Neuroplasticity is most active in childhood as a part of normal human development, and can also be seen as an especially important mechanism for children in terms of risk and resiliency. Trauma is considered a great risk as it negatively affects many areas of the brain and puts a strain on the sympathetic nervous system from constant activation. Trauma thus alters the brain’s connections such that children who have experienced trauma may be hyper vigilant or overly aroused. However a child’s brain can cope with these adverse effects through the actions of neuroplasticity.
There are many examples of neuroplasticity in human development. In an article written by Justine Ker and Stephen Nelson, the effects of musical training on neuroplasticity is looked at. Musical training is a form of experience dependent plasticity. This is when changes in the brain occur based on experiences that are unique to an individual. Examples of this are learning multiple languages, playing a sport, doing theatre, etc. A study done by Hyde in 2009, showed that changes in the brain of children could be seen in as little as 15 months of musical training. Ker and Nelson suggest this degree of plasticity in the brain’s of children can “help provide a form of intervention for children… with developmental disorders and neurological diseases.”
