Brain Development

This is the process in which neural pathways used often are strengthened

• synaptic pruning

• limbic system

• myelination

• prefrontal cortex

This is the process in which neural pathways not used often are eliminated

• synaptic pruning

• myelination

• limbic system

• prefrontal cortex

This is the region of the brain responsible for critical thinking, decision making, and considering consequences

• limbic system

• synapses

• neurons

• prefrontal cortex

At about what age is the brain finished developing in size?

• 5

• 12

• 20

• 25

At about which of the following times in one's life, is the brain finished developing?

• childhood

• adolescence

• mid 20s

• it doesn't stop developing

What is the space between cell bodies known as?

• axons

• dendrites

• synapse

• myelin

The formation of new synapses between the brain's neurons is known as

• neurogenesis

• synaptic pruning

• synaptogenesis

• myelination

The process of myelination begins

• after birth

• before birth

• at 6 months old

• at 3 months old

The very last area of the brain to mature is the

• occipital lobe

• hippocampus

• prefrontal cortex

• cerebral cortex

One explanation of 'immaturity' during the teenage years is

• lack of myelination

• too much synaptic pruning

• underdeveloped prefrontal cortex

• lack of synaptogenesis
