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

What has been a major contribution to accelerating our understanding of adolescent brain development?

• The decrease in brain volume

• The use of fMRI to study brain structure and function

• The ability to perform brain surgeries

• The development of medications for brain health

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

• It limits the ability to perform complex tasks

What is the primary function of synapses in the human brain?

• To transmit electrical charges through a neuron

• To connect the brain's left and right hemispheres

• To protect neurons from damage

• To store energy for neuron activity

By what age does the rate of synapse formation peak in early childhood?

• At birth

• Age 1

• Age 2

• Age 5

What analogy is used in the text to describe synaptic pruning?

• Trimming a hedge

• Pruning a rose bush

• Cutting grass

• Cleaning a room

According to the text, what happens to synaptic pruning during adolescence?

• It stops completely

• It slows down significantly

• It continues and is necessary for normal brain development

• It only occurs in certain regions of the brain

How does the presence of peers affect adolescents' brain activity, according to the study mentioned?

• It has no noticeable effect

• It decreases brain activity

• It increases focus on the costs of decisions

• It increases focus on the rewards of risky choices

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.
