A new study suggests that bright light therapy may improve sleep, cognition, emotion and brain function following mild traumatic brain injury (TBI). http://medicalxpress.com/news/2013-05-bright-therapy-recovery-patients-mild.html Health Fri, 31 May 2013 11:37:16 EST news289219028 In a study designed to differentiate why some stroke patients recover from aphasia and others do not, investigators have found that a compensatory reorganization of language function to right hemispheric brain regions bodes poorly for language recovery. Patients who recovered from aphasia showed a return to normal left-hemispheric language activation patterns. These results, which may open up new rehabilitation strategies, are available in the current issue of Restorative Neurology and Neuroscience. http://medicalxpress.com/news/2013-04-shift-language-function-hemisphere-impedes.html Neuroscience Thu, 04 Apr 2013 12:46:39 EST news284298392 Why do we spend roughly 10 percent of our waking hours with our eyes closed - blinking far more often than is actually necessary to keep our eyeballs lubricated? Scientists have pried open the answer to this mystery, finding that the human brain uses that tiny moment of shut-eye to power down. http://medicalxpress.com/news/2012-12-brain-rest.html Neuroscience Fri, 28 Dec 2012 07:40:01 EST news275899802 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 Whether we choose to accept or fight it, the fact is that we will all age, but will we do so successfully? Aging successfully has been linked with the "positivity effect", a biased tendency towards and preference for positive, emotionally gratifying experiences. New research published in Biological Psychiatry now explains how and when this effect works in the brain. http://medicalxpress.com/news/2011-07-secret-successful-aging.html Psychology & Psychiatry Thu, 14 Jul 2011 10:00:48 EST news229856357
