Answer 1

Developmental plasticity only occurs in children and adolescents is the ability for synapses to be modified, whereas adaptive occurs in both children and adults, it allows for increased neurotransmitters

Question 2

The 5 stages of developmental plasticity

Answer 2

Proliferation
Migration
Circuit formation
Synaptic pruning
Myelination

Question 3

What is synaptogenesis

Answer 3

When axons of new neurons grow out to target cells - form synapses with them

Question 4

What structures of the brain undergo development during adolescence?

Answer 4

Increase of number of neurons and synapses in cerebellum
Amygdala becomes more active
Corpus callosum thickens and there is increase of number or nerve fibers between the two hemispheres
