AP PSYCHOLOGY

Detailed explanation-1: -How the brain develops. The brain matures from back to front. Starting in infancy, the brain develops from the brain stem at the back of the neck to the prefrontal cortex in the front of the brain. As noted, brain maturity is reached in the early to mid-20s.

Detailed explanation-2: -The mammalian brain develops from the core outward.

Detailed explanation-3: -The development and maturation of the prefrontal cortex occurs primarily during adolescence and is fully accomplished at the age of 25 years. The development of the prefrontal cortex is very important for complex behavioral performance, as this region of the brain helps accomplish executive brain functions.

Detailed explanation-4: -The brain finishes developing and maturing in the mid-to-late 20s. The part of the brain behind the forehead, called the prefrontal cortex, is one of the last parts to mature.

Detailed explanation-5: -The first areas to mature were those with the most basic functions, such as those processing the senses and movement. Areas involved in spatial orientation and language (parietal lobes) followed, around the age of puberty (11–13 years).
