When the human cell has been around for 42 days, development of the brain in the fetus begins. This occurs in the womb of the human body. At this point in time, around 250,000 neurons are being generated per minute on average. The vast majority of neurons in a human brain are not produced until after the fetus has been developing for at least six months. It goes without saying that the vast majority of the adult population’s 85–86 billion neurons are ready at this point in time. This page will describe the process of neurogenesis; if you have any questions, please leave them in the comments section.
Nevertheless, there are many other kinds of labor to be done, one of which is the formation of interconnections between neurons. When one cell undergoes cell division, it gives rise to another cell that is quite identical to itself; however, the specialized neuron cells are not segregated out at this stage. Let’s relate this situation to something that happens in our everyday lives. There are many neurons that may be likened to the rod that was used to construct the building. Similar to how the rods in the home extend out in all directions from the foundation, our neurons are dispersed uniformly from the head to the toes. It would be hard to plant a new rod in a fracture after the home is created, much as the researchers believed the neurons in the human brain were very similar to the structure of this house. This theory was first proposed by the well-known neurologist Santiago Ramon in 1913, based on some of his own discoveries.
Since examination of the neuron cells reveals that the newly produced components are not neurons, this is due to the fact that. Therefore, for a very long time, scientists assumed that neurons did not produce duplicates of themselves. As a direct consequence of this, the probability of the mature human body producing new neurons is equivalent to zero. However, 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 headquarters 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 on your hand, then its information will reach the nervous system headquarters in the field of nerves in a fraction of a 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 decrease 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?
In the area of the human brain known as the “Hippocampus,” new neurons are created. The area contains the neural stem cell, sometimes referred to as the neural stem and progenitor cell. New neurons are created by dividing these cells. Human neurons are produced in this area of the brain during the majority of a person’s lifespan. Additionally, the “Hippocampus” is substantially linked to people’s long-term memory, acquired knowledge, and emotion. In this context, it was found by scientists in 1990. Scientists, however, first hypothesized that this activity may be connected to a new illness. When it is discovered in a sizable investigation, it is simply a process of creating new neurons. You may see this talk given by scientist Sanderin Thurret, who has recently worked with neural stem cells, at his “Ted Talk” event, if you’d like.
How can new neurons be understood?
Using a radioactive isotope known as carbon-14, it is possible to calculate the age of every given cell. As a result of this process, the area of the brain known as the hippocampus and the cells that surround it have been identified. Additionally, this region is experiencing the development of many cells. It is believed that around 700 new neuron cells are being added to the hippocampus region of the brain on a daily basis. However, researchers of neurogenesis have come to the conclusion from the information acquired that large quantities of smoking, uncontrolled drinking, high blood pressure, or emotional anguish may all inhibit the process of neurogenesis. It is very possible that the pace at which new neuron cells are being prepared for use is slowed down by ten percent owing to mental disturbance. In addition, there is a possibility that certain people and groups have a greater propensity than others to generate new neurons as a result of various inherited and environmental variables.
The previous idea was wrong then?
Because an examination of neuron cells reveals that a core component is not required for a division to take place, scientists were under the impression for a considerable amount of time that neurons did not undergo division. This is a very valid point of view. In the region of the hippocampus, new neurons are generated, but they do not exist in isolation from the existing neurons. Instead, this is an instance of the creation of new neurons from neural stem cells and progenitor cells that are present in the region. In addition, this process is not seen in the majority of the brain’s regions. One calculation is all that is necessary to have an understanding of how much space in the brain is devoted to the generation of new neurons. In the average human’s brain, there are somewhere between 85 and 86 billion neuron cells. Only 700 new neurons are born each day in the region of the brain known as the hippocampus. In order for us to get a better understanding of how little this quantity is. In addition to this, researchers are looking at the intricacy of this brain as well as the question of whether or not new neurons can be produced in this particular area.
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.
