The following text describes Neuroplasticity. For decades, neurobiology subscribed to the dogma that the adult brain was fixed and immutable. However, the discovery of neuroplasticity upturned this view, demonstrating that the brain's neural networks constantly reorganize themselves throughout life. This plasticity occurs on multiple levels, from cellular changes (increasing synaptic strength) to cortical remapping (where functions of a damaged brain region are assumed by another). Thus, the brain is not a static organ but a dynamic process reshaped by experience.
