plasticity

Question 1

developmental plasticity

Answer 1

occurs in response to ageing and the learning associated with maturation, usually occurs when we are a fetus to 25 years old

Question 2

adaptive plasticity

Answer 2

occurs in response to a need to adapt, such as in response to brain trauma and injury

Question 3

features of the adolescence brain

Answer 3

corpus callosum develops more connections between hemispheres
the cerebellum has an increased number of neurons and synapses
frontal lobe develops which allows better motor movement and high order thinking
amygdala becomes more active

Question 4

sprouting adaptive

Answer 4

the ability for a neuron to develop new branches on the dendrites or axons, usually when the neuron has been damaged

Question 5

rerouting adaptive

Answer 5

involves an undamaged neuron forming a new connection with another undamaged neuron

Question 6

stage 1 developmental plasticity - proliferation

Answer 6

when we are a fetus, our neurons form

Question 7

stage 2 developmental plasticity - migration

Answer 7

our neurons move from where they are first formed in the brain to where they will stay in the nervous system, this occurs in the fetal period

Question 8

stage 3 developmental plasticity - synaptogenesis

Answer 8

the axons of neuron grow and from connection to nearby neurons creating synapses, this occurs mostly in infancy

Question 9

stage 4 developmental plasticity - synaptic pruning

Answer 9

the process of eliminating synaptic connections, it fine tunes the neural connections so you either use it or lose it, this occurs mostly during adolescence

Question 10

stage 5 developmental plasticity - myelination

Answer 10

the formation of white fatty myelin that coats the axons and protects and insulates them from the interference of other neurons
