Question

Adolescence and late adulthood are times when we may see significant behavior and cognitive change. With adolescence, how is brain development related to adolescent impulsivity and what areas of the brain are indicated in adolescent behavior? With aging adults, what areas of the brain are impacted in later adulthood and what functional changes are noticed as people age?

Answer 1

Most impressive findings concern the protracted maturation of the performal cortex (PFC) and parietal regions. If appears that around age 11, and the Performal Corlet and parietal regions (or) lobes begin a period of prolonged pruning of neuronal axons resulting in thinning of cortical grey matter. 2 process of brain maturation that predispose the adolescent to risk taking and impulsivity - (a) That energies early in adolescence is driven by front striatal reward circuits involving the ventral striation. These Circuits mature relatively easy and encourage the adolescent to venture away from the family and toward increasingly novel and adult - like activities. Not Surprisingly, many of these activities are taught with a Certain amount of risk. Eg: - Driving. (b) The PFC and its connections with other brain regions are thought to be structurally inadequate to provide the Control that is optimal for adolescent behavior. This maturational gap in development of PFC
