Anorexia nervosa and bulimia nervosa—disorders characterized by extreme eating behavior and distorted body image—are among the deadliest of psychiatric disorders, with few proven effective treatments. http://medicalxpress.com/news/2013-06-neural-circuitry-anorexia-bulimia.html Psychology & Psychiatry Tue, 04 Jun 2013 00:20:01 EST news289502181 When children with conduct problems see images of others in pain, key parts of their brains don't react in the way they do in most people. This pattern of reduced brain activity upon witnessing pain may serve as a neurobiological risk factor for later adult psychopathy, say researchers who report their findings in the Cell Press journal Current Biology on May 2. http://medicalxpress.com/news/2013-05-kids-brains-under-react-painful-images.html Psychology & Psychiatry Thu, 02 May 2013 12:00:06 EST news286714692 (HealthDay)—Scientists have long thought that stress plays a role in epileptic seizures, and new evidence suggests that epilepsy patients who believe this is the case experience a different brain response when faced with a nerve-wracking situation. http://medicalxpress.com/news/2012-12-link-stress-epileptic-seizures.html Neuroscience Tue, 04 Dec 2012 12:40:02 EST news273845725 (Phys.org)—Scientists have revealed the minutely detailed pain map of the hand that is contained within our brains, shedding light on how the brain makes us feel discomfort and potentially increasing our understanding of the processes involved in chronic pain.  http://medicalxpress.com/news/2012-11-pain-human-brain.html Neuroscience Thu, 29 Nov 2012 08:30:04 EST news273399044 New research at the University of Adelaide has demonstrated that teenagers born prematurely may suffer brain development problems that directly affect their memory and learning abilities. http://medicalxpress.com/news/2012-11-teenagers-brains-affected-preterm-birth.html Neuroscience Tue, 13 Nov 2012 17:00:18 EST news272046233 Life is about failure as much as it is about success. From the mistakes we make at work or school to our blunders in romantic relationships, we are constantly reminded of how we could be better. By focusing on the important qualities that make us who we are – a process called self-affirmation – we preserve our self-worth in the face of our shortcomings. http://medicalxpress.com/news/2012-10-self-affirmation-receptive.html Psychology & Psychiatry Wed, 24 Oct 2012 15:20:45 EST news270310672 (Medical Xpress)—Heightened activity between the emotional and auditory parts of the brain explains why the sound of chalk on a blackboard or a knife on a bottle is so unpleasant. http://medicalxpress.com/news/2012-10-interaction-auditory-cortex-amygdala-responsible.html Neuroscience Wed, 10 Oct 2012 08:11:58 EST news269075512 Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes. http://medicalxpress.com/news/2012-09-genetics-addictions-genes-brain-reaction.html Genetics Tue, 11 Sep 2012 12:56:18 EST news266586971 Snack consumption and BMI are linked to both brain activity and self-control, new research has found. http://medicalxpress.com/news/2012-07-snacking-bmi-linked-effect-brain.html Neuroscience Mon, 23 Jul 2012 10:28:58 EST news262258133 Impaired social function is a cardinal symptom of autism spectrum disorders (ASDs). One of the brain circuits that enable us to relate to other people is the "mirror neuron" system. This brain circuit is activated when we watch other people, and allows our brains to represent the actions of others, influencing our ability to learn new tasks and to understand the intentions and experiences of other people. http://medicalxpress.com/news/2012-03-mirror-brain-autism.html Autism spectrum disorders Fri, 02 Mar 2012 12:06:37 EST news249912274 A low level of response (LR) to alcohol is a genetically influenced characteristic, or phenotype, that reflects at least in part a low brain response to alcohol, and carries significant risk for the later development of alcoholism. This study addressed the physiological underpinnings of a low and high LR, finding significant differences in brain activation during a cognitive task, possibly reflecting differences in the amount of brain activity used to deal with a cognitive challenge. http://medicalxpress.com/news/2011-10-genetically-responses-alcohol-affect-brain.html Medical research Fri, 14 Oct 2011 16:30:15 EST news237828606 How the brain controls impulsive behavior may be significantly different than psychologists have thought for the last 40 years. http://medicalxpress.com/news/2011-08-insight-impulse.html Neuroscience Tue, 30 Aug 2011 17:44:52 EST news233945073 Bulimia nervosa is a severe eating disorder associated with episodic binge eating followed by extreme behaviors to avoid weight gain such as self-induced vomiting, use of laxatives or excessive exercise. It is poorly understood how brain function may be involved in bulimia. http://medicalxpress.com/news/2011-07-brain-disorders-impact-function.html Psychology & Psychiatry Mon, 11 Jul 2011 14:40:57 EST news229614015 Scientists have known for years that playing violent video games causes players to become more aggressive. The findings of a new University of Missouri (MU) study provide one explanation for why this occurs: the brains of violent video game players become less responsive to violence, and this diminished brain response predicts an increase in aggression. http://medicalxpress.com/news/2011-05-violent-video-games-brain-response.html Psychology & Psychiatry Wed, 25 May 2011 14:30:39 EST news225552610
