A new study found that new cells were created almost entirely in the human brain. It is assumed that at least for 97 years this process is going on. It was thought that the number of living cells in the brain will remain the same at the time of birth, so the new concept will cause a lot of controversy. A group of researchers from the University of Madrid have also shown that the number of new cell formation has been closed with age. And in the early stage of Alzheimer's disease, the number of cells decreases dramatically - so that research for dementia or dementia causes new ideas. Most cells in our brain send electrical signals between themselves known as neurons - and this process starts from our birth. In the case of other mammals, studies have shown that new cells have been created in their brain even later in life. But there is debate about the emergence of new neurons or the process that is called 'neurogenesis'. This study, published in the journal Nature Medicine, was done with 58 brain dead brains. The age limit was 43 to 97. The main focus is to call a brain or hippocampus - which plays a role in controlling memory and emotions. This part of the brain is used to remember where you parked your car. New neurons Since birth, neurons do not have full form of the brain, it gets replenished with the process of growth and maturation. Researchers have identified this immature or 'new' neurone in the brain. With the age of a healthy brain, the amount of neurogenesis or neurone growth is seen as 'slightly less'. Researcher said. Maria Lawrence-Martin told the BBC, "I believe, as long as people are learning new things, new neurons are increasing, and it is happening every moment of our lives." But the case is different for Alzheimer's patients. The number of new neurons in the initial phase of Alzheimer's has decreased from 30,000 to 20,000 in every millimeter. Dr. According to Lawrence-Martin, "At the beginning of the disease this reduction is 30%." Alzheimer's disease is not yet cure. Although many studies using this method have failed in the past week and the latest research shows that something special is happening in the beginning of the disease. Dr. Lawrence-Martin says that if you understand that neurogenesis can be reduced, then its knowledge can be applied to Alzheimer's and normal age-related diseases. But he thinks that in the next phase of this research, maybe there is a need to monitor the brain of living beings. Looking at what happens there over time.
