What are the steps of the development of the nervous system?
- Neurons start to develop at 4 weeks, gene expression and signal transduction will determine where they will be formed
- There are more neurons developed then needed, so the neurons are going to compete with each other and the neurons that are not needed are eliminated.
- Then the neurons that survived will form too many synapses so synaptic pruning has to take place.
Which neurons will survive?
