In addition to allowing for more natural studies of brain activity in moving subjects, this implantable device represents a potential major step toward cord-free control of advanced prosthetics that move with the power of thought. The report is in the April 2013 issue of the Journal of Neural Engineering. http://medicalxpress.com/news/2013-03-wireless-implanted-sensor-broadens-range.html Neuroscience Tue, 19 Mar 2013 11:03:13 EST news282909706 Combining hospital MRIs with the mathematical tool known as network analysis, a group of researchers at UC San Francisco and UC Berkeley have mapped the three-dimensional global connections within the brains of seven adults who have genetic malformations that leave them without the corpus callosum, which connects the left and right sides of the brain. http://medicalxpress.com/news/2013-02-network-analysis-abnormal-brain-responsible.html Neuroscience Thu, 28 Feb 2013 16:20:52 EST news281290843 A new imaging method for the study of insulin-producing cells in diabetes among other uses is now being presented by a group of researchers at Umeå University in Sweden in the form of a video in the biomedical video journal, The Journal of Visualized Experiments. http://medicalxpress.com/news/2013-01-technology-diabetes.html Diabetes Mon, 21 Jan 2013 08:29:05 EST news277979331 A study based at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) finds that the local functional connectivity of the brain – the extent to which the activity of within a small brain region appears to be coordinated – is reduced in individuals with autism spectrum disorders (ASD). Although it has been recognized for several years that functional connectivity between separate areas of the brain was reduced in ASD, it had been assumed that local functional connectivity was actually higher in the brains of autistic individuals. http://medicalxpress.com/news/2013-01-impaired-brain-autism-involves-local.html Autism spectrum disorders Mon, 14 Jan 2013 15:00:05 EST news277380669 Amid increasing fear of overexposure to radiation from CT scans, a panel of experts has recommended more research on the health effects of medical imaging and ways to reduce unnecessary CT tests, as well as industry standardization of CT machines. http://medicalxpress.com/news/2012-11-experts-closer-scrutiny-exposure-ct.html Cancer Wed, 28 Nov 2012 14:44:31 EST news273336262 New combinations of medical imaging technologies hold promise for improved early disease screening, cancer staging, therapeutic assessment, and other aspects of personalized medicine, according to Ge Wang, director of Virginia Tech's Center for Biomedical Imaging, in a recent paper that appeared in the refereed journal PLOS ONE. http://medicalxpress.com/news/2012-11-scanning-personalized-medicine.html Medical research Mon, 26 Nov 2012 11:52:48 EST news273153158 Video gamers are generally the biggest consumers of computer graphics cards, using the devices to boost the speed and resolution of their digital quests to fend off invading extraterrestrials or outwit hostile dragons. But researchers at Rensselaer Polytechnic Institute seek to harness the power of these computer graphics cards to solve one of the world's most pressing health care technology challenges: radiation exposure from X-ray and CT imaging scans. http://medicalxpress.com/news/2012-09-video-cards-effective-inexpensive-supercomputing.html Medical research Tue, 25 Sep 2012 08:39:59 EST news267781190 Latinos are more likely to store fat in the pancreas and are less able to compensate by excreting additional insulin, a Cedars-Sinai study shows. http://medicalxpress.com/news/2012-09-latinos-vulnerable-fatty-pancreas-diabetes.html Diabetes Tue, 11 Sep 2012 11:17:49 EST news266581039 Researchers funded by the National Institutes of Health have developed a new silk-based stabilizer that, in the laboratory, kept some vaccines and antibiotics stable up to temperatures of 140 degrees Fahrenheit. This provides a new avenue toward eliminating the need to keep some vaccines and antibiotics refrigerated, which could save billions of dollars every year and increase accessibility to third world populations. http://medicalxpress.com/news/2012-07-vaccine-antibiotics-stabilized-refrigeration.html Medical research Mon, 09 Jul 2012 15:00:01 EST news261064225 Concern about overexposure to radiation due to excessive use of medical imaging has come to the fore in recent years.

The RSNA Image Share network was demonstrated today at the annual meeting of the Radiological Society of North America (RSNA). By facilitating access to imaging exams for patients and physicians, the network potentially reduces unnecessary examinations, minimizes patient radiation exposure and enables better informed medical decisions. http://medicalxpress.com/news/2011-11-technology-patients-medical-image.html Other Tue, 29 Nov 2011 01:57:45 EST news241754233 The positive effects of mindfulness meditation on pain and working memory may result from an improved ability to regulate a crucial brain wave called the alpha rhythm. This rhythm is thought to "turn down the volume" on distracting information, which suggests that a key value of meditation may be helping the brain deal with an often-overstimulating world. Researchers from Massachusetts General Hospital (MGH), Harvard Medical School and the Massachusetts Institute of Technology report that modulation of the alpha rhythm in response to attention-directing cues was faster and significantly more enhanced among study participants who completed an eight-week mindfulness meditation program than in a control group. The report will appear in the journal Brain Research Bulletin and has been released online. http://medicalxpress.com/news/2011-04-meditation-brain-volume-distractions.html Neuroscience Thu, 21 Apr 2011 12:56:17 EST news222609361
