(Medical Xpress)—People provided with a real-time readout of activity in specific regions of their brains can learn to control that activity and lessen their anxiety, according to new findings published online in the journal Translational Psychiatry. http://medicalxpress.com/news/2013-05-real-time-brain-feedback-people-anxiety.html Psychology & Psychiatry Thu, 09 May 2013 05:57:12 EST news287297779 Addiction may result from abnormal brain circuitry in the frontal cortex, the part of the brain that controls decision-making. Researchers from the RIKEN Center for Molecular Imaging Science in Japan collaborating with colleagues from the Montreal Neurological Institute of McGill University in Canada report today that the lateral and orbital regions of the frontal cortex interact during the response to a drug-related cue and that aberrant interaction between the two frontal regions may underlie addiction. Their results are published today in the journal Proceedings of the National Academy of Sciences. http://medicalxpress.com/news/2013-01-fmri-uncovers-neural-mechanism-underlying.html Neuroscience Mon, 28 Jan 2013 15:00:12 EST news278590198 Extraversion does not just explain differences between how people act at social events. How extraverted you are may influence how the brain makes choices – specifically whether you choose an immediate or delayed reward, according to a new study. The work is part of a growing body of research on the vital role of understanding personality in society. http://medicalxpress.com/news/2013-01-personality-decision-making-longevity-mental-health.html Psychology & Psychiatry Thu, 17 Jan 2013 17:29:16 EST news277666148 It is well known that violent adults often have a history of childhood psychological trauma. Some of these individuals exhibit very real, physical alterations in a part of the brain called the orbitofrontal cortex. Yet a direct link between such early trauma and neurological changes has been difficult to find, until now. http://medicalxpress.com/news/2013-01-childhood-trauma-brain.html Psychology & Psychiatry Tue, 15 Jan 2013 04:24:20 EST news277446252 An area of the brain called the orbitofrontal cortex is responsible for decisions made on the spur of the moment, but not those made based on prior experience or habit, according to a new basic science study from substance abuse researchers at the University of Maryland School of Medicine and the National Institute on Drug Abuse (NIDA). Scientists had previously believed that the area of the brain was responsible for both types of behavior and decision-making. The distinction is critical to understanding the neurobiology of decision-making, particularly with regard to substance abuse. The study was published online in the journal Science. http://medicalxpress.com/news/2012-11-brain-area-role.html Neuroscience Mon, 26 Nov 2012 13:51:39 EST news273160286 Patients with obsessive-compulsive disorder are characterised by persistent thoughts and repetitive behaviours.
