Which scenario provides evidence for brain plasticity in humans?

Which scenario provides evidence for brain plasticity in humans?

• A. A brain that never changes after birth
• B. A brain that cannot recover after injury
• C. Reorganization of neural connections following training or injury
• D. No changes in neural networks despite learning

Answer: (C)

Brain plasticity is the brain’s ability to change its structure and connections in response to experience, learning, or injury. The scenario that provides evidence for this is when neural connections reorganize after training or after injury. This shows that practice can reshape how brain networks are wired, strengthening relevant pathways to improve performance, and that the brain can adapt by rerouting functions when some areas are damaged. Other options describe a lack of change—brains that never adapt, or that cannot recover after injury, or that learning doesn’t alter networks—which would not reflect plasticity. The key idea is that the brain actually rewires itself in response to experience or damage, which is exactly what this option conveys.
