Document Summary

During infancy, a baby grows from newborn to toddler, and during childhood from toddler to teenager. Maturation biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience. Maturation (nature) sets the basic course of development; experience (nurture) adjusts it. Brain development the explosive rate of nearly one-quarter million per minute. The developing brain cortex actually overproduces neurons, with the number peaking at 28 weeks and then subsiding to a stable 23 billion or so at birth. In your mother"s womb, your developing brain formed nerve cells at. From infancy on, brain and mind neural hardware and cognitive software develop together. On the day you were born, you had most of the brain cells you would ever have. However, your nervous system was immature: after birth, the branching neural networks that eventually enabled you to talk, talk, and remember had a wild growth spurt.
