The study, published by Cell Press in the June 25 issue of the journal Neuron, uncovers the influence of hypnotic paralysis on brain networks involved in internal representations and self imagery. http://phys.org/news165065163.html Medicine & Health Wed, 24 Jun 2009 12:40:03 EST news165065163 Middle-aged women who had migraine headaches with aura (sensory disturbances, such as with vision, balance or speech) had a higher prevalence of brain lesions when they were older, compared to individuals without similar types of headaches, according to a study in the June 24 issue of JAMA. http://phys.org/news164998675.html Medicine & Health Tue, 23 Jun 2009 23:00:01 EST news164998675 A report in Cancer Research, a journal of the American Association for Cancer Research, highlights a new biomarker that may be useful in identifying patients with recurrent glioblastoma, or brain tumors, who would respond better to anti-vascular endothelial growth factor therapy, specifically cediranib. http://phys.org/news164982427.html Medicine & Health Tue, 23 Jun 2009 13:27:55 EST news164982427 A recent neuroimaging study reveals that the ability to distinguish true from false in our daily lives involves two distinct processes. Previous research relied heavily on the premise that true and false statements are both processed in the left inferior frontal cortex. Carried out by researchers from the Universities of Lisbon and Vita-Salute, Milan, the June Cortex study found that we use two separate processes to determine the subtle distinctions between true and false in our daily lives. Deciding whether a statement is true involves memory; determining one is false relies on reasoning and problem-solving processes. http://phys.org/news164454142.html Medicine & Health Wed, 17 Jun 2009 10:42:44 EST news164454142 A simple magnetic resonance imaging (MRI) test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers at UT Southwestern Medical Center. http://phys.org/news163262140.html Medicine & Health Wed, 03 Jun 2009 15:39:31 EST news163262140 A University of Toronto study provides the first direct evidence that our mood literally changes the way our visual system filters our perceptual experience suggesting that seeing the world through rose-coloured glasses is more biological reality than metaphor. http://phys.org/news163244296.html Medicine & Health Wed, 03 Jun 2009 10:38:59 EST news163244296 The same techniques used to detect suspicious activity in airports, stadiums and other public places are now being used by the UCF researcher who invented them to find and measure potentially life-threatening brain tumors. http://phys.org/news163163282.html Medicine & Health Tue, 02 Jun 2009 12:08:30 EST news163163282 (PhysOrg.com) -- When a crime has been committed, the usual modus operandi for police detectives and their fictional counterparts has been to dust the scene for fingerprints. And once they have a suspect in custody, out comes the polygraph, or lie detector. http://phys.org/news163156190.html Medicine & Health Tue, 02 Jun 2009 10:10:10 EST news163156190 Portions of the brain that activate when people view pictures of objects compared to scrambled images can also be activated by touch alone, confirms a new report published online on May 28th in Current Biology. http://phys.org/news162744208.html Medicine & Health Thu, 28 May 2009 15:44:06 EST news162744208 A new study demonstrates that when faced with a difficult decision, the human brain calls upon multiple neural systems that code for different sorts of behaviors and strategies. The research, published by Cell Press in the May 28th issue of the journal Neuron, provides intriguing insight into the mechanisms that help the human brain rise to the formidable challenge of adaptive decision making in the real world. http://phys.org/news162647119.html Medicine & Health Wed, 27 May 2009 12:45:37 EST news162647119 Cambridge University researchers have discovered that whether someone is a 'people-person' may depend on the structure of their brain: the greater the concentration of brain tissue in certain parts of the brain, the more likely they are to be a warm, sentimental person. http://phys.org/news162017277.html Medicine & Health Wed, 20 May 2009 06:05:28 EST news162017277 The injection of bone marrow cells into the heart of patients with chronic myocardial ischemia (reduced blood flow to some areas of the heart) was associated with modest improvements in blood flow and function of the left ventricle, according to a study in the May 20 issue of JAMA. http://phys.org/news161975077.html Medicine & Health Tue, 19 May 2009 18:12:05 EST news161975077 The carnivorous reptiles (Varanus komodoensis) are known to bite prey and release them, leaving them to bleed to death from their wounds: the victims are reported to go into shock before the dragons kill and eat them. http://phys.org/news161885734.html Biology Mon, 18 May 2009 17:16:10 EST news161885734 By observing the pattern of activity in the brain, scientists have discovered they can "read" whether a person just heard words spoken in anger, joy, relief, or sadness. The discovery, reported online on May 14th in Current Biology, a Cell Press publication, is the first to show that emotional information is represented by distinct spatial signatures in the brain that can be generalized across speakers. http://phys.org/news161528185.html Medicine & Health Thu, 14 May 2009 13:57:01 EST news161528185 Alcohol-use disorders (AUDs) can damage the brain, particularly the frontal and parietal cortices, although this damage is at least partially reversible with sustained abstinence from alcohol. Chronic smoking is extremely common among individuals with AUDs. A new study has used longitudinal magnetic resonance imaging (MRI) of brain blood flow to show that smoking makes it harder for brain blood flow to recover from long-term heavy drinking. http://phys.org/news161278978.html Medicine & Health Mon, 11 May 2009 16:43:14 EST news161278978 The responses of older adults who are asked whether they had a stroke frequently do not agree with diagnoses obtained by magnetic resonance imaging (MRI) of the brain, according to a report posted online today that will appear in the July print issue of Archives of Neurology. http://phys.org/news161278599.html Medicine & Health Mon, 11 May 2009 16:37:12 EST news161278599 Toddlers with autism appear more likely to have an enlarged amygdala, a brain area associated with numerous functions, including the processing of faces and emotion, according to a report in the May issue of Archives of General Psychiatry, one of the JAMA/Archives journals. In addition, this brain abnormality appears to be associated with the ability to share attention with others, a fundamental ability thought to predict later social and language function in children with autism. http://phys.org/news160675501.html Medicine & Health Mon, 04 May 2009 17:05:24 EST news160675501 Donald O'Rourke, MD, Associate Professor of Neurosurgery at the University of Pennsylvania School of Medicine and colleagues, were able to accurately predict the specific genetic mutation that caused brain cancer in a group of patients studied using magnetic resonance imaging (MRI).

The results may support the idea that the brain's memory function may gradually wear itself out in those who go on to develop Alzheimer's. http://phys.org/news158258795.html Medicine & Health Mon, 06 Apr 2009 17:49:45 EST news158258795 Where different ethnic groups store fat in their bodies may account for differences in the likelihood they'll develop insulin resistance and non-alcoholic fatty liver disease, researchers at UT Southwestern Medical Center have found. http://phys.org/news157352386.html Medicine & Health Fri, 27 Mar 2009 06:00:48 EST news157352386 (PhysOrg.com) -- Magnetic resonance imaging (MRI) can serve as a very sensitive technique for detecting small tumors in the body, but it is not as good at identifying the edges of a tumor. Photoacoustic imaging tomography (PAT) is not as sensitive as MRI, but it excels at pinpointing the location of subsurface tissue structures, presumably including the edges of tumors. To take advantage of the best of both of these imaging techniques, a team of investigators led by Fanqing Frank Chen, Ph.D., University of California, San Francisco, has developed a “nanowonton” of cobalt and gold to create an imaging contrast agent for use with both MRI and PAT. http://phys.org/news157309129.html Nanotechnology Thu, 26 Mar 2009 17:59:44 EST news157309129 Duke University chemists are using modified magnetic resonance imaging to see molecular changes inside people's bodies that could signal health problems such as cancer. http://phys.org/news157297184.html Chemistry Thu, 26 Mar 2009 14:40:18 EST news157297184 A new technology which dramatically improves the sensitivity of Magnetic Resonance techniques including those used in hospital scanners and chemistry laboratories has been developed by scientists at the University of York. http://phys.org/news157296235.html Medicine & Health Thu, 26 Mar 2009 14:24:20 EST news157296235
