Why do not we remember the first years of our life?

Nobody (or almost nobody) remembers the first years of his life, and we can not do anything about it! However, this phenomenon has a scientific and biological answer.

In Canada, a group of researchers concluded thatnot remembering the experiences that nWe lived during the first years of our life is due to the neuronal growth that corresponds to this stage of development.

This means that the production of new neurons (which aims to increase learning levels during growth) has a negative effect on memory.

What is neurogenesis?

In simple terms, neurogenesis is the process of creating new neuronal cells in our brain, and especially in the region called the hippocampus (it is directly related to memory and learning).

This process has two peaks: before and after birth, with childhood and adulthood being periods of decline.

According to the author Huttenlocher, during the first year of our life, our brains have twice as many neuronal connections as in adulthood.

Scientists have discovered that the main factor in the decline of these neuronal connections is, without a doubt, the experiences gained with age.

The basics of the study

Although it has been shown in the past that childhood memories may persist in the short term (and get lost in the long run), a group of Canadian researchers decided to look at the reason for this phenomenon.

Through experimentation with rats (both young and adults alike) to modify their neuronal processes, the researchers found a direct relationship between neuronal growth and memory recovery, which explains the amnesia on the brain. long-term memories of childhood, and the difficulties of remembering them as adults.

From birth until the first 4 or 5 years of our life, our hippocampus is in a state of constant dynamism, which is reflected in the opposite way in the establishment of memories in the long term.

These findings in the field replace earlier theories that childhood amnesia was due to speech development and other faculties related to biological and social growth.

While these findings in Canada are not sufficient to provide an irrefutable answer to this question, they are certainly an innovative starting point for different studies of this mysterious topic,which researchers absolutely want to bring an element of answer.

This means that among all the mysteries that remain in the field of neurology, the cause of infantile amnesia is about to be revealed.

What to deal with this absence of memory?

We can say that there is no harm in not remembering the first years of his life.

Perhaps the best advice is to listen to other people relate these memories (family members, friends, etc.) to create anecdotes that, even if we do not remember them properly, will help to define our own history, and to improve our social bonds.
