Which statement best defines brain plasticity?

• A. The brain's ability to be shaped by experience.
• B. The brain's fixed wiring.
• C. The brain's immune function.
• D. The brain's ability to store memories.

Answer: (A)

Brain plasticity is the brain’s capacity to change its structure and function in response to experiences, learning, and environmental input. This means neural connections can be strengthened or weakened, new connections can form, and sometimes different brain regions can take over tasks if needed. The statement that the brain’s ability to be shaped by experience best captures this concept because plasticity is driven by experience and use, not by a fixed design. Examples include how practice refines skills and how recovery after injury involves reorganization of neural networks. The other ideas describe static wiring, immune functions, or simply the outcome of memory storage, but they don’t convey the ongoing, experience-driven adaptability that plasticity encompasses.
