    Fear
No Threat




  No Danger



              Pre-Trauma Processing
              of “ordinary” stimulus
Threat!!




  Danger!!



             Post-Trauma Processing
             of “ordinary” stimulus
                      Trauma
                      produces an
                      anatomical
                      change in the

                          Memory
                    LTP builds the
                    neural networks
                    that create new

               Traumatic Memory
                       Trauma interferes
                       with LTP
