PTSD And The Limbic System

PTSD and the Limbic System. Limbic System- A complex system of nerves and networks in the brain, involving several areas near the edge of the cortex concerned with instinct and mood. It controls the basic emotions (fear, pleasure, anger). This nerve system structure is located on both sides of the Thalamus. 'Emotional Life' is housed in the Limbic System, and it has a great deal to do with memory formation.

PTSD and the Amygdala- 'Fight or Flight' reaction is generated in this part of the brain. Physiological responses: increased heart rate, blood flow, muscle tension, muscle tremors. The Amygdala is 'wired differently' in PTSD sufferers. The Amygdala responds to severe trauma with an un-erasable fear response.

PTSD and the Hippocampus- Hippocampus is the 'memory gateway' new memories pass through before permanent storage in the brain. Hippocampus produces Cortisol in an increased fashion in those who experience severe trauma...often leading to physiological changes in brain tissue...atrophy...in that part of the brain.

PTSD and the Hypothalamus- This part of the human brain produces hormones that control body temperature, hunger, moods, sex drive, sleep, thirst and the release of other hormones especially the Pituitary Gland. Every bodily function mentioned is directly affected by severe trauma.

PTSD and the Prefrontal Cortex- This part of the brain controls cognition, personality, decision making, as well as the orchestration of thoughts/actions in accordance with internal goals and appropriate social behavior. Need I explain how PTSD severely alters the aforementioned characteristics of the Prefrontal Cortex?
