Can our experiences change our brain

A. It is now know by Scientists that brain is remarkably "plastic:" it continues to change during the course of life in accordance with our experiences. It's also clear that our surroundings affect our experiences, to a large degree driving our thinking and behavior as we adapt to our environment. Our brain, in return, reflects our behavior, as behaviors are sum total of patterns of neural activation. Essentially, then, behavior, brain, and environment are all intricately linked in an interactive loop: changes in environment result in changes in behavior which lead to changes in brain.
