ELA: Demystifying the Adolescent Brain Quiz

What is the primary focus of functional magnetic resonance imaging (fMRI) as used in brain development studies?

• To identify tumors and torn ligaments

• To examine how the brain functions during specific activities

• To take pictures of the brain's anatomy only

• To monitor the brain's volume changes over time

According to the text, why is adolescence considered a significant period for brain development?

• It is the only time the brain undergoes dramatic changes

• It marks the beginning of physical development

• It is when the brain reaches its adult size

• It is characterized by dramatic brain changes more than any other life period

How does greater interconnectiveness among brain regions affect adolescents according to the text?

• It decreases the brain's ability to process information

• It allows for better communication between parts associated with different functions

• It results in a reduction of brain activity

What is the primary function of myelin in the brain as described in the text?

• It acts like a barrier to protect neurons.

• It increases the speed of neural impulses and improves information transmission.

• It connects different parts of the brain.

• It decreases the speed of neural impulses.
