Neural Development Flashcards
1
Q
What are neurons?
A
- It store and transmit information to other neurons in the brain
2
Q
What are synapses?
A
- Gaps between neurons
- Fibres from neuros get close to each other here
3
Q
What are neurotransmitters?
A
- Information transmitted between neurons through chemicals
4
Q
What are special about neurons?
A
- They can differentiate
- Needs stimulation from the environment
Use it or loose it - if you dont use the skill, braincells loose its function to perform it later
5
Q
Why does the brain have programmed cell death?
A
- To make space for synaptic connection between neurons
- To learn new things
6
Q
Why is there an overabundance of synapses early?
A
- Ensure domains specific skills can develop
- Few new neurons are created after prenatal period, thus alot gets created before birth
7
Q
What is glial cells?
A
- Important for neurons to function
- Causes changes to the brain size
- Responsible for myelination - layer around neural fibers
8
Q
What is myelin?
A
A fatty substance that improves the efficiency of information transfer
9
Q
What is synaptic pruning?
A
Putting neurons in a latent state, to be ready to support future development
10
Q
How can we stimulate neural development?
A
- New sensory experiences, challenge one self and change things up
- Try out new things
- Get a new job
