Frontal lobe maturation-the prefrontal cortex is also maturing at this point in Randall's life. The PFC is not finished maturing until the mid-20s, so 15-year-old Randall may have some advanced cognitive skills relative to his preadolescent self, but he is not yet fully mature. This, too, explains the discrepancy in his understanding of right and wrong and his choices to make risky decisions. Also, changes in the limbic system occur at puberty, though the PFC, the part of the brain that is responsible for decision making, planning ahead, and controlling impulses, is not fully mature until the age of 25 or so.
