          Why PTSD Patients Relive Highly Charged Fear Memories in Sleep

          In people with PTSD, during REM sleep norepinephrine and serotonin levels remain high, reducing the brain's ability to inhibit fear-expression neurons through neural rhythms sent between the prefrontal cortex and amygdala. Those with PTSD require higher frequency rhythms to extinguish fear memories. Researchers say unlocking the higher frequencies via therapies could help to restore quality sleep in those with PTSD.

          Protective Factor Against Psychological Trauma Discovered

          The NTRK2 gene has been implicated in resilience to developing PTSD following psychologically traumatic events. Previous studies outlined the role NTRK2 plays in memory formation. Those with increased regulation of the gene developed fewer traumatic memories following traumatic experiences.

          What stress does to the brain

          A new study sheds light on how the brain changes as a result of chronic stress. Selective noradrenaline release rewires connectivity patterns between different brain regions. Activity in the amygdala and networks that process sensory stimuli increased.
