In the womb of the human body, when the age of the human cell is 42 days, the brain starts to build. At this time, an average of 250,000 neurons is created every minute. Most of the human brain neurons are formed after the fetus is 6 months old. Needless to say, most of the 85-86 billion neurons in the adult population are ready at this time.
However, there are various types of work, including the establishment of interconnection between neurons. A cell divides into another cell to form another cell similar to that, but the specialized neuron-cells are not separated. Let’s compare this matter to an event of daily life. A lot of neurons can be compared with the rod used to build the house. As the rods spread everywhere from the foundation of the house, so our neurons spread evenly to the leaves of the feet. As soon as the house is built, it would be impossible to plant a new rod in a fracture, just as the scientists thought the human brain neurons were much like this. In 1913, renowned neurologist Santiago Ramon introduced this concept from some of his findings.
Because the analysis of the neuron cells shows that the newly formed components are not neurons. So scientists had long believed that neurons did not create their copies. As a result, there is a possibility of creating new neurons in the adult human body at zero. But why?
New neurons may also be produced by adults
Recent studies have said that neurons may also be redesigned in adults. And this process is called ‘neurogenesis’. But not by splitting from the old neuron, but through another process. Let’s know about the process and how important it is to cure the brain’s various diseases.
What is this neuron?
Neurons are the nervous system bricks. With this brick-built nervous system, we feel everything around us. This nervous system involves all our life and all our life with cold or hot feelings, good or bad decisions. The nervous system can be divided into two parts.
- The nervous system headquarter or the capital is called the central nervous system. It is made up of the brain and spinal cord.
- The ground worker of this system, which has every limb, is called the endemic nervous system. Suppose, if you have a mosquito bite in your hand, then its information will reach the nervous system headquarters in the field of nerves in a fraction of the second.
The main function of body fluid is through neurons. So if your neurons are damaged for any reason, then it is necessary to say that the body will gradually become stagnant if it cannot take it back to the previous state. And those who suffer from Parkinson’s, Alzheimer’s, and Huntington’s disease, gradually decreasing their neuron levels. As a result, these diseases are known as neurodegenerative disorders. If the number of people suffering from these diseases increases at an alarming rate, this discovery might lead them to normal life.
Where is this neurogenesis?
New neurons are formed in the human brain called the ‘Hippocampus’. The neural stem cell, which is also known as Neural stem and progenitor cell, is located in the region. These cells are divided into new neurons. This region of the brain has been making human neurons for most of the time in life. And this ‘Hippocampus’ is essentially associated with people’s long-term retention, acquired education, and emotion. Scientists discovered it in 1990 this regard. However, scientists initially thought this process might be related to a new disease. It is essentially a process of making new neurons when it comes out in a large study. If you want to, you can see this lecture given at Sanderin Thurret’s ‘Ted Talk’, a scientist working with neural stem cells in recent years.
How can new neurons be understood?
The age of any cell can be determined using a radio-isotope named carbon-14. So the Hippocampus region of the brain and its surrounding cells has been diagnosed through this process, several cells are being developed in this region. It is estimated that around 700 new neuron cells are being added to the brain’s Hippocampus area every day. However, researchers of neurogenesis have come out of the information obtained that excessive amounts of smoking, uncontrolled drinking, high blood pressure, or mental turmoil can hinder this process. Only due to mental turmoil, the rate of preparation of new neuron cells can be reduced by 10%. Besides, there may be some tendency for new neurons to be created in individuals and groups due to some hereditary and environmental factors.
The previous idea was wrong then?
As the analysis of neuron cells shows that the central element is not needed for a division, so for a long time, the scientists thought the neurons were not divided. This idea is not wrong at all. The new neurons produced in the hippocampus area are not separated from the old neurons. Rather, this is the case of making new neurons from the neural stem and progenitor cells in the area. And this process is not seen in most areas of the brain. So, how much is the area of building new neurons in the brain, it can be understood only by one calculation. There are approximately 85 to 86 billion neuron cells in the human brain. In the Hippocampus area, only 700 neurons are produced every day. So we can understand how much low this amount is. Along with this, scientists are trying to find out the complexity of this brain and whether the new neurons are formed in such a region.
Neurogenesis to heal the disease
If the neuron cell is damaged due to injury to the brain or the disease, then scientists still do not know any procedure to repair it. Or those who suffer from Parkinson’s, Alzheimer’s, or Huntington’s disease, gradual decrease in their neuron levels. These neurodegenerative diseases have not yet been diagnosed with any treatment. So scientists believe that the process of creating new neurons in the Hippocampus area can play a significant role in the treatment of these two types of diseases. As well as new neurons that do not form a large part of the brain, neurons in those regions are damaged. However, following this process, new neurons can be generated.
