    Studysummary In this study, researchers found that both direct and witnessed trauma in mice are associated with reduced levels of the neurosteroid allopregnanolone, potentially influencing PTSD outcomes, and that treatment with synthetic neurosteroids may mitigate fear responses linked to observed trauma.
