What effect does increased myelination have on the child's abilities?
What will be an ideal response?
Myelination is the process by which nerve cells are covered and insulated with a layer of fat cells. Myelination increases the speed and efficiency of information traveling through the nervous system. It is important in the development of a number of children's abilities. For example, myelination in the areas of the brain related to hand-eye coordination is not complete until about 4 years of age. Myelination in the areas of the brain related to focusing attention is not complete until the end of the middle childhood years or later. This is reflected in the fact that young children's abilities in these areas are underdeveloped. A study of children (mean age: 4 years) found that children with developmental delay of motor and cognitive milestones had significantly reduced levels of myelination.
