Abstract
Neuroplasticity can be defined as brain’s ability to change, remodel and
reorganize for purpose of better ability to adapt to new situations. Despite the fact that the concept of neuroplasticity is quite new, it is one of the most important discoveries in neuroscience. The fact is that neural networks are not fixed, but occurring and disappearing dynamically throughout our whole life, depending on experiences. While we repeatedly practice one activity such as a sequence of movements or a mathematical problem, neuronal circuits are being formed, leading to better ability to perform the practiced task with less waste of energy. Once we stop practicing a certain activity, the brain
will redirect these neuronal circuits by a much known ‘use it or lose it’
principle. Neuroplasticity leads to many different occurrences, such as habituation, sensitization to a certain position, medication tolerance, even recovery following brain injury.
