When Does the Frontal Lobe Fully Develop
When does the frontal lobe fully develop?
Our body is a complex structure that is made for several organs that do different activities. The brain is one of the largest and most vital parts of the human body. The human body functions properly because of the proper functions of the brain.
The brain is connected to different systems of the body like the nervous system, respiratory system, digestive system, reproductive system etc. that does different bodily functions which helps the human body to function every day.
The brain is divided into several lobes, which have different functions. Each of these lobes has different functions, which make the brain a complex organ.
The different lobes that make up the human brain are Frontal lobes, Parietal lobes, temporal lobes, and occipital lobes. Each of these nodes has different and particular functions which help in the proper working of the human body.
Frontal lobe: The Vital Part of the Brain
The Frontal lobe is a vital part of the brain and is the biggest of the different types of lobes. The frontal lobe is almost one-third of the size of the brain; the other lobes combined make up two-thirds of the brain. The frontal lobe is located in the front portion of the head of a human body, under the skull and closer to the forehead.
The frontal lobe is a part of the cerebral cortex. The cerebral cortex is the outer layer of the brain, which is usually gray in color and also has a popular name, gray matter.
The frontal lobe is separated from the parietal lobe by a groove called central sulcus and is separated from the temporal lobe by a much deeper lobe called as the lateral sulcus.
Fully Developed Frontal Lobe
A frontal lobe of the human brain is fully developed only when the person is 25 years old or more. The rational part of the brain of a human isn’t fully developed until they are 25 years of age. Hence, teens and adults, until their mid-twenties, do not have a fully rational brain.
The smartness or intelligence of a person does not mean that they have a fully developed frontal lobe or have a rational thinking capacity. In other words, a smart or intelligent teen or an adult in their early twenties need not be a good decision-maker.
The full maturity of the frontal lobes happens only between the mid-twenties and the late twenties, and this is the thing that marks the cognitive maturity, which is often associated with the adulthood of human beings.
The frontal lobes are the lobes of the brain that are responsible for problem solving and judgment, motor functions, emotional expression, memory, language, and sexual behavior.
The frontal lobe is the part of the brain that acts as the control station for our personality and communication ability. The frontal lobes are the region of the brain that can get injured more often than any other lobes of the brain because of its positioning. The frontal lobe is covered by the frontal cortex and thus, the cortex is like a security cover for the frontal lobe.
The Frontal Lobe, its Different Parts, and Different Functions
The frontal lobe is the biggest and the most vital of the lobes of a brain present in almost all mammals. The size of the frontal lobe may vary with respect to the kind of mammal. One of the popular facts about a brain is that the two sides of the brain control the functions of the opposite sides of the body and this is good for the frontal lobes as well.
That is, the left frontal lobe controls the functions of the right side of the body and the right frontal lobe controls the left side of the body. The brain is the only organ that is very complex in the human body. This is because it has billions of neurons, known as cells.
In spite of many medical studies and researches, nobody has ever understood the complete working of these neurons, to date.
Different Parts of a Frontal Lobe
The frontal lobe can be divided into four different parts, which are known as the lateral part, polar part, orbital part and the medial part. Each of these parts has particular types of gyrus in them and they are:
- The lateral part consists of superior frontal gyrus, middle frontal gyrus, and inferior frontal gyrus.
- The polar part consists of transverse front polar gyri and front marginal gyrus.
- The orbital part consists of lateral orbital gyrus, anterior orbital gyrus, posterior orbital gyrus, medial orbital gyrus, and gyrus rectus.
- The medial part consists of superior frontal gyrus and cingulate gyrus.
All of the gyri are separated by sulcus or sulci. The sulci are indentations or grooves in the brain, while gyri are the bends and folds.
The above parts are further divided into small parts that perform different functions. Some of these parts and the functions they perform are briefly explained below:
- Broca’s area is situated in the left frontal lobe. The Broca’s area region of the frontal lobe is responsible for speech and language production. This is the part that helps in putting thoughts into words.
- The primary mortar cortex is a part of the frontal lobe, which is responsible for the mortar functions like voluntary movements, walking, running etc.
- The frontal lobe is the part of the brain that has rational thinking ability. Hence, it helps in categorizing and comparing objects and then making a difference between the compared objects.
- The frontal lobe is one of the vital parts in retaining long term memory. Though the different parts of the brain are responsible for memory, the frontal lobe helps in retaining the memories for a long time.
- The frontal lobe is that part of the brain, which is the most important for empathy. That is, the frontal lobe helps in understanding and having a reaction to others’ feelings.
- The frontal lobe is vital for the complex interplay of impulse control, memory and other functions that helps with the development of the main characteristics of each individual. In other words, the frontal lobe is responsible for personality formation in a person.
- The neurons that are dopamine sensitive are found in frontal lobes, which help in the formation of feelings of reward and motivation.
- The frontal lobe is responsible for attention. Hence, it helps a person to manage attention and also to have selective attention. A lack of managing attention may lead to Attention Deficit Disorder (ADHD).
How to Find out the Damage in Frontal Lobe and Treatments for the Damage
A frontal lobe can get damaged due to a variety of reasons. Some reasons may be due to natural deficiencies, while some other reasons for the damage are caused due to accidents or illness.
A frontal lobe may get damaged due to a stroke, accident which involves a heavy blow to the head, growths in the frontal lobe and diseases. Regardless of the reason, the damage to a frontal lobe can lead to the following symptoms:
- Speech problems
- Changes in personality
- Poor coordination
- Drastic impulses
- Trouble planning
- Trouble in keeping up with a schedule
Treatments for Frontal Lobe Damage
One of the important points about treating a frontal lobe injury is to find out the cause of the injury and try to work out treatments for the damage depending upon the cause of injury to the frontal lobe.
Some of the different types of treatments for a frontal lobe injury or damage are medication, surgery, counseling, etc.
A frontal lobe injury or damage may be caused because of a stroke. When a stroke is the cause of the damage or injury to the frontal lobe, then the doctor who treats the frontal lobe injury may prescribe specific medications.
In addition to the medication, doctors may also ask the patient to start having a healthy lifestyle by consuming a healthy diet every day and doing regular exercises for the body and mind. Proper and regular exercises are enough to keep the body fit. A regular schedule of meditation is good enough to keep the mind at peace.
The frontal lobe may also get damaged and injured due to accidents. Most of these accidental injuries or damage may cause speech impediment, memory loss, personality change, behavioral changes etc. These types of damages can be treated through surgery, medication, and therapy.
All these treatments mainly focus on recovering most of the functions of the frontal lobe. This is because, without a proper frontal lobe, a person cannot make any rational decisions.
Recovery from frontal lobe damage or injury is a very unpredictable process. Some may recover within minutes or hours after treatment, while in some cases, the recovery takes a long time – as long as a few years!
In worst cases, a full recovery is never made after a frontal lobe injury. Progress of the treatment may occur suddenly and infrequently making the ability to predict the result of the treatment almost impossible.
We hope you would have now got an idea about the importance of the frontal lobe, its maturity phase and why it is important to take care of it properly.
