Ming is pregnant, and she has heard that the brain of the fetus is rapidly developing during pregnancy. She would like to know more details. Name and describe for Ming the four main processes in brain development during pregnancy.

What will be an ideal response?

The ideal answer should include:
1. There are four main processes in brain development that happen after the neural tube is formed. These processes are neurogenesis, neural migration, neural differentiation, and formation of neural connections.
2. Neurogenesis involves the production of about 200,000 neurons per day. It is complete by the fifth prenatal month.
3. Neural migration involves the movement of neurons from the center of the neural tube outward to form the layers of the brain. It is complete by the seventh prenatal month.
4. Neural differentiation involves the taking on of specific functions by particular neurons, influenced by both genes and chemical signals from neurons around them. This process occurs in parallel to migration and is substantially complete by the seventh prenatal month.
5. Formation of neural connections involves the generation of synapses that allow electrical signals to be transmitted from one neuron to another.
