Understanding Trauma: Learning Brain vs Survival Brain

 

The human brain has two distinct modes of functioning. The first, the “learning brain,” is the conscious, rational, and analytical part of the brain that is responsible for complex problem solving, logical thought, and abstract reasoning. The second, the “survival brain,” is the unconscious, reactive, and instinctual part of the brain responsible for quick action in response to danger.

When a person is exposed to a traumatic event, the survival brain takes over. This is because the brain perceives the event as a threat to survival and shifts into the survival mode. In this mode, the brain focuses on survival and the person is unable to access the learning brain. The person becomes hyper-vigilant, may experience flashbacks, and become overwhelmed by intense emotions.

Understanding this concept is key to understanding how trauma affects an individual’s ability to heal. It also helps to explain why it is so difficult for someone to process a traumatic event or even talk about it. When the brain is in the survival mode, it is unable to engage in abstract thought or problem-solving.
