Researchers report adolescent cannabis use alters the structural development of the prefrontal cortex, an area of the brain that helps control higher cognitive functions.
A positive correlation has been identified between prosocial and rebellious behaviors in teens. The more risk taking behaviors a teen exhibited, the more likely they were to act prosocially. The findings suggest the same developmental processes are at work for both types of behaviors. Also noted was faster brain development in the medial prefrontal cortex predicted a decrease in rebellious behavior.
Researchers report those who are more prone to take risks while playing a simple children's game may be more prone to risky behaviors, like binge drinking.
A neuroimaging study reports connections between certain brain regions are amplified in teens who are more prone to taking risks.
Researchers suggest older people may be less likely to take risks due to declining dopamine levels.
