatments. The new research is being presented by experts from the Perelman School of Medicine at the University of Pennsylvania at the American Academy of Neurology's 65th Annual Meeting in San Diego March 16-23, 2013. http://medicalxpress.com/news/2013-03-frontotemporal-degeneration-aid-clinical-trial.html Neuroscience Fri, 15 Mar 2013 11:55:17 EST news282567309 People who take cocaine over many years without becoming addicted have a brain structure which is significantly different from those individuals who developed cocaine-dependence, researchers have discovered. New research from the University of Cambridge has found that recreational drug users who have not developed a dependence have an abnormally large frontal lobe, the section of the brain implicated in self-control. Their research was published in the journal Biological Psychiatry. http://medicalxpress.com/news/2013-01-people-cocaine-differently-brain-addiction.html Psychology & Psychiatry Thu, 17 Jan 2013 13:14:16 EST news277650845 Researchers supported by the Wellcome Trust have discovered that we use a different part of our brain to learn about social hierarchies than we do to learn ordinary information. The study provides clues as to how this information is stored in memory and also reveals that you can tell a lot about how good somebody is likely to be at judging social rank by looking at the structure of their brain. http://medicalxpress.com/news/2012-11-dog-reveals-brain-social.html Neuroscience Thu, 08 Nov 2012 12:44:57 EST news271601089 Teenage girls with severe antisocial behaviour show abnormal changes in the structure of their brains, according to a study published today. The findings support previous studies in boys that suggested the brains of teenagers with behaviour problems may operate differently, and they could also explain why boys are more likely than girls to develop behaviour problems. http://medicalxpress.com/news/2012-10-reveals-brain-teenage-girls-severe.html Psychology & Psychiatry Wed, 24 Oct 2012 08:10:50 EST news270285013 (Medical Xpress)—Researchers from Stanford and Israel's Bar Ilan University have found that differences in the rates at which white matter develops in children's brains may, as they write in their paper published in the Proceedings of the National Academy of Sciences, account for differences in their ability to learn to read. http://medicalxpress.com/news/2012-10-year-significant-differences-white-children.html Neuroscience Tue, 09 Oct 2012 12:20:01 EST news269001046 Scientists at Charité – Universitätsmedizin Berlin have succeeded in coming closer to determining the risk of relapse in detoxified alcohol-dependent patients. Using an imaging process (magnetic resonance tomography) it was shown that particular regions in the brain demonstrate structural as well as functional abnormalities in relapsed alcohol-dependent patients. Study findings are published in the journal Archives of General Psychiatry. http://medicalxpress.com/news/2012-09-functional-abnormalities-brains-relapsed-alcohol-dependent.html Psychology & Psychiatry Thu, 20 Sep 2012 13:03:15 EST news267364988 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 (Medical Xpress)—Working as a piano tuner may lead to changes in the structure of the memory and navigation areas of the brain, suggests new research funded by the Wellcome Trust. In a study published today in the 'Journal of Neuroscience', scientists show that these structural differences correlate with the number of years of experience a piano tuner has. http://medicalxpress.com/news/2012-08-tuning-brain-piano.html Neuroscience Wed, 29 Aug 2012 06:07:56 EST news265439270 Children who suffer or witness physical abuse undergo changes to their brain structure that may predispose them to depression and substance abuse later in life, a study said Wednesday. http://medicalxpress.com/news/2012-08-child-abuse-disrupts-brain-depression.html Psychology & Psychiatry Wed, 01 Aug 2012 09:50:47 EST news263033417 (Medical Xpress) -- New research from Uppsala University, Sweden, suggests that an active lifestyle in late life protects grey matter and cognitive functions in humans. The findings are now published in the scientific journal Neurobiology of Aging. http://medicalxpress.com/news/2012-05-lifestyle-elderly-brains.html Neuroscience Tue, 15 May 2012 05:57:38 EST news256280226 New research by scientists at the University of Cambridge suggests that chronic cocaine abuse accelerates the process of brain ageing. The study, published today 25 April in Molecular Psychiatry, found that age-related loss of grey matter in the brain is greater in people who are dependent on cocaine than in the healthy population. http://medicalxpress.com/news/2012-04-chronic-cocaine-aging-brain.html Addiction Tue, 24 Apr 2012 07:32:49 EST news254471547 Australian researchers have found evidence that heart failure is associated with a decline in people's mental processes and a loss of grey matter in the brain. These changes can make it more difficult for heart failure (HF) patients to remember and carry out instructions such as taking the correct medication at the right times. http://medicalxpress.com/news/2012-01-heart-failure-loss-brain-cells.html Cardiology Tue, 31 Jan 2012 19:00:03 EST news247248547 Medical researchers at the University of Alberta have discovered a new way to track the progression of multiple sclerosis (MS) in those living with the disease, by using a powerful, triple strength MRI to track increasing levels of iron found in brain tissue. http://medicalxpress.com/news/2011-12-powerful-mri-track-iron-brain.html Neuroscience Thu, 15 Dec 2011 13:27:46 EST news243178058 Researchers at the University of Cambridge have identified abnormal brain structures in the frontal lobe of cocaine users' brains which are linked to their compulsive cocaine-using behaviour.
