Structural Biochemistry/Phases of Brain Development
Phases of Brain Development 
Phases of early embryonic brain development mainly include seven stages such as neural induction, proliferation, migration, differentiation, synaptogenesis, cell death/stabilization and synaptic rearrangement. Neural induction stage takes from the day 18 to 24 since the fertilization. Proliferation stages takes from the day 24 to day 125. Migration stage takes from the day 40 to day 160. And the differentiation stage takes from the day 125 to the postnatal periods. from the differentiation period to the postnatal period, the brain development becomes very sensitive to the environmental factors play a role in addition to the genetic factors.
