Why don’t nerve cells divide?

As if I hear you say: What is my relationship? Hear from me:
Our speech, movement, sleep, and everything in our body is driven by nerves. If damaged, how do you compensate?
Our nervous system is divided into two parts: central and peripheral. The central one is the brain and spinal cord and the other one is the rest of the body’s nerves.
The brain is still puzzled; Scientists have believed for decades that it is capable of producing nerve tissue. But a 2018 study torpedoed their hypotheses. They counted 59 samples from human brains of fetuses and adults at the age of 77 years. At the latest, the brain produces tissue until the age of one year following birth, and then stops. Despite these results, researchers are still skeptical and think that the brain produces tissue even at a later time.
Neurons are somatic cells, meaning that if they divide, their division will be equal, not equitable, like sex cells. This division requires something in the cell called the centriole, which copies the chromosomes. This centriole is not present in neurons.
They succeeded in regenerating the skin, to fight aging, but the nerve cells are still a big bump on the path of man’s search for immortality.
