  • Adult brains produce new cells in previously undiscovered area August 15, 2017
    A discovery may lead to new treatments for anxiety, depression and post-traumatic stress disorder (PTSD). Scientists have discovered that new brain cells are produced in the adult amygdala, a region of the brain important for processing emotional memories. Disrupted connections in the amygdala, an ancient part of the brain, are linked to anxiety disorders such […]
  • Being bullied may dramatically affect sleep August 10, 2017
    New research, using a mouse model simulating human bullying, suggests that being bullied produces long-lasting, depression-like sleep dysfunction and other effects on daily biological rhythms.

  • How social rank can trigger vulnerability to stress July 13, 2017
    Rank in social hierarchies has been identified by researchers as a major determining factor for vulnerability to chronic stress. They also show that energy metabolism in the brain is a predictive biomarker for social status as well as stress vulnerability and resilience.
  • Predictive model may help forecast migraine attacks July 12, 2017
    A new model based on measuring stress from daily hassles may help forecast future migraine headache attacks in those who develop them frequently.
  • PTSD may be physical and not only psychological July 11, 2017
