The effect of trauma on the brain and how it affects behaviors | John Rigg | TEDxAugusta

TEDx Talks2 minutes read

Reacting in arguments can lead to hurtful actions and reflection later; stress affects behavior by influencing the cortex and subcortical brain, controlling instinctive responses and memory, impacting daily functioning and suggesting holistic solutions over pharmaceuticals for stress management.

Insights

  • Stress plays a critical role in influencing behaviors by impacting both the intelligent brain (cortex) and the primitive animal brain, leading to instinctive reactions and memory issues.
  • The speaker, a neuroscientist and physician, promotes non-pharmaceutical solutions like physical therapy, yoga, and meditation for managing stress-induced symptoms, emphasizing the importance of holistic approaches over medication.

Recent questions

  • How does stress impact human behavior and brain function?

    Stress plays a significant role in influencing human behavior and brain function. It affects two main parts of the brain: the cortex, responsible for personality, decision-making, and sensory processing, and the subcortical brain, controlling basic animal functions and reactions. Stress can lead to overreactions in arguments, memory issues, difficulty concentrating, and interfere with sleep. The primitive animal brain, reacting instinctively to situations, can trigger survival instincts like fight-or-flight responses. Soldiers experiencing hyperactivated fight-or-flight responses in combat zones may struggle to readjust to normal life due to continued hyperactivation of the amygdala. Overall, stress can have a profound impact on behavior and brain function, highlighting the importance of stress management techniques.

  • What are some common stress-induced physical symptoms?

    Common stress-induced physical symptoms include headaches, muscle tension, and difficulty sleeping. Soldiers, in particular, often experience these symptoms due to the high-stress environments they face. These physical symptoms can be manifestations of the body's response to stress and can impact daily functioning. The speaker, a neuroscientist and physician, advocates for holistic solutions to address these symptoms, emphasizing the importance of non-pharmaceutical approaches to stress management. By recognizing and addressing these physical symptoms, individuals can work towards better managing their stress levels and overall well-being.

  • How does the primitive animal brain influence human behavior?

    The primitive animal brain plays a crucial role in influencing human behavior, particularly in triggering basic animal instincts like sexual attraction and survival mechanisms. This part of the brain reacts instinctively to situations, controlling bodily functions without conscious thought. It can lead to overreactions in arguments with loved ones, causing individuals to say hurtful things or break stuff. The primitive brain's hyperarousal from stress hormones can interfere with memory storage and recall, impacting attention and memory. Understanding the influence of the primitive animal brain on behavior can help individuals recognize and manage their reactions in various situations.

  • What are some effective alternatives to medication for stress management?

    Effective alternatives to medication for stress management include physical therapy, stretching programs, relaxation techniques, yoga, meditation, and exercise. These non-pharmaceutical approaches can help individuals cope with stress and its related symptoms in a holistic manner. The speaker, a former professional musician turned doctor, highlights the importance of considering these alternatives for stress management, particularly for soldiers experiencing high levels of stress. By incorporating these techniques into their daily routines, individuals can work towards better managing stress and improving their overall well-being without relying solely on medication.

  • How does stress impact soldiers in combat zones and upon returning home?

    Stress can have a significant impact on soldiers in combat zones and upon returning home. Soldiers experiencing hyperactivated fight-or-flight responses in combat zones may struggle to readjust to normal life due to continued hyperactivation of the amygdala. This can lead to difficulties in memory, concentration, and sleep, impacting their daily functioning. Stress-induced physical symptoms like headaches and muscle tension are common among soldiers, highlighting the need for effective stress management techniques. The speaker, a neuroscientist and physician, emphasizes the importance of holistic solutions over pharmaceuticals to address stress-related issues in soldiers, advocating for approaches like physical therapy, relaxation techniques, and exercise. By recognizing and addressing the impact of stress on soldiers, effective strategies can be implemented to support their well-being and adjustment to civilian life.

Summary

Impact of Stress on Behavior and Memory

  • Overreacting in arguments with loved ones can lead to saying hurtful things and breaking stuff, causing reflection on behavior later.
  • Stress is a significant factor influencing behaviors, affecting the two brains in humans: the cortex (intelligent brain) and the subcortical brain (primitive animal brain).
  • The cortex is where personality, individuality, decision-making, and sensory information processing occur, while the subcortical brain controls basic animal functions and reactions to the environment.
  • The primitive animal brain reacts instinctively to situations, controlling bodily functions like heartbeat, breathing, and digestion without conscious thought.
  • Sexual attraction is a basic animal instinct triggered by the primitive brain, influencing behaviors even in committed individuals.
  • Survival instincts like fight-or-flight are powerful drivers controlled by the primitive animal brain, ensuring quick responses to threats for survival.
  • Soldiers experiencing hyperactivated fight-or-flight responses in combat zones may struggle to readjust to normal life upon returning home due to the amygdala's continued hyperactivation.
  • Sensory information is relayed to both the cortex and the primitive animal brain, with the latter reacting faster to threats due to its evolutionary survival mechanisms.
  • Stress can lead to memory issues and difficulty concentrating as the primitive animal brain's hyperarousal diverts attention from memory storage and recall.
  • Hyperarousal from stress hormones can interfere with sleep, memory, and attention, impacting daily functioning and causing memory problems in individuals.
