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
If synapses are week and no longer needed, the synapses are
pruned or eliminated
saved for later
put to sleep
reused for another purpose
Pruning makes teen brains more
confused
efficient and faster
forgetful
slower
The older teen brain is
more connected and complex
faster and efficient
starting to get worse
confused
distracted
