How does the teenage brain have an evolutionary advantage?
“Compared to adults, adolescents have more [reward center] activation when they’re learning a new task, and this greater activation helps them learn from the environment in a more adaptive and efficient way than the adults,” said Galván.
What did you learn about the mysterious workings of the adolescent brain?
In her remarkable TED Talk, “The Mysterious Workings of the Adolescent Brain,” cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically “teenage” behavior is caused by the growing and developing brain.
What have scientists found about the adolescent brain in the last decade?
In the last decade, a growing body of longitudinal neuroimaging research has demonstrated that adolescence is a period of continued brain growth and change, challenging longstanding assumptions that the brain was largely finished maturing by puberty [1–3].
What brain mechanism does Casey 2008 propose might underlie risky Behaviour in adolescence?
The “Imbalance Model,” discussed in Casey et al’s 2008 paper, also proposes that the developmental trajectories of two brain systems, implicated in reward response and top-down control, respectively, confer heightened vulnerability to reckless behavior in adolescence.
What happens to your brain when you become a teenager?
Other changes in the brain during adolescence include a rapid increase in the connections between the brain cells and making the brain pathways more effective. Nerve cells develop myelin, an insulating layer that helps cells communicate.
Which quality is most likely to promote thriving in a teenager?
The quality MOST likely to promote thriving in a teenager is having: a passion or talent that is encouraged by a caring adult.
What changes happen during adolescent?
Adolescence is a time for growth spurts and puberty changes. An adolescent may grow several inches in several months followed by a period of very slow growth, then have another growth spurt. Changes with puberty (sexual maturation) may happen gradually or several signs may become visible at the same time.
How is adolescent brain different?
Because the prefrontal cortex is still developing, teenagers might rely on a part of the brain called the amygdala to make decisions and solve problems more than adults do. The amygdala is associated with emotions, impulses, aggression and instinctive behaviour.
What is the paradox of adolescence?
The prevalence of mental health issues among young people is not difficult to notice. Never in any other time in my life have I met so many people struggling, or who have struggled recently, with mental illness.
