Neurogenesis: The Building of the brain during Pregnancy

Neurogenesis means producing new neurons.  It starts in week 5 of pregnancy and peaks in the third and fourth month of pregnancy.

During this time, the brain is producing more and more new cells, and fast!

Wondering why you are feeling more fatigued than normal? 

During the busiest times of neurogenesis the baby’s brain is creating 250 000 neurons a minute!

During pregnancy your baby will produce almost all of the 100 billion neurons it will ever need.


This is because the brain is  capable of molding and reshaping to suit the surrounding environment.
