(Medical Xpress)—Hopes for a cure for many brain diseases may rest on the humble mouse, now that scientists can map the rodents' brains more thoroughly than ever before. http://medicalxpress.com/news/2013-04-australian-scientists-mouse-brains-greatest.html Neuroscience Mon, 29 Apr 2013 08:40:01 EST news286440906 When people see pictures of bodies, a whole range of brain regions are active. This network is altered in women with anorexia nervosa. In a functional magnetic resonance imaging study, two regions that are important for the processing of body images were functionally more weakly connected in anorexic women than in healthy women. The stronger this "connection error" was, the more overweight the respondents considered themselves. http://medicalxpress.com/news/2013-01-error-brains-anorexics.html Psychology & Psychiatry Thu, 24 Jan 2013 11:09:04 EST news278248116 New evidence indicates that Parkinson's disease is preceded by a period during which healthy regions of the brain take over the functions of damaged ones. Neurologist Bart van Nuenen performed a unique study involving people who are clinically still healthy and free from disease manifestations, but who have an increased risk of developing Parkinson's disease later in life due to their genetic predisposition. Van Nuenen will defend his PhD thesis based on this study on 22 November. http://medicalxpress.com/news/2012-11-compensation-brain-treatment.html Parkinson's & Movement disorders Tue, 13 Nov 2012 08:18:33 EST news272017099 When people – and monkeys – look at faces, a special part of their brain that is about the size of a blueberry "lights up." Now, the most detailed brain-mapping study of the area yet conducted has confirmed that it isn't limited to processing faces, as some experts have maintained, but instead serves as a general center of expertise for visual recognition. Neuroscientists previously established that this region, which is called the fusiform face area (FFA) and is located in the temporal lobe, is responsible for a particularly effective form of visual recognition. But there has been an ongoing debate about whether this area is hard-wired to recognize faces because of their importance to us or if it is a more general mechanism that allows us to rapidly recognize objects that we work with extensively. http://medicalxpress.com/news/2012-10-brain-auto-experts-cars-people.html Neuroscience Mon, 01 Oct 2012 15:00:10 EST news268308899 MRI brain scans no longer just show the various regions of brain activity; nowadays the networks in the brain can now be imaged with ever greater precision. This will make functional MRI (fMRI) increasingly powerful in the coming years, leading to tools that can be used in cognitive neuroscience. This is the claim made by Prof. David Norris in his inaugural lecture as Professor of Neuroimaging at the University of Twente on 13 September. http://medicalxpress.com/news/2012-09-imaging-network-traffic-brains.html Neuroscience Tue, 18 Sep 2012 08:20:09 EST news267175200 A powerful new imaging technique called High Definition Fiber Tracking (HDFT) will allow doctors to clearly see for the first time neural connections broken by traumatic brain injury (TBI) and other disorders, much like X-rays show a fractured bone, according to researchers from the University of Pittsburgh in a report published online today in the Journal of Neurosurgery. http://medicalxpress.com/news/2012-03-high-definition-fiber-tracking-reveals.html Surgery Fri, 02 Mar 2012 04:50:03 EST news249884660 (Medical Xpress) -- Scientists at Washington University School of Medicine are using a new imaging device that simultaneously performs positron-emission tomography (PET) and magnetic resonance imaging (MRI) scans, producing more detailed images than either technique alone. http://medicalxpress.com/news/2012-02-combination-pet-mri-scanner-imaging-frontiers.html Other Thu, 16 Feb 2012 06:23:46 EST news248595807 A new study using MRI scans, led by Professor Jianfeng Feng, from the University of Warwick's Department of Computer Science, has found that depression frequently seems to uncouple the brain's "Hate Circuit". The study entitled "Depression Uncouples Brain Hate Circuit" is published today in the journal Molecular Psychiatry. http://medicalxpress.com/news/2011-10-mri-depression-uncouples-brain-circuit.html Psychology & Psychiatry Tue, 04 Oct 2011 04:46:36 EST news236922372 A team of researchers says it has discovered why so many people undergoing magnetic resonance imaging (MRI), especially in newer high-strength machines, get vertigo, or the dizzy sensation of free-falling, while inside or when coming out of the tunnel-like machine. http://medicalxpress.com/news/2011-09-mri-vertigo-machine-magnetic-field.html Medical research Thu, 22 Sep 2011 12:00:06 EST news235898177
