Neuroscience has changed considerably in the past 20 years. An example of change over period is the concept of brain plasticity. Brain plasticity refers to the brain’s ability to rewire itself, relocating information processing functions to different brain areas and/or neural networks. Two decades ago, it was believed that brain networks were static after its initial formation period. Now that belief has changed. The study of brain plasticity has profound implications in human learning and behaviour, and as such, for mental health. To better understand this concept, let’s take a quick tour of the human brain, neural networks, and the plastic potential therein.
