Persons with an addictive-like eating behavior appear to have greater neural activity in certain regions of the brain similar to substance dependence, including elevated activation in reward circuitry in response to food cues, according to a report posted online today that will appear in the August print issue of Archives of General Psychiatry. http://phys.org/news221154269.html Medicine & Health Mon, 04 Apr 2011 18:00:04 EST news221154269 Wouldn't life be easy if everything happened as we anticipated? In reality, our brains are able to adapt to the unexpected using an inbuilt network that makes predictions about the world and monitors how those predictions turn out. An area at the front of the brain, called the orbitofrontal cortex, plays a central role and studies have shown that patients with damage to this area confuse memories with reality and continue to anticipate events that are no longer likely to happen. http://phys.org/news215693264.html Medicine & Health Mon, 31 Jan 2011 10:48:10 EST news215693264 University of Pittsburgh researchers have recorded neuron activity in adolescent rat brains that could reveal the biological root of the teenage propensity to consider rewards over consequences and explain why adolescents are more vulnerable to drug addiction, behavioral disorders, and other psychological ills. http://phys.org/news215263889.html Medicine & Health Wed, 26 Jan 2011 12:10:01 EST news215263889 A team of French researchers headed by Jean-Claude Dreher of the Centre de Neuroscience Cognitive in Lyon, France, has provided the first evidence that the orbitofrontal cortex (located in the anterior ventral part of the brain) contains distinct regions that respond to secondary rewards like money as well as more primary gratifications like erotic images. These findings, published in The Journal of Neuroscience, open new perspectives in the understanding of certain pathologies, such as gambling addiction, and the study of the neural networks involved in motivation and learning. http://phys.org/news205144723.html Medicine & Health Fri, 01 Oct 2010 09:39:15 EST news205144723 Chronic and severely stressful situations, like those connected to depression and posttraumatic stress disorder, have been associated with smaller volumes in "stress sensitive" brain regions, such as the cingulate region of the cerebral cortex and the hippocampus, a brain region involved in memory formation. A new study, published by Elsevier in Biological Psychiatry, suggests that chronic insomnia may be another condition associated with reduced cortical volume. http://phys.org/news183808301.html Medicine & Health Wed, 27 Jan 2010 09:53:29 EST news183808301 Professor Declan Murphy and colleagues Dr Michael Craig and Dr Marco Catani from the Institute of Psychiatry at King's College London have found differences in the brain which may provide a biological explanation for psychopathy. The results of their study are outlined in the paper 'Altered connections on the road to psychopathy', published in Molecular Psychiatry. http://phys.org/news168610123.html Medicine & Health Tue, 04 Aug 2009 13:20:02 EST news168610123 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
