1 Appendix 6 Neurobiology of Trauma

2 Cortex Sensory Thalamus Amygdala Basic Neurobiology of Trauma

3 The “high” road The “low” road FEAR

4 SNAKE? VINE?

5 VINE Phew! Vine

6 SNAKE! Fear

7 SNAKE! Fear

8 No Threat No Danger Pre-Trauma Processing of “ordinary” stimulus

9 Threat!! Danger!! Post-Trauma Processing of “ordinary” stimulus

10 Post-trauma fear network in Amygdala Trauma produces an anatomical change in the brain

11 Post-trauma fear network in Amygdala A landscape of fear-inducing cues

12 Neurobiology of Non-Traumatic Memory Integrated Narrative

13 Neurobiology of Traumatic Memory Hippocampus LTP LTP builds the neural networks that create new memories

14 Neurobiology of Traumatic Memory Hippocampus LTP Trauma interferes with LTP functioning Results in loss & fragmentation of memories
