Plasticity is most evident in brain reorganization following damage in which group?

• A. Adults
• B. Elderly
• C. Children
• D. Infants

Answer: (C)

Plasticity—the brain’s capacity to reorganize itself after damage or experience—is strongest during development. In children, neural networks are still forming as language, motor, and cognitive systems are maturing, so other brain areas can often take over functions that were damaged. This makes observable reorganization after injury particularly evident in this group, because the system remains flexible and can reroute functions as it learns. In adults, circuits are more fixed and compensatory changes are more limited, and in elderly individuals plasticity tends to decline further. Infants also show high plasticity, but in many contexts the notable reorganization is most evident once children have progressed through early development, hence the emphasis on children.
