Which statement best defines brain plasticity?

• A. The brain's fixed wiring.
• B. The brain's immune function.
• C. The brain's capacity for memory storage.
• D. The brain's ability to be shaped by experience.

Answer: (D)

Brain plasticity is the brain's ability to be shaped by experience. It means neural connections can grow, weaken, or reorganize in response to learning, practice, or injury, allowing functions to shift to different networks as needed. This adaptability underlies skill learning, recovery after damage, and everyday changes in thinking and behavior. The idea that the brain has fixed wiring is the opposite of plasticity. Immune function is unrelated to how neural circuits adapt, and memory storage describes how we hold information rather than the brain’s capacity to change itself.
