1
Q
Tropic factors
A
Peptides that support growth, survival and differentiation
2
Q
What happens during maturation
A
Myelin growth
3
Q
Steps of neuroplasticity
A
Arborization (overgrowth)
Pruning
This happens because of competition for trophic factors
4
Q
How do axons find their path
A
Pioneer axons go out little by little
Chemicals attract or repulse axon
It can then lead other axons down its path
5
Q
What is a growth cone
A
Growing tip these can be either axons or dendrites in early stages
6
Q
Phases of making connections/finding target
A
Pathway selection
Target selection
Address selection
7
Q
Stages of cell maturation
A
Stem
Progenerator
Blast (can be glial or neural)
Specialized (interneurons, projecting neuron, oligodendroglia, astrocyte)
