strength of the connections between neurons (or synapses) changes.
neuroplasticity and neurogenesis
Neuroplasticity refers to the brain’s ability to adapt
When we learn something new, we create new connections between our neurons.
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
Our brains are truly extraordinary; unlike computers, which are built to certain specifications and receive software updates periodically, our brains can actually 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 on a daily basis, but it’s also something that we can encourage and stimulate.
it was discovered that neurons could reorganize after a traumatic event. Further research found that stress can change not only the functions but also the structure of the brain itself
Although related, neuroplasticity and neurogenesis are two different concepts.
Neuroplasticity is the ability of the brain to form new connections and pathways and change how its circuits are wired; neurogenesis is the even more amazing ability of the brain to grow new neurons
- Neuroplasticity is one fundamental process that describes any change in final neural activity or behavioral response, or;
- Neuroplasticity is an umbrella term for a vast collection of different brain change and adaptation phenomena.
