Brain Facts # 5
Lifelong Neuroplasticity
Historically, it was thought that the human brain was a fixed and essentially limited system that only degraded with age. This view saw the brain as a rigid machine in many ways, pretty much set after childhood. By contrast, we have now come to appreciate that the human brain is actually a highly dynamic and constantly reorganizing system, capable of being shaped and reshaped across the entire lifespan. It is believed that every experience alters the brain’s organization at some level. The central concept in this new approach is neuroplasticity, the brain’s lifelong capacity to change and rewire itself in response to the stimulation of learning and experience. This includes both the lifelong ability to create new neurons and to create new connections between neurons .
A young brain allows for fast learning, as well as for potentially faster repair. As we age, the rate of neuroplasticity declines, but does not come to a halt. As the noted neuroscientist, Dr. James Zull puts it: “We now know that every brain can change, at any age. There is really no upper limit on learning since the neurons seem to be capable of growing new connections whenever they are used repeatedly.”
Lifelong neuroplasticity has major consequences for brain health and fitness. It means that our lifestyle and actions play a meaningful role in how brains physically change throughout life. Neuroplasticity gives us the power to resist the effects of decline or disease by supporting our ability to accumulate knowledge and experiences.
CLASSROOM & HOMEWORK TIP for SPECIAL NEEDS CHILDREN
Once children are in school, adults tend to be preoccupied with whether they are learning their alphabet and arithmetic. But if a child is having learning difficulties, the first thing we need to look at is not his letters and numbers but his ability to pay attention and to regulate himself. If a child doesn’t have this ability, then we need to work on that ability with the child. You cannot jump over this vital internal milestone. There is no point in pushing a child to learn how to spell triangle or add 15 + 27 before he learns how to look, listen and stay calm. First things first.
