Scientists —why people do not remember their childhood
It is known that an adult does not remember the first three years of their lives.
The reason why he forgets his childhood, is, as the researchers found, a process called neurogenesis, and is easier – the division of brain cells and the formation of new ones, erasing old memories. Improving the learning ability of the newly generated neurons are simultaneously erased, almost completely, the information about the past.
Previously believed that the new cells contribute to formation of new perceptions, but, as it turned out, the oldest events from memory they erased. And it saves the brain from overload.
The author of the research, neuroscientist Paul Franklin
The child has the period of neurogenesis is most active. With age, cell division in humans, slows, as, by the way, the rodents on which the experiments were carried out, which confirmed the extended theory.
Old mice and those over the age of seventeen days, put in a cage and its floor was plagued by a weak current, which influenced the rodents. A month later, the experiment was repeated. Old mouse, remembering the negative experience previously, scientists had demonstrated the panic attack symptoms at that time, young individuals did not show concern. Just, their memories during the day were erased!
When mice developed a fear of one of the cells, artificially induced accelerated cell division of the brain, they quickly forget negative experiences, and were fearless in the cage.
