Brain Development Quiz 1

What is pruning in the context of brain development?

• Strengthening of synapses

• Elimination of synapses

• Creation of new synapses

• Division of synapses

What happens to childhood connections that are still used and needed?

• They are eliminated

• They are ignored

• They are strengthened

• They are divided

What is myelination?

• Development of a fatty layer around the axion

• Elimination of synapses

• Creation of new neurons

• Division of axons

Why is myelination important?

• It slows down cognitive development

• It enhances cognitive development

• It eliminates executive function

• It reduces neuron protection

• improves ability to control behavior or self-regulate

Why is myelination important?

• makes brain faster and more efficient

• slows cognitive development

• improves executive function

• protects neuron

• reduces ability to self-regulate

What is the goal of the remodeling period in the teen brain?

• To regress the maturation of the brain

• To progress the maturation of the brain

• To eliminate brain connections

• To slow down brain development

At what age does the brain typically reach maturity due to remodeling?

• 15 years

• 20 years

• 25 years

• 30 years

What role does synaptic pruning play in brain development?

• It strengthens unused synapses

• It increases the number of neurons

• It refines neural connections

• It decreases brain plasticity

How does myelination affect neural transmission?

• It speeds up signal transmission

• It slows down signal transmission

• It blocks signal transmission

• It has no effect on signal transmission

Which process is crucial for the maturation of the prefrontal cortex during adolescence?

• Myelination

• Axonal sprouting

• Neurogenesis

• Synaptic pruning
