Neurosurgeons at the Krembil Neuroscience Centre, Toronto Western Hospital, have for the first time, initiated the restoration of lost brain tissue through brain bypass surgery in patients where blood flow to the brain is impaired by cerebrovascular disease. The study, which involved 29 patients, was published online in the journal Stroke. http://phys.org/news222338029.html Medicine & Health Mon, 18 Apr 2011 09:34:01 EST news222338029 (PhysOrg.com) -- In a paper published in Proceedings of National Academy of Sciences, Veronica Kwok, Li-Hai Tan, and their colleagues at the University of Hong Kong, conclude that the adult human brain is capable of new rapid growth when exposed to stimuli similar to what babies experience as they are learning from their environment. http://phys.org/news221214776.html Medicine & Health Tue, 05 Apr 2011 09:33:37 EST news221214776 Research suggests that intelligence in humans is controlled by the part of the brain known as the 'cortex', and most theories of age-related cognitive decline focus on cortical dysfunction. However, a new study of Scottish older adults, reported in the April 2011 issue of Cortex, suggests that grey matter volume in the 'cerebellum' at the back of the brain predicts cognitive ability, and keeping those cerebellar networks active may be the key to keeping cognitive decline at bay. http://phys.org/news218811034.html Medicine & Health Tue, 08 Mar 2011 12:50:49 EST news218811034 (PhysOrg.com) -- Participating in an 8-week mindfulness meditation program appears to make measurable changes in brain regions associated with memory, sense of self, empathy and stress. In a study that will appear in the January 30 issue of Psychiatry Research: Neuroimaging, a team led by Massachusetts General Hospital (MGH) researchers report the results of their study, the first to document meditation-produced changes over time in the brain's grey matter. http://phys.org/news214839934.html Medicine & Health Fri, 21 Jan 2011 13:48:03 EST news214839934 (PhysOrg.com) -- McGill University researchers have presented three studies suggesting depending on GPS to navigate may have a negative effect on brain function, especially on the hippocampus, which is involved in memory and navigation processes. http://phys.org/news209275116.html Medicine & Health Thu, 18 Nov 2010 06:40:01 EST news209275116 A large academic study has demonstrated structural changes in specific brain regions in female patients with irritable bowel syndrome (IBS), a condition that causes pain and discomfort in the abdomen, along with diarrhea, constipation or both. http://phys.org/news199028106.html Medicine & Health Thu, 22 Jul 2010 14:35:22 EST news199028106 (PhysOrg.com) -- New research from the UK has found that teenagers and young adults find it hard to concentrate because their brains are more similar to those of much younger children than those of mature adults, with more grey matter but lower efficiency. The findings suggest the brain is not fully developed until people reach their late twenties or even early thirties, which is much later than previously thought. http://phys.org/news194674084.html Medicine & Health Wed, 02 Jun 2010 08:10:01 EST news194674084 (PhysOrg.com) -- We know more about the cosmos than we do about the human brain, but work by European researchers will now allow scientists to probe further into the mysteries of our grey matter. http://phys.org/news192451751.html Medicine & Health Fri, 07 May 2010 12:10:07 EST news192451751 Eating fish -- long considered 'brain food' -- may really be good for the old grey matter, as is a healthy dose of sunshine, new research suggests. http://phys.org/news162107255.html Medicine & Health Thu, 21 May 2009 06:48:14 EST news162107255 February's brutal chimpanzee attack, during which a pet chimp inflicted devastating injuries on a Connecticut woman, was a stark reminder that chimps are much stronger than humans—as much as four-times stronger, some researchers believe. But what is it that makes our closest primate cousins so much stronger than we are? One possible explanation is that great apes simply have more powerful muscles. Indeed, biologists have uncovered differences in muscle architecture between chimpanzees and humans. But evolutionary biologist Alan Walker, a professor at Penn State University, thinks muscles may only be part of the story. http://phys.org/news157653323.html Biology Mon, 30 Mar 2009 17:38:03 EST news157653323
