With brain patterns, these questions may come to mind: How long have they been there? It is a brain pattern that existed (or that was established) during childhood as the brain develops? Was it present at birth? Can it be changed?
When Dr. Davidson did research on day-old infants, in the experiments he found that even at birth, there were clear individual differences and left/right asymmetry in terms of activation. Everyone’s genetic makeup is different, but the big question is do these differences persist? Dr. Davidson helped discover that what you are born with is not necessarily what you are dealt with as the brain and behavior can change.
Neuroplasticity is the idea that the brain can change – either for better or worse. The brain has the ability to change in both structure and function. Consider learning and memory – these are constant examples of how our brains are able to change form. When you learn something new and also when a new experience enters your memory, this is the brain changing – expanding and retaining.
Brain structure and function can change in response to two forces:
- The life you lead
- Thinking yourself into a different brain
The life you lead, meaning the experiences you have – physical as well as emotional or mental – are signals from the outside world. This is similar to your brain collecting memories and learning new information. The other way the brain can change structure and function is in response to purely mental activity. This is similar to the brain emotional style of outlook. Higher left activity is associated with a more positive outlook; higher right activity is associated with more negative outlook. To change the brain grooves, you can think yourself into a different brain by working on a more positive outlook (or negative, as the door does swing both ways).
