How old is neonatal cerebellum development?
summary
If you want to raise a smart baby, you need to build a developed brain for him. If we want to tap the potential of infants, we need to understand the development process of the brain: the brain is the headquarters of the human body, it determines everything.
How old is neonatal cerebellum development?
The first stage, from pregnancy to birth. This stage is what we call the long brain stage. By the time babies are born, the brain already has about 10-18 billion brain cells, close to that of adults. That is to say, from pregnancy to birth, the number of brain cells has grown well.
In the second stage, after the baby is born, the brain will enter a period of long mass, and the volume of brain cells and many other things will grow up. After birth, "synapses" connected by nerve cells begin to form. The number of synapses reaches the peak at three months. At three months, the deposition of gray matter fat is completed. At six months, the increase of DNA content stops. At 12 months, oligodendrocytes reach 70% of adults. At 3 years old, the cerebellum is basically mature. At 3-4 years old, the myelination of nerve is basically completed.
The myelin sheath of nerve fiber is like the insulation layer of wire, which can make neurons transmit information accurately with high speed, clear division of labor and higher efficiency. At the time of birth, myelination of nerve fibers is very few, and nerve fibers are very short, very few. At the age of 3-4, myelination of nerve fibers is completed.
matters needing attention
The experience of 0-3 years old has a great influence on the development of neural network. The stimulation of synapses and the use of high frequency are conducive to the development of intelligence. Three months after birth, there are so many synapses. Why only 500 trillion survive? Because of the lack of use! To use some methods to make the synapse active, then that synapse can survive. If not used enough or not used enough, the number of synapses will be less.
