The human brain is one of the most mysterious and inexplicable things in human biology. Though a lot of research has been done, we still have much more to learn about the lobes of the brain.
Because of how much we’ve yet to uncover, in the future we might be able to access some hidden brain functions. Imagine developing superpowers, like telekinesis and mind reading!
The fact that we lack full knowledge of the brain’s capabilities keeps us from understanding the true potential of the brain. So, until we know more about them, we shouldn’t discount any ideas, no matter how impossible they might sound.
We’re going to explore what we do know about the brain, including the basic function of the lobes of the brain, that are responsible for many important processes in the body.
So, hang tight and let’s begin!
What Are The Six Major Regions Of The Brain?
For a moment, acknowledge and honor all that you are instead of all that you are not.

There are six major regions of the brain and each of them have important functions:
- Cerebrum – The cerebrum’s task is to help keep us conscious and to maintain our basic mental activities and functions.
- Diencephalon – The diencephalon includes two main parts: the thalamus, which is like an antenna for sensuous tasks and the hypothalamus, which allows us to manage our feelings and is responsible for basic individual functions and hormone output.
- Mesencephalon – The mesencephalon helps us hear, see, and controls our basic reflexes.
- Medulla oblongata – This part of the brain transmits sensuous signals to the diencephalon and supports important systems, like the cardiovascular, digestive, and respiratory systems.
- Pons – The pons transmits sensuous signals to the cerebellum and the thalamus and gives the partial support to the same systems as medulla oblongata.
- Cerebellum – The cerebellum is tasked with the coordination of highly structured and complex motor functions.
What Are The Functions Of The Main Regions Of The Brain?
The brain has many functions and is a vital organ in the human body. Think of it as a machine with complex consciousness.
We’ve briefly mentioned the main regions of the brain above. Now let’s dive deeper into the functions of each region.
The cerebrum is the biggest region of the brain. Its task is to maintain the work of the five human senses. It’s split into four regions, called the lobes of the brain, which we will discuss a bit later.
The lobes of the brain allow us to perceive the world, talk, touch, sense, receive, process, and send sensory information.
This region of the brain is responsible for transmitting sensuous signals between all other areas of the brain, while at the same time maintaining the peripheral nervous system and its basic functions.
Essentially it’s the link between the major areas of the brain. It stimulates feelings and memories by linking several layers of the limbic system with other systems.
The mesencephalon, also called the midbrain, is a portion of the central nervous system responsible for our sense of sight and sound.
It’s crucial in maintaining several vital processes, such as sleeping, waking, and wariness. Apart from that, it helps modulate our body temperature.
4. Medulla oblongata
The medulla oblongata is basically the thread that links the spinal cord to the other important parts of the brain.
It regulates the oxygen levels in the body, sends signals to regulate heart rate and blood pressure, and regulates reflexive actions like coughing, vomiting, and swallowing.
Just like the diencephalon, the pons is tasked with transmitting various signals throughout the brain lobes. It serves as the link between the cerebellum and the cerebrum.
As for more complex functions, the pons also relates to the process of sleeping and dreaming.
Another name for the cerebellum is “little brain”. Its main task is to ensure the stability of muscles and some basic activities related to the movement of our body.
If the cerebellum is injured, problems arise with the precision and speed of basic movements.
The cerebellum is one of the smallest parts of the brain, but contains the highest number of neurons. And these neurons are potent when it comes to transmitting signals to other sections of both the brain and body.
What Are The 4 Lobes Of The Brain And Their Functions?
The lobes of the brain are located in the cerebrum region of the brain. There are four lobes, and each is responsible for a set of different functions. Each lobe of the brain is crucial for the human body to be able to function properly.
1. Frontal lobe
The frontal lobe is where some of the more complex actions in the brain take place, such as emotional regulation, higher planning, and problem solving.
Apart from that, the frontal lobe also helps facilitate body movement and memory consolidation. Moreover, the left frontal lobe is in charge of speech production and word comprehension.
2. Parietal lobe
The parietal lobe is responsible for signals of pain perception, sense of touch, and feelings of pressure.
The ability to perceive different sensations played a great role in our evolution. Without the feeling of pain our bodies can’t let us know that we are in dangerous situation. Today, we know about the congenital insensitivity to pain or CIP, a condition when a person can’t feel pain that can be quite dangerous for their wellbeing.
So, as you can see, the proper function of the parietal lobe is quite important.
3. Temporal lobe
The main task of the temporal lobe is to transmit and process signals coming to the primary auditory cortex. In other words, it allows us to make a distinction between different types of sounds or languages.
But what does the temporal lobe do that the other lobes of the brain cannot?
It allows us to learn, feel, and remember.
The temporal lobe consists of the left temporal lobe and the right temporal lobe. The primary function of the left temporal lobe is to control the sight and sound processing, while the right side is in charge of visual memory and language comprehension.
4. Occipital lobe
It allows us to distinguish the shapes and range of the objects we see.
These are the main functions of each lobe of the brain. Without any of them, human being is not able to function adequately in the physical world.
Apart from lobes, we should also mention the sensory cortex. The sensory cortex function is to “connect” our senses. The motor cortex is also important, as the primary motor cortex function is to defines the way we move. All of these areas work together with our four lobes to help us interact with our physical environment.
The brain is a powerful organ and we’ve only just begun to unlock its secrets. Perhaps if we can learn to tap into the power of the brain, we will be able to use it to its full capacity.
