Where Do Fears Come From?

Exposure therapy for fears and phobias may only have a 50% success rate because fear memories outlast competing safety memories learned from therapy. Researchers investigate the genesis of fear memories and have developed a new mathematical model to help strengthen exposure therapies.

Prior Stressful Events Can Help Build Resilience

A display of defensive behaviors, when faced with an aggressive mouse, predicted a smaller mouse's ability to become resilient following a traumatic event. Stimulating dopamine production in defensive smaller mice induced resilience.

How Neurons From PTSD Patients React to Stress

Neurons derived from stem cells of combat veterans with PTSD react differently to stress hormones than those derived from veterans without PTSD. The findings shed new light on how genetics can cause some to develop PTSD following a traumatic event.

Sound Cues During Sleep Could Help People to Forget Specific Memories

Previous research found sound cues played during sleep can improve a person's memory. A new study reports that sound cues during sleep can also help to weaken intrusive and traumatic memories. Researchers say sound cues during sleep could be used to both increase or decrease the ability to recall specific memories.

War-Zone Related Stress May Lead to Changes in the Microstructure of the Brain

War zone-related stress was associated with alterations in limbic gray matter microstructure, independent of a mental health or tbi diagnosis. In turn, these alterations were associated with cognitive function, including impaired response inhibition.

Molecular Changes in the Brain in the Aftermath of a Traumatic Event May Help Explain Long-Term Susceptibility or Resilience

In mice genetically more susceptible to PTSD following a stressful event, researchers found an increased expression of cortisol receptors on neurons in the CA1 region of the dorsal hippocampus. Those increased receptors enabled an elevated expression of the HCN1 protein and TRIP8b, reducing neural excitability.
