There is an array of opinions as to when a person fully matures. Should the legal age of adulthood be lowered or raised? At what age do you think you are grown?
Neuroscientists now know that brain maturation continues far later into development than had been believed previously. Significant changes in brain anatomy and activity are still taking place during young adulthood, especially in prefrontal regions that are important for planning ahead, anticipating the future consequences of one’s decisions, controlling impulses, and comparing risk and reward. Indeed, some brain regions and systems do not reach full maturity until the early or mid-20s. Should this new knowledge prompt us to rethink where we draw legal boundaries between minors and adults?
