A mouse study has now spelled out the fundamental mechanisms by which the brain consolidates remote fear memories. The study demonstrates that remote fear memories formed in the distant past are permanently stored in connections between memory neurons in the prefrontal cortex.

Neurologists have revealed changes to a brain mechanism used for learning and survival may play a role in how someone responds to a threat following a traumatic experience. Another study found that another mechanism responsible for emotion and memory is impacted and may make it difficult for someone with PTSD to discriminate between safety, danger, or reward. It overgeneralizes towards danger. These findings could significantly advance future treatments.

A research team has been investigating the underlying mechanisms. The researchers showed that mice lacking a specific serotonin receptor unlearn fear much faster than the wild type. The results of the study provide a viable explanation how drugs that are typically used for the treatment of post-traumatic stress disorder (PTSD) alter our brain activity. The ability to unlearn fear is often impaired in PTSD patients, making it more difficult to carry out therapies.

As a consequence, previously rewarding social targets are now perceived as social threats, which promotes generalized social avoidance and impaired social reward processing that can contribute to psychiatric disorders.

They are considered pathological when they occur frequently (>1 episode per week) and cause daytime fatigue, mood alteration and anxiety. Although Imagery Rehearsal Therapy (IRT) has shown some effectiveness, some patients do not respond to this treatment. A team has now developed a promising new technique combining this classic therapy with the Targeted Memory Reactivation (TMR) method. Thanks to this new therapy, the patients'nightmares decreased significantly and their positive dreams increased.
