How Teenagers' Brains Are Actually Wired Differently

What significant change occurs in the human brain during adolescence?

• It shrinks in size.

• It undergoes extensive remodeling and development.

• It stops forming new connections.

• It becomes less active.

Besides affecting mood and sexual development, what other vital roles do hormones play in the human body?

• They only control hair growth and skin oiliness.

• They regulate heart rate, hydration, and the growth of organs, bones, and muscles.

• They are solely responsible for determining sleep cycles.

• They only influence how much a person eats.

Why do teenagers often have a later sleep schedule compared to adults?

• Their bodies produce more cortisol at night, keeping them awake.

• Their internal sleep clocks shift, causing melatonin release to be delayed.

• They naturally require less sleep than younger children or adults.

• They are more sensitive to light, which keeps them awake longer.

Which part of the brain is primarily responsible for controlling impulses, emotions, and making sound judgments, and when is it typically fully developed?

• The cerebellum, which is fully developed by age 6.

• The prefrontal cortex, which continues to develop until the mid-20s.

• The brainstem, which is fully developed in early childhood.

• The hippocampus, which is fully developed during puberty.

Which part of the brain is the last to fully develop during adolescence?

• The brainstem

• The cerebellum

• The prefrontal cortex

• The amygdala

What is the process called when the brain gets rid of connections that are not used enough?

• Neural growth

• Synaptic pruning

• Brain expansion

• Cerebral thinning

When identifying emotions, which part of the brain do teenagers primarily use compared to adults?

• The prefrontal cortex

• The cerebellum

• The amygdala

• The hippocampus

How do teenage brains typically react when presented with a big potential reward compared to a small one?

• They light up more for small rewards.

• They light up more for big rewards.

• They show no difference in activity.

• They light up less for both big and small rewards.
