Your brain is your body's **control center**.
In about 15 minutes, you'll get a **big-picture tour** of: - What the brain is and how it fits into your **nervous system** - The **three major brain regions**: cortex, cerebellum, brainstem - How the brain handles **sensing, thinking, and acting** - What’s true (and what’s myth) about **left brain vs. right brain**
### Quick mental picture Imagine: - A **cauliflower** (the wrinkly top) → that’s your **cortex** - A **little cauliflower stuck at the back, underneath** → that’s your **cerebellum** - A **thick stalk** connecting the brain to your spine → that’s your **brainstem**
