Part 1: The Triune Brain Model
The brain evolved in layers. While we think of it as one organ, different parts specialize in different tasks. Read the descriptions below and label the corresponding areas on the diagram.
A. Neocortex (The Human Brain)
Responsible for logic, language, and abstract thought. It helps us plan and make rational decisions.
B. Limbic System (The Mammal Brain)
The emotional center. Houses the Amygdala and Hippocampus. Manages memory and "big feelings."
C. Brainstem (The Reptilian Brain)
The survival center. Controls breathing, heart rate, and temperature. It is purely reactive.

Part 2: The Amygdala & Prefrontal Cortex
The Amygdala (The Guard)
The Amygdala scans the environment for danger. When it senses a threat, it "pulls the fire alarm," sending signals to the rest of the body to react instantly .
"React first, think later!"
The PFC (The Professor)
The Prefrontal Cortex is where logical reasoning happens. It evaluates if a threat is real or just a false alarm (like a loud car backfiring).
"Let's look at the facts before we panic."
Analysis: The "Downstairs" Brain Takeover
Imagine you are walking in the woods and see a curved shape in the grass. Before you even realize it's a stick, you jump back. Explain what happened in your brain using the roles of the Amygdala and the Prefrontal Cortex .

Survival Simulation Teacher Guide Simulation Facilitation Guide
Lesson 1: Anatomy of the Survival Brain
Teacher Resource
Objective
To demonstrate how a sudden physiological "alarm" (stress response) impairs complex cognitive processing (Prefrontal Cortex) and shifts focus to survival mechanisms (Amygdala).
Phase 1: The Baseline (The Hook)
Setup:
Ask students to stand and find a partner.
One partner holds their hand out like they are holding a glass; the other partner holds a ruler (or just their hand) 2 inches above.
Without warning, the top partner drops the object. The bottom partner must catch it.
Discussion Prompt:
"Did you have to think about moving your hand, or did it just happen? This is your brainstem and amygdala working together before your cortex can even name the object."
Phase 2: The "Processing Jam" Simulation
Round 1: Baseline Logic
Give students a simple logic puzzle or math problem (e.g., "If you have 15 apples and give 3 to 4 friends, how many are left?"). Record how quickly they answer.
Round 2: The Stress Shift
Introduce a "stressor" (loud rhythmic clapping, a 10-second countdown timer, or a surprise loud noise). While this is happening, give a puzzle of equal difficulty.
Key Insights to Facilitate:
1
The Disconnection: Explain that when the amygdala senses the "alarm" (the loud noise/timer), it sends a signal that inhibits the Prefrontal Cortex. We literally become less smart in the moment of danger.
2
Physiological Spillover: Ask students to check their pulse or breathing. Stress is a whole-body event, not just a thought.
Implementation Notes
Trauma Sensitivity
Be mindful of students with known trauma histories. Avoid physical contact and give a clear "opt-out" option if the loud noises or time pressure feel too intense.
The "Why"
Emphasize that this is a protection mechanism. The brain isn't broken; it's doing its job to keep you safe from a perceived threat.

How Your Brain Chooses to Defend You
Fight • Flight • Freeze • Fawn
Survival is Step One
Your brain’s #1 job isn't to be happy or successful—it's to keep you alive .
Every defense mechanism was designed by evolution to solve a specific problem in the wild.
Active
Overpower or Escape
Passive
Wait or Appease
Active Responses: Fight & Flight
Fight
Defeating the threat through power or aggression.
Modern Signs:
Anger / Irritability
Need to control others
Clenched jaw/fists
Flight
Escaping the threat to find safety elsewhere.
Modern Signs:
Anxiety / Panic
Perfectionism (running from failure)
"Busy-ness" / Inability to sit still
Passive Responses: Freeze & Fawn
Freeze
Becoming still or "numb" when you can't fight or flee.
Modern Signs:
Feeling "stuck" or paralyzed
Zoning out / Dissociation
Procrastination / Hiding
Fawn
Appeasing the threat to prevent conflict.
Modern Signs:
People-pleasing
Lack of boundaries
Over-apologizing
There is no "wrong" response.
Your brain picks the strategy it thinks has the best chance of helping you survive in that specific moment .
Next we will look at how these show up in the animal kingdom vs. your own life.

Lesson 2: Analyzing the Four Fs
Student Name
The Mission
Below are several scenarios describing animal and human behaviors in response to a threat. Identify which of the Four Fs (Fight, Flight, Freeze, Fawn) is being demonstrated and explain the "survival logic" behind it.
Case #1: The Opossum
When an opossum is confronted by a predator like a dog, it may suddenly collapse, its body becoming limp and its breathing slowing to almost nothing. It remains motionless for hours, even if the predator nudges or bites it.
Response Type:
Survival Logic:
Case #2: The Over-Apologizer
Jordan is in a group project. A teammate starts raising their voice and getting angry about the workload. Jordan immediately starts saying "I'm so sorry, it's my fault, let me do your part of the work too. What can I do to make it better?"
Response Type:
Survival Logic:
Case #3: The Gazelle
A gazelle grazing in the savanna hears the snap of a twig 50 yards away. Within a fraction of a second, its heart rate triples, its muscles flood with oxygen, and it leaps away at 60 mph toward the horizon.
Response Type:
Survival Logic:
Case #4: The Defiant Student
Maya feels embarrassed when a teacher corrects her in front of the class. Instead of feeling sad, she feels a surge of heat in her chest, stands up, and shouts, "This class is stupid and you're just picking on me!" before slamming her book shut.
Response Type:
Survival Logic:
Reflective Thinking:
Why might humans use "Fawn" (appeasing) in a modern social situation like a disagreement with a boss or a bully, even though it wasn't a choice for most wild animals?
Defense Response Field Guide Defense Response Field Guide
Quick Reference: The Four Fs
Response Evolutionary Goal Mental State Modern Manifestation Fight To overpower the threat and remove the danger physically. Aggressive, Controlling, Hyper-focused Explosive anger, yelling, clenched muscles, feeling "righteous" or blaming others. Flight To create distance between self and the threat as fast as possible. Anxious, Restless, Panicked Running away from conflict, chronic "busy-ness," perfectionism, or avoidance. Freeze To hide in plain sight or "play dead" when fighting/fleeing isn't an option. Numb, Detached, Paralyzed Zoning out, "brain fog," feeling stuck, sleeping excessively, or dissociation. Fawn To appease the threat or find a "friend" in the predator to survive. Submissive, Eager, Self-Sacrificing People-pleasing, inability to say "no," taking the blame, or ignoring own needs to keep peace.
Survival Logic
Why do we "Flip our Lid"?
When your Amygdala triggers one of these 4 responses, it disconnects the Prefrontal Cortex (your thinking brain). This happens because thinking takes too long. In a survival situation, the body values speed over logic .
Understanding your response is the first step toward regaining control.

Step 1: The Activation
After the teacher-led "High Energy" exercise, sit quietly. Close your eyes and scan your body from head to toe. Don't judge the feelings—just notice them.
Step 2: The Key

Preparation
Ensure students have enough space to stand and move.
Have the "Somatic Mapping Worksheet" ready for immediately after.
Clear the "opt-out" procedure for students with physical limitations or sensory sensitivities.
The Goal
The goal is to safely induce a mild sympathetic nervous system response (arousal) so students can accurately observe their own physical "stress markers" while in a controlled environment.
Part 1: The "High Energy" Hook (3-5 Mins)
Script/Facilitation:
"Everyone, please stand up. We are going to do 60 seconds of high-intensity movement to wake up our survival systems. I want you to run in place, high knees, as fast as you can. On my mark... GO!"
(During the minute, offer encouragement. At the 60-second mark:)
"Stop! Sit down immediately. No talking. Close your eyes if you feel comfortable, or just soften your gaze at the floor. Put your hands on your lap. Do not try to change anything. Just listen to what your body is doing right now."
Part 2: The Somatic Scan (5-7 Mins)
Read slowly, with pauses between instructions:
1. Breath: "Notice your breathing. Is it deep or shallow? Is it coming from your chest or your belly? Don't change it. Just notice."
2. Heart: "Shift your attention to your chest. Can you feel your heartbeat? Where do you feel it most—in your neck, your chest, or maybe your fingertips?"
3. Temperature: "Scan your face and hands. Do they feel hot? Cold? Sweaty? Just notice the temperature."
4. Tension: "Scan your jaw, your shoulders, and your stomach. Are you holding any tightness there? Does it feel like a knot, or a vibration?"
"Now, gently open your eyes. Grab your 'Somatic Map' worksheet and use the next few minutes to color-code exactly what you just felt."
Part 3: The Brain-Body Connection
Connecting the Amygdala
Explain that the physical sensations they felt (pounding heart, fast breath) are the Amygdala ordering the Sympathetic Nervous System to prepare for action. Even though there was no "predator," the body responded as if there was one.
The Purpose of Awareness
Why do we map this? Because if we can recognize the physical signs of stress early, we can use our Prefrontal Cortex to intervene before we "flip our lid."
Neuroplasticity Slides The Plastic Brain
How Experience Shapes Your Biology
What is Neuroplasticity?
Your brain is not a computer chip—it's more like a muscle .
"Neurons that fire together, wire together."
The brain strengthens the pathways you use the most, and weakens the ones you don't.
Plasticity
Malleable • Adaptive • Changing
The "Path Through the Grass" Analogy
1
Walk through a field once, and the grass barely bends.
2
Walk it every day for a year, and you create a permanent, dirt path.
3
Soon, you walk that path automatically , even if you weren't trying to go that way.
Trauma and chronic stress act like a heavy truck driving down the "Survival Path" every single day.
Sensitization: The Super-Sensitive Alarm
Normal Alarm
A smoke detector that goes off when there is an actual fire. It works correctly to keep you safe.
Sensitized Alarm
After chronic stress, the alarm becomes "sensitized." Now it goes off if you just burn a piece of toast or if the room gets a little too warm.
TRIVIAL INPUT = MASSIVE RESPONSE
Practice Makes Permanent
If we practice Survival Brain (Amygdala) everyday, those pathways get thick and fast. Our Thinking Brain (PFC) gets weaker from lack of use.
The Good News:
Plasticity works both ways.
We can "unlearn" survival paths and build "safety" paths.

Part 1: The Grass Analogy
Recall the "Path through the Grass" analogy from the slides. In your own words, explain what happens to a neural pathway (a connection between brain cells) when it is used over and over again for survival.
Part 2: Sensitization Analysis
Sensitization
Becoming MORE responsive to a stimulus.
Example: A student who has been bullied in the past jumps when they hear someone laugh, even if the laugh isn't about them.
Habituation
Becoming LESS responsive to a stimulus.
Example: A student who lives near a train track eventually stops noticing the sound of the train at night.
Case Study Analysis:
Scenario: "The False Alarm"
Alex grew up in a very loud, chaotic home where yelling meant something bad was about to happen. Now, Alex is in a calm classroom. The teacher accidentally drops a stack of books, and Alex falls out of their chair, their heart racing and face turning red. Other students just chuckle and keep working.
Is this Sensitization or Habituation?
Why did Alex's brain react this way?
The "Bottom-Up" Brain
When we are in chronic stress, our brain becomes Bottom-Heavy . The "Survival Brain" (Amygdala/Brainstem) is much stronger and more active than the "Thinking Brain" (Prefrontal Cortex).
Critical Thinking Question:
How can we start to "re-walk" the paths to the Prefrontal Cortex? What are some things we might do to strengthen our "Thinking Brain"?
Acute vs Chronic Slides The Long Game
Acute Response vs. Chronic Systems
1. Acute Stress
Acute stress is short-term . It is an immediate response to a specific event.
"The Alarm goes off, you solve the problem, and the Alarm turns off."
Proportional to the threat.
Body returns to "Baseline" quickly.
Helpful for survival (e.g., slamming the brakes).
2. Chronic Stress
Chronic stress is long-term . It happens when the body stays in survival mode for weeks, months, or years.
"The Alarm gets stuck in the ON position."
Cumulative (adds up over time).
Body forgets how to return to "Baseline."
Harmful to long-term health.
Toxic Stress
Biological Wear & Tear
When cortisol and adrenaline are constantly in your system, they start to damage tissues, weaken the immune system, and shrink the hippocampus (memory center).
Chronic stress turns a survival system into a sensitized system .
Hyper-vigilance (Always scanning)
Sleep disturbance
Memory and Focus issues
