This is an example of how the experiences we have shape the way our brains process information. The more often we do something, like practice an instrument, the stronger our brain responses tend to be. Practice might not make perfect, but it does shape how our brains process information. At a microscopic level, it even changes how neurons in our brains are connected to each other. This ability to change the microstructure of our brains is called neuroplasticity. Neuroplasticity is what allows us to learn new things throughout our lives.
