Which statement about plasticity is most accurate?

• A. It occurs only during early development
• B. It is impossible to observe in humans
• C. It requires genetic modification
• D. It can occur across the lifespan and be driven by experience

Answer: (D)

Plasticity is the brain’s ability to reorganize itself by forming new connections in response to experience, learning, or injury. The statement that best captures this idea is that plasticity can occur across the lifespan and be driven by experience. Although plasticity is especially robust during early development, the brain remains capable of reorganization throughout life. This means you can learn new skills, адапt to new environments, or recover functions after injury even as an adult, though the rate and extent of change can vary. Changes come from activity-dependent processes, like strengthening or weakening synapses, forming new connections, or reallocating neural resources to different tasks. You don’t need to modify genes to see these changes; experiences and practice are sufficient to drive neural remodeling. In contrast, the view that plasticity happens only early in life isn’t accurate, since adults show meaningful, experience-driven changes too. And the idea that plasticity cannot be observed in humans isn’t true, given plenty of evidence from learning studies, rehabilitation after brain injury, and neuroimaging findings. Similarly, plasticity does not require genetic modification; it arises from how the brain uses and reorganizes its existing networks in response to activity.
