Neuroplasticity refers to structural and functional changes in the brain or central nervous system that are brought about by training and experience. The brain is the organ that is designed to change in response to experience; it is naturally adaptive in order to deal with the constant change within and around us.

Neuroscience and psychological research over the past decade on this topic has burgeoned and is leading to new insights about the many ways in which the brain, behavior, and experience change in response to experience. This basic issue is being studied at many different levels, in different species, and on different time scales. Yet all of the work invariably leads to the conclusion that the brain is not static but rather is dynamically changing and undergoes such changes throughout one’s entire life.

Research on structural plasticity is beginning to reveal how the literal composition of the adult mammalian brain is constantly changing in response to experience.
