Lendio Neuroscientific dogma up until about ten years ago was that past a certain point in our lives, our brain did not change, we had what we had, and that was it. In fact, any change would be that it shrank, actually, as neurons died. But that dogma has been overturned. Our brains are constantly trying out new connections. Each neuron has branches which are connecting with other neurons based on what we are learning in the moment.

Those connections can be kept, and form what is called a cognitive reserve, which can reroute signals around trouble spots in an aging brain, for example. Here is how neuroplasticity is described in a review of Sharon Begley's book, Train Your Mind, Change Your Brain, from the Mindfulness Institute.
