Our 5 senses, movement, speech, thought, emotions, memory, and learning are critical to what we do everyday. All these actions are made possible by the amazing cerebrum.
The largest and most highly developed part of our brain is the cerebrum. Without it, you wouldn’t be able to recognize friends, read books, or even play any games. So next time you win a game of hide and seek or tic tac toe, thank your cerebrum!
The Brain Hemispheres
Your cerebrum has a deep groove down the middle that splits it into two parts. We call these two parts the left and right hemispheres. A bridge connects the two hemispheres and allows them to communicate with each other. The left hemisphere deals better with logic and numbers while the right hemisphere deals better with creative tasks.
Even though they are better at certain processes, they still work together. For instance, when you're doing the creative task of drawing, your right hemisphere is going to be more active, but your left hemisphere is still active and helping. Leonardo Da Vinci used both hemispheres when he painted the Mona Lisa, and so do you! Although my drawings aren’t as good. You use all your brain everyday, so don't leave one half at home when going out.
The Brain's 4 Lobes
The cerebrum is split into 4 lobes. Lobes is a fancy way of saying parts. Each lobe has a special function.
Feel the back of your head, that is the occipital lobe and it is responsible for vision.
Touch the top of your head, that is the parietal lobe it lets us feel touch and sensations.
Tap the sides of your head, near your ears. This is the temporal lobe, it is responsible for hearing.
Feel the front of your head, this is the frontal lobe (frontal = at the front) it is responsible for higher level thinking, which means it does a couple of advanced things, such as complex problem solving, planning, decision making, and movement control.
The 4 lobes do a tremendous amount of work yet they are only on the thin outside layer of the cerebrum called the cerebral cortex. The cerebral cortex has the 4 lobes and is equal to the thickness of about a stack of 3 dimes. It is incredible that so much brain processing and action is done in this thin layer.
Congratulations! You now know that the cerebrum is split down the middle into a right and left hemisphere. The hemispheres have 4 lobes, frontal, parietal, occipital and temporal lobes.
