Understanding the Primitive Animal Brain: How Stress and Trauma Impact Behavior

🧠The human brain has two parts: the cortex and the subcortical brain. The cortex is responsible for reasoning and decision-making, while the subcortical brain controls our instinctive and survival responses.

🔥Stress and trauma can activate the fight-or-flight response in the subcortical brain, leading to hyperarousal and impulsive behavior. This response is helpful in dangerous situations but can be maladaptive in everyday life.

🏥Soldiers who experience trauma in combat may develop hyperactive fight-or-flight responses, causing them to react to non-threatening situations as if they were dangerous. This can lead to irritability, agitation, and difficulty adjusting to civilian life.

💡Understanding the impact of stress and trauma on the primitive animal brain can help us develop strategies to manage our reactions. Techniques like mindfulness, therapy, and stress reduction activities can help regulate the subcortical brain's response.

😌By recognizing the role of the subcortical brain in our behavior, we can develop empathy for ourselves and others who may be struggling with stress or trauma. Compassion and understanding can go a long way in supporting mental and emotional well-being.

What is the difference between the cortex and the subcortical brain?

—The cortex is the part of the brain responsible for reasoning and decision-making, while the subcortical brain controls our instinctive and survival responses.

How does stress impact our behavior?

—Stress can activate the fight-or-flight response in the subcortical brain, leading to hyperarousal and impulsive behavior. This can cause irritability, agitation, and difficulty concentrating.

What is the fight-or-flight response?

—The fight-or-flight response is a physiological reaction to perceived threats. It prepares the body to either confront the threat (fight) or flee from it (flight). This response is automatic and triggered by the subcortical brain.

How can stress impact soldiers who have experienced trauma in combat?

—Soldiers who have experienced trauma in combat may develop hyperactive fight-or-flight responses, causing them to react to non-threatening situations as if they were dangerous. This can lead to difficulties in adjusting to civilian life and may require therapy and support.

What can we do to manage stress and regulate our reactions?

—There are various strategies to manage stress and regulate our reactions, such as mindfulness, therapy, stress reduction activities, and self-care. These techniques can help calm the subcortical brain's response and promote emotional well-being.

00:00The video discusses the impact of stress and trauma on the primitive animal brain and how it leads to overreactions and impulsive behavior.

05:59The cortex and the subcortical brain are two parts of the human brain, with the cortex responsible for reasoning and decision-making.

10:23The subcortical brain, particularly the amygdala, is hyperactivated by stress, triggering the fight-or-flight response.

12:08Soldiers who experience trauma in combat have a hyperactive fight-or-flight response, leading to overreactions when faced with non-threatening situations.

13:00The animal brain reacts faster than the thinking brain, making it challenging to control impulsive reactions triggered by stress.
