In addition, the nucleus accumbens in the brain matures much more quickly than the prefrontal control system. The accumbens is known for reward, pleasure, addiction and laughter. It is very closely connected with the limbic system, so it produces many of the same effects. In fact, the accumbens has been found to be even more active in adolescents than in adults. This also influences many of the behaviors found in adolescents. In addition to a quickly maturing limbic system and nucleus accumbens, the profrontal cortex takes much longer to develop. An undeveloped cortex can lead to shortsightedness in an emotional situation. The adolescent cannot determine potential future outcomes and therefore will make a decision based in an emotional context and not plan for long-term gains. The maturation process of the cortical and subcortical systems is divided into three parts. First, there is mass production of axons and synapses, more than in other times of life. Then, there is “pruning” of the synapses. However, there is continued development in the amygdala and prefrontal cortex into early adulthood while the limbic system matures much faster. Some of their evidence is evolutionary and not biological. In animals and ancient cultures, an adolescent needs to leave their family and home to find a mate and begin their own life. The article argues that the risk-taking behaviors were necessary for the adolescent to leave. If they did not feel the urge to be impulsive and risky, they would not leave their family and would not perpetuate the species. The change in behaviors is accompanied by an increase in sex- seeking behaviors, which allows the adolescent to find a sexual partner.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
