Through several experiments with rodents, a group of scientists from Japan and Canada have tried to decipher the memory elimination mechanism. They say that the responsible is the process of creating new neurons.

The most curious thing is that the creation of new neurons is essential for new memories to emerge. It used to be believed that you couldn't create more neurons after you were born, but today we know that they form throughout your life. Newly created neurons are integrated into existing networks, which is critical to the functioning of memory. At the same time, however, the readaptation of the connections also generates oblivion, as indicated by the abovementioned researchers. That is what would mean that he did not remember the events of childhood.
