- By two years, the human brain has grown to 80% of its original size. From this time, neurons and glia work together to refine the newly created synapses and circuits, a process that continues through adolescence. The brain is considered full size around age 14, but circuitry continues to rewire until early adulthood.

The making of the human brain from the tip of a 3 millimeter neural tube is a marvel of biological engineering. To arrive at the more than 100 billion neurons that are the normal complement of a newborn baby, the brain must grow at the rate of about 250,000 nerve cells per minute, on average, throughout the course of pregnancy.

Nov 3, 2010 · The mature human brain has a characteristic pattern of folds (the sulci) and ridges (the gyri). The enfolding of the mature brain is thought to be an adaptation to the dramatic growth in the size of the brain during the course of evolution.
