Left Brain, Right Brain: A Simple Way To Understand How Your Mind Works

Many people have heard the idea that the “left brain” is logical and the “right brain” is emotional and creative. It’s a familiar way of explaining why we think and feel the way we do. But the truth is that the brain is far more complex than just two sides.

There are many different parts of the brain working together all the time. However, the left‑brain/right‑brain idea can still be a helpful way to understand yourself, especially if you find neuroscience confusing or overwhelming.

Think of it as a simple doorway into a much bigger picture.

The Simple Version Most People Know

You may have heard or witnessed one of my whiteboard drawings:

• The Left Side Of The Brain Is Logical, Organised, And Good With Words

• The Right Side Of The Brain Is Emotional, Creative, And Good With Feelings

  
  

This is not completely wrong, but it is not the full story.

You are never using only one side of your brain. Both sides communicate constantly.

But the idea is still useful because it helps explain why you sometimes feel “in your head” and other times feel “in your emotions.”

How I Explain The Brain To Make It Easier To Understand

When I talk about the brain with clients, I often use a very simple explanation: the front brain (the part that helps us think clearly) and the emotional brain (the part that reacts fast when we feel unsafe).

This is not the full scientific picture, the brain is far more complex, with many areas working together, but I use this simplified version because it helps people understand what is happening in their bodies without feeling overwhelmed.

The Front Brain (Prefrontal Cortex) Left

This is the part behind your forehead. It helps you:

• Think Clearly

• Make Decisions

• Stay Regulated

• Communicate Calmly

  
  

The Emotional Brain (Limbic System) Right

This part reacts quickly. It helps you:

• Feel Emotions

• Sense Danger

• Protect Yourself

  
  

What Happens When You Are Triggered/activated

When something feels threatening, even if it is not dangerous now, the emotional brain takes over.

When this happens:

• The Front Brain Switches Off

• The Emotional Brain Switches On

• Thinking Becomes Hard

• Reactions Become Fast

• Everything Feels Bigger

  
  

This is why you might snap, shut down, cry, panic, or misread tone. Your brain has moved into protection mode.

Why I Use This Explanation

I use this simple “front brain / emotional brain” model because:

• It Is Easier To Understand

• It Helps People Make Sense Of Their Reactions

• It Reduces Shame

• It Shows That These Responses Are Biological, Not Personal Failures

• Helps understanding of why they switch between logic and emotion

• Why you can think clearly one moment and feel overwhelmed the next

• Why stress makes it hard to think

• Why trauma affects memory, decision‑making, and reactions

• Why you sometimes feel “split” inside

  
  

It is not the full neuroscience, but it is a helpful way to understand what is happening inside you when you feel overwhelmed or triggered. It gives language to something people feel but cannot always explain.

The More Accurate Version (Explained Simply)

The brain is not two halves fighting each other. It is many systems working together, including:

• The Thinking System (Planning, Problem‑Solving, Logic)

• The Feeling System (Emotions, Connection, Intuition)

• The Survival System (Fight, Flight, Freeze, Fawn)

  
  

These are not literal locations. They are different modes your brain shifts into depending on how safe or overwhelmed you feel.

This is much easier to understand than memorising brain anatomy.

Why This Matters For Everyday Life

When you feel safe, the thinking and feeling systems work together. You can:

• Make Decisions

• Communicate Clearly

• Stay Regulated

• See Things In Perspective

  
  

When you feel stressed, overwhelmed, or triggered, the survival system takes over. You might:

• React Quickly

• Feel Flooded With Emotion

• Shut Down

• Struggle To Think Clearly

• Misread Tone Or Intent

• Go Into People‑Pleasing Or Defensiveness

  
  

This is not you “being dramatic.” It is your nervous system doing its job.

How Neurodiversity Fits Into This

For autistic and ADHD nervous systems, the balance between these modes can be different. For example:

• Sensory Overload Can Push The Survival System Online Quickly

• Emotional Intensity Can Activate The Feeling System Strongly

• Hyperfocus Can Strengthen The Thinking System

• Masking Can Exhaust All Three Systems

• Burnout Can Make The Survival System Dominant

  
  

This is not dysfunction. It is a different neurotype with different wiring.

A Simple Way To Explain It To Yourself

Instead of thinking:

“I’m too emotional.” “I’m too logical.” “I’m overreacting.” “I can’t think straight.”

Try thinking:

“My brain has shifted into a different mode.” “My survival system is trying to protect me.” “My thinking system will come back online when I feel safer.”

This removes shame and adds understanding and awareness.

A Gentle Summary

The left‑brain/right‑brain idea is not literally true, the brain is far more complex. But it is a helpful metaphor for understanding the different ways we think, feel, and respond. You are not broken. You are not “too much.” You are not “irrational.” You are not failing.

You are a human being with a nervous system that shifts between different modes depending on safety, stress, and past experience.
