🧠 Understanding behaviour starts with brain function.
The downstairs brain (think of the brainstem + limbic areas) is the emotional, survival-focused part of the brain. It’s responsible for:
✨ reacting quickly
✨ feeling intense emotions
✨ defending safety (fight/flight/freeze)
✨ instinctive responses
When someone feels overwhelmed, unsafe, or overloaded, the downstairs brain takes the lead - and that’s when logic and reasoning take a back seat.
The upstairs brain (the prefrontal cortex) is the thinking, planning, regulating part. It helps with:
✨ problem-solving
✨ self-control
✨ perspective taking
✨ flexible thinking
Here’s the key:
The upstairs brain doesn’t shut off forever - it just can’t fully show up under stress.
When the downstairs brain is overloaded, reasoning and decision-making become much harder.
So what does this mean in practice?
➡️ You can’t reason with a nervous system that doesn’t feel safe.
➡️ Behaviour isn’t willful misbehaviour, it’s communication from the downstairs brain.
➡️ Regulation comes first; reasoning follows.
This perspective helps us respond with empathy, not frustration - prioritising connection before correction. 🤍
