It can grow new cells. It can enhance cell size or cell activity. It can prune away pathways that are no longer used, a process known as neural sculpting. And it can forge new relations between entire networks of cells; this is called connectivity. These cellular changes occur in service to getting better at what we practice—in this case, playing the piano. We practice other things, too, some of them not so harmless. Neuroplasticity is also a social construct. It evokes the way communities shape themselves through practice. We change or stay the same because of and in relation to one another. Think of the …
