Detailed explanation-1: -Myelination is a developmental process that begins during the end of gestation, intensifies after birth over the first years of life, and continues well into adolescence.
Detailed explanation-2: -Myelination (the coating or covering of axons with myelin) begins around birth and is most rapid in the first 2 years but continues perhaps as late as 30 years of age. Synaptic development is a more complicated issue.
Detailed explanation-3: -These studies have also shown that teens have less white matter (myelin) in the frontal lobes compared to adults, and that myelin in the frontal lobes increases throughout adolescence. With more myelin comes the growth of important neurocircuitry, allowing for better flow of information between brain regions.
Detailed explanation-4: -Myelination in the human CNS begins 1 to 2 months prior to birth in the visual system and extends to the other sensory systems over the first year of life.
