This could be an underlying cause of the higher incidence of suicide among women, according to research at the University of Illinois at Chicago. Studying postmortem tissue from brains of psychiatric [...]

With racial segregation declining between neighborhoods, segregation now taking new form http://www.psypost.org/2015/07/with-racial-segregation-declining-between-neighborhoods-segregation-now-taking-new-form-36294 http://www.psypost.org/2015/07/with-racial-segregation-declining-between-neighborhoods-segregation-now-taking-new-form-36294#comments Fri, 31 Jul 2015 00:13:13 +0000 http://www.psypost.org/?p=36294 Recent research has shown that racial segregation in the U.S. is declining between neighborhoods, but a new study indicates that segregation is manifesting itself in other ways — not disappearing. “We just can’t get too excited by recent declines in neighborhood segregation,” said lead author Daniel Lichter, the Ferris Family Professor in the Department of [...]

New ‘VAST’ tool gives neuroscientists previously unachievable brain images at a nanoscale resolution http://www.psypost.org/2015/07/new-vast-tool-gives-neuroscientists-previously-unachievable-brain-images-at-a-nanoscale-resolution-36291 http://www.psypost.org/2015/07/new-vast-tool-gives-neuroscientists-previously-unachievable-brain-images-at-a-nanoscale-resolution-36291#comments Fri, 31 Jul 2015 00:08:10 +0000 http://www.psypost.org/?p=36291 A new imaging tool developed by Boston scientists could do for the brain what the telescope did for space exploration. In the first demonstration of how the technology works, published July 30 in the journal Cell, the researchers look inside the brain of an adult mouse at a scale previously unachievable, generating images at a [...]

These thoughts not only distract from other activities but also fail to resolve the underlying life issues. Further, the ideas that receive focused attention in these depressive ruminations are frequently quite distorted and lead to distress. The [...]

Computerized treatment may combat PTSD symptoms http://www.psypost.org/2015/07/computerized-treatment-may-combat-ptsd-symptoms-36287 http://www.psypost.org/2015/07/computerized-treatment-may-combat-ptsd-symptoms-36287#comments Thu, 30 Jul 2015 23:58:15 +0000 http://www.psypost.org/?p=36287 Some 10-15 percent of combat veterans struggle with wounds invisible to the naked eye: post-traumatic stress. Their lives are ridden with debilitating symptoms: insomnia, flashbacks, depression, anxiety, guilt, and ever-present tension. While there is no cure-all for post-traumatic stress disorder (PTSD), cognitive behavioral therapy — which actively reprocesses traumatic events to reduce symptoms — has [...]

But in genetics as in life, parenting is about knowing when your voice needs to be heard, and the best ways of doing so. Typically, compromise reigns, and one copy of each gene is inherited from each parent so that the two contribute [...]

The findings, published July 10 in the Journal of Neurotrauma, could help identify patients who might benefit from extra therapy or experimental treatments. “Compared to other proteins that have been measured in traumatic brain injury, BDNF does [...]

That praise, or other possible reward, improves the performance of children with ADHD on certain cognitive tasks, but until a recent study led by researchers from the [...]

When you are worried about something at work, do you find yourself more exhausted at the end of the day? This phenomenon is a result of the activation of a specific area of the brain when we attempt to participate in [...]
