Excerpt:
UNDERSTANDING THE BRAIN AND BODY IN TRAUMA by Dawn McClelland, PHD, and Chris Gilyard, MA
“Several parts of the brain are important in understanding how the brain and body function during trauma.
They include the forebrain (the prefrontal cortex); the limbic system, which is located in the center of the brain; and the brain stem.
When a person experiences a traumatic event, adrenalin rushes through the body and the memory is imprinted into the amygdala, which is part of the limbic system.
The amygdala holds the emotional significance of the event (the intensity and impulse of emotion).
For example, if you’re on a roller coaster, your sensory information is “fear, speed, stress, excitement, not life threatening.”
The amygdala can read the emotional significance of the event: “it’s a ride, it’s fun, you are done in 3 minutes.”
The amygdala stores the visual images of trauma as sensory fragments, which means the trauma memory is not stored like a story, but by how our five senses were experiencing the trauma at the time it was occurring.
The memories are stored through fragments of visual images, smells, sounds, tastes, or touch.

We store them as sensory fragments, no wonder they are confusing and abstract.
It’s our five senses and how they experience trauma that dominates life going forward
Explains a lot

This is a great description of what goes on in the brain.
