The Nervous System

In this lesson, you’ll explore your nervous system. It’s the lightning-fast communication system that connects your brain, body, and senses. We’ll start by testing how quickly you can react with a hands-on reaction time challenge. Then we’ll explore how your senses, nerves, and brain work together to send and receive messages in fractions of a second.

You’ll learn how practice can actually rewire your brain (a process called neuroplasticity) to make you faster and more coordinated. You’ll also discover how reflexes protect you from danger before you even realize it. By the end, you’ll understand how every thought, movement, and reaction is powered by your nervous system.

What you’ll learn:

• How your brain, nerves, and senses communicate to control your body
• What reaction time is and how to measure it
• How practice changes your brain and improves your speed
