Psychology – Chapter 11 The Brain Adolescent is a transitional period between childhood and adulthood. In adolescence the corpus callosum thickens, i.e. more brain connections form. This allows information to be processed more efficiently. The corpus callosum is the site where fibers connect the brain’s right and left hemispheres. The prefrontal cortex doesn’t finish maturing until near adulthood or approximately between 18 – 25 years of age, or maybe later. The amygdala which is the location of emotions such as happiness or sadness matures earlier than the prefrontal corterx. Research has shown that although adolescents are capable of very strong emotions, their prefrontal cortex has not sufficiently developed to be able to control their emotions. The question has been asked - which come first, the biological changes in the brain or the experiences that stimulate these changes? Scientists have not been able to answer these questions although studies have been conducted. For example a study in which the prefrontal cortex thickened and more brain connections formed when adolescents resisted peer pressure. Adolescent - The Brain and Adolescents Sexuality
