Explore the two brains within us - the human brain and the primitive brain - and how hurtful words and broken things affect them. Learn about the cerebral cortex, limbic system, stress response system, and the effects of stress on our physiology and brain development.
E N D
Ever had a argument with a loved one that lead to…*Hurtful Words?*Broken Things?And later reflected on“What just happened?”
The Cerebral Cortex:Thinking/Personality Brain • Evaluates emotions in a more sophisticated manner • Impulse control, planning, organization, personality • Making meaning & choices
The Cerebral Cortex:Thinking/Personality Brain Large in Humans Our Individuality How We Take Action “we rule the world because of our large brains”
The Brain Stem:Primitive/Survival Brain • Controls the rhythms of life: • heartbeat, waking, sleeping, breathing, cyclical release of hormones • Arousal systems • Reaction to threat: • fight, flight or freeze
The Brain Stem:Primitive/Survival Brain As Animals we… Eat, Breathe, Move Make waste prodcts Make babies
Human Brain – in our controlWe think and control urgesPrimitive Brain – out of our controlFast response and urges
The Stress Response SystemVideo 1Video 2 • The alarm reaction • A quick, complex, total body response to a serious threat • The body is mobilized for “fight, flight or freeze”
Physiological Changes Involved in the Alarm Response (Fight or Flight) • Increased heart rate, blood pressure & breathing • Release of glucose + increased muscle tone • Nervous system changes increased focus on the threat and tuning out of everything else • Stress hormones (adrenaline, cortisol) are the messengers that initiate all of the above
The Story of a SoldierThe Basic Instinct to SurviveFight Flight Freeze
When the threat is so overwhelming there is no hope in fighting or fleeing • Freeze – Submission - Collapse • The body prepares to be injured • Heart rate slows, blood moves from extremities to inner organs • The mind detaches from current situation • Natural endorphins are released which decreases perception of anxiety and pain
The Story of a StudentOverwhelmed, can’t think and becomes detached from reality
Physiological Problems Constant High Levels of Stress Hormones • High Blood Pressure • High Glucose Levels (weight gain, diabetes) • Cortisol inhibits anti-inflammatory chemicals to inflammation lead to pain (fibromyalgia) • With high levels of stress hormones (adrenaline, cortisol) the body downgrades the receptors. • Memories are hard to make (hard to learn)
Early Brain Development • Nurturing, responsive, and individualized interactions from birth build healthy brain structure. • Healthy brain architecture is the necessary foundation required for optimal future learning, behavior and health. Regional Child Abuse Prevention Councils 2011
Review of Brain Development Most of Brain Development Occurs in the Early Years
Stress and the Brain • Excessive and repeated stress: • Neglect, violence • Chaos, unpredictability • Hostility, rejection • Causes disruption of brain architecture: • Impairs cell growth • Interferes with healthy neural circuits Regional Child Abuse Prevention Councils 2011
Flashbacks • Trauma memories that have not been verbally integrated and come back in the form of sensory memories that make it feel as if the trauma were occurring again in the here and now.
Trauma TriggersFlashbacks are most often triggered by a non-verbal memory • Sights • Sounds • Smells • Bodily sensations • Emotional reactions • Motor memories

What are ACEs?Adverse Childhood Experiences ACEs are experiences in childhood that are unhappy, unpleasant, hurtful Sometimes referred to as toxic stress or childhood trauma
What are the Adverse Childhood Experiences? • Child physical abuse • Child sexual abuse • Child emotional abuse • Physical Neglect • Emotional Neglect • Mentally ill, depressed or suicidal person in the home
What are the Adverse Childhood Experiences? 7. Drug addicted or alcoholic family member 8. Witnessing domestic violence against the mother 9. Loss of a parent to death or abandonment, including abandonment by divorce 10. Incarceration of any family member
ACEs often last a lifetime . . . but they don’t have to • Healing can occur • Cycle can be broken • Safe, stable, nurturing relationships heal parent and child
ADVERSE CHILDHOOD EXPERIENCEs The Most Powerful Determinate of the Public’s Health Abuse and Neglect • Child physical abuse • Child sexual abuse • Child emotional abuse • Neglect Indicators of Family Dysfunction • Mentally ill, depressed or suicidal person in the home • Drug addicted or alcoholic family member • Witnessing domestic violence against the mother • Parental discord – indicated by divorce, separation, abandonment • Incarceration of any family member ACE Score: the number of categories of adverse childhood experience to which a person was exposed.

Impact of ACEs on Brain Development A PET scan of a normal brain (left) shows a high level of brain activity in the temporal lobes of the brain. The temporal lobes are responsible for regulating emotions and receive input from the senses. The temporal lobes on the right are from a severely traumatize child in which the lobes are inactive. Children with damage to this part of the brain suffer sever emotional and cognitive problems as well as have difficulty in making and/or sustaining positive relationships.
