Explain the four important phases of brain development.
What will be an ideal response?
The four important phases of brain development involve the neural tube, neurogenesis, neuronal migration, and neural connectivity. The neural tube is the long, hollow tube developed out of the ectoderm and located on the embryo's back. If it fails to close at around 27 days after conception, it can result in anencephaly and spina bifida. Another important phase is neurogenesis, which is the massive proliferation of new immature neurons that occurs after the neural tube closes. Neuronal migration is another important phase occurring 6-24 weeks after conception in which the cells move outward from their point of origin to their appropriate locations so that they create different levels, structures, and regions of the brain. The 4th important phase of brain development is called neural connectivity and occurs around the 23rd prenatal week when connections between neurons begin to occur. This continues postnatally.
