Week by Week Developments

The brain of a baby starts developing as early as three weeks into pregnancy. However, the development process is a complicated one and takes place in different stages. Here is a breakdown of the week-by-week developments of the baby’s brain:

Week 3 to 4

At this stage, the neural tube, which will eventually form the brain and spinal cord, starts forming. The neural tube develops into three primary parts: the forebrain, midbrain, and hindbrain.

Week 5 to 6

The brain starts to develop specific regions, such as the cerebral cortex, brainstem, and cerebellum. These regions will control various body functions such as balance, movement, and coordination.
