Abstract

The prefrontal cortex undergoes one of the longest periods of development of any brain region, taking over two decades to reach full maturity in humans. This chapter focuses on normal development, dividing it into the following epochs: 0-1 years, 1-3 years, 3-7 years, and 7 years through early adulthood. For each epoch, it summarizes some of what is known about the development of the working memory and inhibitory control functions that depend on PFC and the anatomical and biochemical developmental changes in PFC during that period.
