'The proper functioning of the brain in adolescence conditions the behavior as adults The ability to interact with others is essential to the stability of social networks, reproduction and survival of mammals. Humans are no exception to the rule and even be sociable or not is something that is learned day by day, scientists at Yale University (USA) showed that the generation of more or less neurons during adolescence would be crucial on an individual's ability to socialize with another. Although for decades it was thought that humans were born with a predetermined number of neurons, we now know that they continue to be formed throughout life in specific brain regions after birth. This process, called neurogenesis, has been extensively studied in the embryonic period and in old age, but not in adolescence. The study led by Arie Kaffman and published in the journal Neuroscience (2011), indicating that neurogenesis in the stage of childhood and adolescence determines the level of sociability that a person acquires. When creating new brain cells is interrupted in adolescence, individuals become deeply antisocial to adulthood. However, if the same neural process is interrupted in adults, no changes in behavior.'
