Summary
Basic organization of the CNS is established during the embryonic and early fetal period (see Chapter 19). However, at this stage, the human brain is barely formed. From the 20th to the 40th week of gestation, brain weight increases tenfold. It doubles again during the first year of postnatal life, and continues to increase another 50% during the next 10 to 15 years when adult weight is finally reached (see Chapter 26) (1). Growth is accomplished through several processes. The quantity of brain cells increases at a brisk rate in the periventricular germinal matrix until approximately 30 weeks gestation and at a much lesser rate until approximately full-term gestation (2).
