The Brain Explained: A Basic Guide to the Different Parts of the Brain

parts of the brain

Despite some modern supercomputers exceeding the human brain in processing speed and storage, the human brain remains the world’s best “supercomputer.” The human brain is run by a mere 20 watts, while the K-Computer (a Japanese supercomputer) needs 9.9 million watts to operate. And a supercomputer can’t mimic many parts of the brain, like emotion and creativity.

Today we will look at it and understand why it’s the superior supercomputer.

The Three Main Sections of the Brain

Some people may not realize that the brain is more than a pink walnut-shaped thing. The brain has three sections: cerebrum, cerebellum, and brainstem.

The cerebrum is the biggest part of the brain and is divided by the right and left hemispheres. It’s in charge of touch, vision, hearing, and speech. The cerebellum’s role is to regulate muscle movements, posture, and balance.

The brainstem connects the to the brain. It performs many automatic functions (breathing, heart rate, body temperature, amongst other processes).

Parts of the Brain

As previously mentioned, the cerebrum has a left and right side. The corpus callosum transmits messages to both sections of the brain, as the cerebrum’s right and left hemispheres cannot perform the same functions.

The left hemisphere controls speech, comprehension, and writing, while the right hemisphere controls creativity, spatial ability, and artistic skills.

Sections of the Brain

There are four lobes on each of the brain’s hemispheres. Despite each part having specific functions, they all work together. Let’s take a look a the four parts and their function.

The frontal lobe controls behavior, body movement, speech, and intelligence. The parietal lobe controls the sense of touch, interprets vision and hearing, and understands words.

The Occipital lobe allows us to see colors and light. Finally, the temporal lobe controls our memory and organization.

Functions of Certain Parts of the Brain

That’s the overview. Now that we have considered some of the different of the brain, let’s get into further detail about specific areas.

The Prefrontal Cortex

It is in charge of our personality, planning, behaviors, emotion, and short-term memory. People who experience depression, anxiety, and mood disorders may be lacking certain enzymes produced in this area. If that is your case, consider learning about COMT on this site.

The Hippocampus

One of the most critical sections of the brain is the hippocampus, as it’s in charge of our long-term memory. It holds individual memories as well as facts.

The Cerebellum

It is relatively small compared to the cerebrum but ever so important. It stores automatic-learned memories like playing an instrument, tying a shoe, or riding a bike.

The Human Brain Will Always Be The Best Supercomputer

As you have seen, the brain is much more than an organ. With all the put together, it makes even the best supercomputer look inferior. And experts are learning every day about the human brain, so who knows what’s still needs to be understood.
