At Healthy Within, we believe that understanding your brain is the first step to healing. Whether you’re facing anxiety, ADHD, trauma, or emotional overload, understanding how your brain functions can help you interpret your symptoms and guide your recovery.


A favorite tool we use to explain the brain to patients, parents, and children is the Hand Model of the Brain, created by Dr. Daniel Siegel, a well-known psychiatrist and neuroscientist. This straightforward, science-based model uses your hand as a visual tool to illustrate the main parts of your brain and their interactions (or occasional disconnections).


The Brain in Your Hand: A Visual Guide


This interactive model uses the parts of your hand to represent five key areas of your brain. It’s intuitive, memorable, and incredibly useful in therapy and education.


1. The Prefrontal Cortex — Fingertips Folded Over


Often called the “CEO of the brain,” the prefrontal cortex (PFC) is responsible for your highest-level thinking. It controls decision-making, empathy, attention, impulse control, and planning. When this area is functioning well, you can think before reacting, regulate your emotions, and connect meaningfully with others.


🧠 In children and adults with ADHD or trauma histories, the PFC may be underactive or overwhelmed, leading to impulsivity, emotional reactivity, or disorganization.


2. The Cerebral Cortex — Back of the Hand


This “thinking cap” processes information from your senses and supports reasoning, movement, and language. It’s the outermost layer of your brain and is essential for conscious awareness.


🧠 When this area is overloaded (like during a panic attack), it may shut down, making it hard to think clearly or speak.


3. The Limbic System — Thumb Curled Inside


Fold your thumb into your palm. This represents your limbic system, the emotional center of your brain. It includes the amygdala, which processes fear and detects threats, and the hippocampus, which helps store emotional memories.


🧠 If you’ve experienced trauma, this part of your brain may be hyperactive, leading to intense emotional reactions, flashbacks, or anxiety.


4. The Brain Stem — Base of the Palm


This is your survival center. The brain stem controls basic life functions like breathing, heart rate, and sleep. It also initiates the fight, flight, or freeze response when danger is sensed.

🧠 When the brain stem is on high alert for too long (as in chronic stress or PTSD), you might struggle with panic, poor sleep, or physical tension.


5. The Spinal Cord — Wrist


Your spinal cord acts like the brain’s messaging system, sending signals to and from your body. It’s responsible for automatic reactions, like pulling your hand away from danger.


🧠 Trauma can cause this system to become overreactive, leading to exaggerated startle responses or physical symptoms like muscle tightness.


Why the Hand Model Works So Well?


At Healthy Within, our neurofeedback specialists and therapists use this model with clients of all ages. It simplifies complex neuroscience, making it easier to understand what’s happening inside the brain, especially during moments of emotional dysregulation.


We use it to help: teens understand their emotional outbursts; parents learn how to respond supportively; adults make sense of their anxiety or trauma triggers; and clients visualize how neurofeedback retrains and calms the brain. The model also helps explain what happens during a “flip the lid” moment—when your brain's emotional center hijacks your thinking brain and you act before you can reason. Understanding this makes it easier to build self-awareness and emotional resilience.


Empowerment Through Understanding


When you can visualize your brain’s inner workings, healing feels less mysterious and more achievable. That’s why education is a key part of everything we do at Healthy Within. Whether we’re offering brain mapping, neurofeedback, psychotherapy, or holistic care, our goal is to help you reconnect with your brain, your body, and your sense of self.
