All of the connectors between neurons called synapses that were overproduced in a baby's brain whittle down. The more active synapses survive, shaping the brain's early architecture." Across the whole brain, these connections rewire in the same pattern from birth until about nine years old. Meanwhile, the brain's grey and white matter grow rapidly in volume.
