Does experience change the actual structure of the brain?
The answer is yes. Brain development is activity-dependent. Like computer circuits, neural circuits process information through the flow of electricity. However, the circuits in our brains are much more flexible. Every experience, such as reading a book, riding a bicycle, sharing a story, excites certain neural circuits and leaves others inactive. Those that are consistently used will be strengthened, while the others may be dropped away. This is called “pruning”, which benefits neural processing, making the circuits work more quickly and efficiently.
Yes. Brain development is “activity-dependent,” meaning that the electrical activity in every circuit—sensory, motor, emotional, cognitive–shapes the way that circuit gets put together. Like computer circuits, neural circuits process information through the flow of electricity. Unlike computer circuits, however, the circuits in our brains are not fixed structures. Every experience–whether it is seeing one’s first rainbow, riding a bicycle, reading a book, sharing a joke–excites certain neural circuits and leaves others inactive. Those that are consistently turned on over time will be strengthened, while those that are rarely excited may be dropped away. Or, as neuroscientists sometimes say, “Cells that fire together, wire together.” The elimination of unused neural circuits, also referred to as “pruning,” may sound harsh, but it is generally a good thing. It streamlines children’s neural processing, making the remaining circuits work more quickly and efficiently. Without synaptic pr
