Service members suffering from moral injury are feeling profound guilt and shame for things they may have done—or not done—in combat, or for events they may have witnessed. http://medicalxpress.com/news/2013-03-moral-injury-issues-combat-veterans.html Psychology & Psychiatry Fri, 08 Mar 2013 08:50:01 EST news281953420 Psychologists at the University of Amsterdam (UvA) have discovered that changes in patterns of brain activity during fearful experiences predict whether a long-term fear memory is formed. The research results have recently been published in the prestigious scientific journal Nature Neuroscience. http://medicalxpress.com/news/2013-03-patterns-brain-memory-formation.html Neuroscience Mon, 04 Mar 2013 07:17:00 EST news281603810 Fear responses can only be erased when people learn something new while retrieving the fear memory. This is the conclusion of a study conducted by scientists from the University of Amsterdam (UvA) and published in the leading journal Science. http://medicalxpress.com/news/2013-02-memory-susceptible-eradication-responses.html Psychology & Psychiatry Mon, 18 Feb 2013 16:30:04 EST news280427069 A rustle of undergrowth in the outback: it's a sound that might make an animal or person stop sharply and be still, in the anticipation of a predator. That "freezing" is part of the fear response, a reaction to a stimulus in the environment and part of the brain's determination of whether to be afraid of it. http://medicalxpress.com/news/2013-01-neuroscientists-memory-amygdala.html Neuroscience Mon, 28 Jan 2013 09:31:31 EST news278587877 (Medical Xpress)—Women exposed to trauma may be at greater risk of developing post-traumatic stress disorder because of a heightened fear response, according to a new study. http://medicalxpress.com/news/2012-11-gender-differences-ptsd-due-heightened.html Psychology & Psychiatry Tue, 20 Nov 2012 05:49:38 EST news272612968 (Medical Xpress)—Researchers at Stanford University have developed a procedure that reduces a fear response in mice. It involves, team lead Asya Rolls said as she presented the groups' findings at this year's meeting of the Society for Neuroscience, injecting a protein synthesis inhibitor into the brain and then exposing the mice to a fear trigger while they sleep. http://medicalxpress.com/news/2012-10-procedure-response-mice.html Neuroscience Fri, 19 Oct 2012 07:03:53 EST news269849016 A brain pathway that is stimulated by traumatic or fearful experiences can be disrupted by two compounds that show promise for preventing post-traumatic stress disorder, Indiana University researchers reported. http://medicalxpress.com/news/2012-10-scientists-compounds-thwart-post-traumatic-stress.html Psychology & Psychiatry Mon, 15 Oct 2012 16:00:14 EST news269513137 A new study by Weill Cornell Medical College researchers shows that adolescents' reactions to threat remain high even when the danger is no longer present. According to researchers, once a teenager's brain is triggered by a threat, the ability to suppress an emotional response to the threat is diminished which may explain the peak in anxiety and stress-related disorders during this developmental period. http://medicalxpress.com/news/2012-09-difficult-teens.html Psychology & Psychiatry Thu, 27 Sep 2012 13:28:59 EST news267971302 Fear conditioning using sound and taste aversion, as applied to mice, have revealed interesting information on the basis of memory allocation. http://medicalxpress.com/news/2012-06-neurological-basis-memory.html Neuroscience Mon, 18 Jun 2012 13:25:16 EST news259244323 A single brief therapy session for adults with a lifelong debilitating spider phobia resulted in lasting changes to the brain's response to fear. http://medicalxpress.com/news/2012-05-people-spider-phobia-tarantulas-brain.html Psychology & Psychiatry Mon, 21 May 2012 15:00:48 EST news256813279 (Medical Xpress) -- Neuroscientists at UQ's Queensland Brain Institute have discovered a previously unrecognized layer of gene regulation associated with fear extinction. http://medicalxpress.com/news/2011-08-formation-extinction-memory.html Neuroscience Mon, 15 Aug 2011 08:56:43 EST news232617359 People with dementia may soon have improved oral hygiene because of a National Institutes of Health $1.4 million, four-year grant to Rita A.
