Brain growth continues fifteen years after birth through self-formation

Evidence

We use the term plasticity precisely to characterize this neuronal genesis. The brain, in effect, forms itself. ”The human infant is born with a brain weighing about 300 grams—20 percent of the weight of an adult brain… . One of the major features of the development of the human brain, then, is that it continues well after birth, for about 15 years.” — Catherine Malabou, What Should We Do with Our Brain?, 71
