Neuroplasticity refers specifically to the brain's ability to form new neural connections throughout a person's life. This concept highlights the dynamic nature of the brain, which allows it to adapt in response to new experiences, learning, or injury. The brain is not a static organ; rather, it is continuously reorganizing itself by creating and strengthening synaptic connections and pathways.

This adaptability is crucial for learning and memory, as it enables individuals to acquire new skills and adjust their thinking in response to challenges. For instance, if one area of the brain is damaged, neuroplasticity allows other areas to take over some of the lost functions, illustrating the brain's resilience and ability to compensate for changes.

Other options present ideas that do not accurately encapsulate the multifaceted nature of neuroplasticity. The notion that the brain grows in size with age suggests a physical growth aspect instead of the functional reorganization that neuroplasticity represents. Similarly, rigidity of neural pathways contradicts the idea of flexibility inherent in neuroplasticity. Lastly, the process of forgetting information does not align with neuroplasticity, as it focuses on connection formation rather than disconnection or loss of neural associations.
