So does a bigger brain make you smarter? Let's start with understanding the different parts of the brain. There are three major parts in our brain, the cerebrum, the cerebellum, and the brain stem. The cerebrum is the biggest and it is the most known ,because it has the twisted mass of grey matter. It also is very complicated because it it is divided into 2 halves which are called hemispheres. There are different areas or lobes which are parts of the brain in the cerebrum, for example the frontal lobe where your planning and action planning happen. Hemispheres are what make a left and a right side of the brain and different things happen in different hemispheres, for example in the in the left one is where you learn a language and do math. The right hemisphere is where your creativity is. Under the cerebrum is the limbic system and that is where your feelings are controlled. Inside the limbic system is the thalamus which passes Information from your body to the right place in your brain. There is also the hypothalamus in the limbic system which controls your body temperature and food intake, and so without the hypothalamus you will never feel full. Below the the cerebrum is the cerebellum which is what coordinates your bodies movements. Then the last part is the brain stem which monitors all the little functions your body makes like your heart beat, breathing, and blood pressure.
Researchers from Wonderopolis stated “This all makes sense when you consider the importance of the brain to human life. Even though the brain only makes up 3-5% of the body's weight, it uses up an incredible 20% of the body's resources in terms of oxygen and glucose.” This quote explains that even though the brain is small
According to Brain Pop “ The more you know about the brain the easier it gets to compare intelligence” This quote is explaining how it is easier to learn why other People are animals are smarter than each other.
