Our brains are truly amazing, aren't they?
Have you ever watched one of those specials on someone who experienced an amazing, unexpected recovery after a traumatic brain injury, stroke, or other brain damage? Some of those stories seem like the only explanation is magic.
Although it certainly seems inexplicable, scientists have been hard at work studying exactly these cases over the last several decades, and have found the explanation behind the magic: neuroplasticity. Our brains are truly extraordinary; unlike computers, which are built to certain specifications and receive software updates periodically, our brains can receive hardware updates in addition to software updates. Different pathways form and fall dormant, are created, and are discarded, according to our experiences.
When we learn something new, we create new connections between our neurons. We rewire our brains to adapt to new circumstances. This happens daily, but it's also something that we can encourage and stimulate.
