The answer would be synaptic pruning.
The brain in children will have a much more synaptic connection than adults. This connection is important for learning process in the early stage of life. More synaptic connections allow multiple parts the brain areas to be connected even if there is a damage in one area.
The synapse will be cut down later in a process called synaptic pruning. Only the area that frequently used will be preserved.

Let me explain something that can make you easily understand ok?
So as you know, humans has 46 chromosomes right?
Also, you know that when a gamete is formed there are 2 cell infused to form that 46 chromosomes. (The human cell and sperm)
IF the cells has 46 chromosomes each and it infused with another 46 chromosomes then the total will be 92 chromosomes and not 46 chromosomes. That's why the cell produced only has 23 chromosomes which is fewer so that when it form a genetic material, the total chromosomes will be 46 chromosomes.
Sorry if my english sucks, hope you understand REEEEE
you Are welcome
