Brain Lobes Have you ever wondered how your brain works? How do you remember what ice cream tastes like? How do you know how to walk, or swim, or ride a bike? How do you remember what a firetruck sounds like? Or how to spell your name? You’re in luck because today we’re going to take a trip to planet brain!

Our first stop is the squishy stuff that looks really pink and mushy. It’s called the cerebral cortex. This part of the brain has a lot of jobs to do. Walking, talking, eating, sleeping are just a few of its tasks. These tasks are all divided into sections called the lobes, and they work together like a team. Ready for our next stop? Off to the frontal lobe we go!

The frontal lobe is where we make choices. For example, we can decide if we want grapes or chips. We can decide where to play, what to paint, or what music to listen to. Can you guess where this lobe is located? It’s behind your forehead at the front of your brain! The frontal lobe contains the motor cortex. It is in charge of how we move. Every jump, skip, spin, and leap comes from the nerves in the cortex.

Speaking of moving, let’s hop on down to our temporal lobe. This part of the brain is all about what you hear! This includes listening to music and the sounds you make when you speak. Sound from our ears gets translated here. It's also where we can form what we want to say. This is also the lobe where we can learn to write. On the left hand side of the lobe is a place called Wernicke’s area. It is the area of the brain that helps you learn to spell your name.

Next stop is the parietal lobe. This lobe controls what we taste, smell, and touch. Thanks to this lobe we can like gooey mac and cheese or feel pain from paper cuts. Like the motor cortex, it has a twin known as the sensory cortex. Not surprisingly, the sensory cortex is all about skin sensitivity!

Last stop on this amazing trip is the occipital lobe. It is the vision center of planet brain! This is what helps us see movies, know the faces of friends and family, and view the world around us. Located in the back of the brain, like the projector at the theater, the occipital lobe gets information from the eyes to make the images that we see! Did you know it is also responsible for what we see in our dreams? It also helps us recognize colors and understand how far away something is.

Congratulations! You’ve explored planet brain and figured out how your brain works. Now you know what makes you smile, and laugh, and play all day! See you next time on our trip to planet brain.
