(Medical Xpress) -- Vanderbilt radiologists are rolling out powerful new imaging techniques that provide clearer pictures of the delicate ebb and flow of blood through brain tissue in patients at risk for stroke. http://medicalxpress.com/news/2012-01-imaging-techniques-valuable-tools.html Cardiology Mon, 23 Jan 2012 07:36:54 EST news246526604 (Medical Xpress) -- At UCLA's Laboratory of Integrative Neuroimaging Technology, researchers use functional MRI brain scans to observe brain signal changes that take place during mental activity. They then employ computerized machine learning (ML) methods to study these patterns and identify the cognitive state — or sometimes the thought process — of human subjects. The technique is called "brain reading" or "brain decoding."   http://medicalxpress.com/news/2011-12-neuroscientists-crucial-advances-brain.html Neuroscience Wed, 21 Dec 2011 06:50:01 EST news243670589 Studies have shown that people who are overweight in middle age are more likely to develop Alzheimer's disease decades later than people at normal weight, yet researchers have also found that people in the earliest stages of Alzheimer's disease are more likely to have a lower body mass index (BMI). A current study examines this relationship between Alzheimer's disease and BMI. http://medicalxpress.com/news/2011-11-people-early-alzheimer-disease-bmi.html Diseases, Conditions, Syndromes Mon, 21 Nov 2011 16:40:39 EST news241116031 IQ, the standard measure of intelligence, can increase or fall significantly during our teenage years, according to research funded by the Wellcome Trust, and these changes are associated with changes to the structure of our brains. The findings may have implications for testing and streaming of children during their school years. http://medicalxpress.com/news/2011-10-iq-fall-significantly-adolescence-brain.html Neuroscience Wed, 19 Oct 2011 13:00:13 EST news238247580 Alzheimer's disease (AD) is a common problem that is becoming progressively burdensome throughout the world. A new supplement to the Journal of Alzheimer's Disease, Imaging the Alzheimer Brain, clearly shows that multiple imaging systems are now available to help understand, diagnose, and treat the disease. http://medicalxpress.com/news/2011-10-advances-brain-imaging-diagnosis-alzheimer.html Diseases, Conditions, Syndromes Tue, 11 Oct 2011 12:59:18 EST news237556746 For some people, the glass is always half full. Even when a football fan's team has lost ten matches in a row, he might still be convinced his team can reverse its run of bad luck. So why, in the face of clear evidence to suggest to the contrary, do some people remain so optimistic about the future? http://medicalxpress.com/news/2011-10-brain-imaging-reveals-optimistic-reality.html Neuroscience Sun, 09 Oct 2011 13:00:26 EST news237381640 Carnegie Mellon University biologists have developed an MRI-based technique that allows researchers to non-invasively follow neural stem cells in vivo. http://medicalxpress.com/news/2011-09-scientists-track-neuronal-stem-cells.html Neuroscience Thu, 29 Sep 2011 11:05:07 EST news236513094 When making decisions based on multiple, interdependent factors, we choose based on how these factors correlate with each other, and not based on an ad hoc rule of thumb or through trial and error as was previously thought, according to research funded by the Wellcome Trust. http://medicalxpress.com/news/2011-09-hedging-brain-decisions-based.html Neuroscience Wed, 21 Sep 2011 13:50:01 EST news235831226 Our memories work better when our brains are prepared to absorb new information, according to a new study by MIT researchers. A team led by Professor John Gabrieli has shown that activity in a specific part of the brain, known as the parahippocampal cortex (PHC), predicts how well people will remember a visual scene. http://medicalxpress.com/news/2011-08-ready-brain-scans.html Neuroscience Fri, 19 Aug 2011 07:20:11 EST news232957194 A leading University of Chicago researcher on empathy is launching a project to understand psychopathy by studying criminals in prisons. http://medicalxpress.com/news/2011-08-neural-basis-psychopathy.html Psychology & Psychiatry Mon, 01 Aug 2011 12:50:04 EST news231417707 Whether we choose to accept or fight it, the fact is that we will all age, but will we do so successfully? Aging successfully has been linked with the "positivity effect", a biased tendency towards and preference for positive, emotionally gratifying experiences.

The study's findings indicate that non-invasive intervention can greatly improve patients' inhibitory control. Conducted by a research team led by Dr Chi-Hung Juan of the Institute of Cognitive Neuroscience, National Central University in Taiwan, the research was sponsored by the National Science Council in Taiwan, the UK Medical Research Council, the Royal Society Wolfson Merit Award, and a Fulbright Award. http://medicalxpress.com/news/2011-06-noninvasive-brain-curb-impulsivity.html Neuroscience Wed, 15 Jun 2011 12:27:51 EST news227359629 An Emory University study suggests that the brain activity of teens, recorded while they are listening to new songs, may help predict the popularity of the songs. http://medicalxpress.com/news/2011-06-teen-brain-song-success.html Neuroscience Mon, 13 Jun 2011 04:58:32 EST news227159616 If a friend or relative won $100 and then offered you a few dollars, would you accept this windfall?
