DEVELOPMENT OF FETAL BRAIN WHEN PREGNANCY

AGE OF PREGNANCY
 
3-4 WEEKS (0-1 Months)
At this age is a process of formation of plates, tubes, and nerve cells. Neural tube develops into the brain tissue, spinal cord, skull, vertebrae, and the network covers.
 
5-12 WEEK (2-3 Months)
Is the formation of brain tissue structure. If there are problems, disorders later lead to the formation of the face (the face and eyes can be smaller). If interference occurs in the mid-brain, the anatomy of the eye becomes impaired, such as her only one, there is a tumor, and so on but not a visual impairment.
 
13-16 WEEK (3-4 Months)
Brain tissue cells doubled in number and greater in size. If there is a problem at this stage, the child's intellectual development can be disrupted. Such as motor disorders, vision, and hearing.
 
UP TO 20 WEEKS (5 Months)
Cells that have been increasing in number and enlarged, will move to the purpose of each in accordance with its function. Example, to establish a network of brain cells will move into the brain tissue. Nerve cells are responsible for managing the hands will move toward the area to hand nerves. If any of these cells move due to brain system disruption it will be no good.
 
WEEK 21 (5 MONTHS) above
The cells that had migrated to function better. Branches of brain cells will multiply. Between one cell to the other cells are interconnected. Brain cells and also increases network ikat and interconnected. The longer the circuit is more complex.
 
AFTER THE BIRTH TO AGE 5 YEARS
This period is a time of neuronal development and brain very quickly, especially myelination. Fastest process is when the baby is born until the age of 1 year.
Myelination is a maturation period sheath of nerve cells and nerve fibers of the brain. The envelope function is take command response. So when the myelination process is good then the child is also getting good response. A simple way to determine the presence or absence of impaired myelination process in infants aged 0 to 1 year is by looking at motor development, such as when the baby should be able to own but have not been able to stomach, then this means that there is interference with its development.
