Which term describes the brain's ability to adapt its circuitry in response to activity patterns?

• A. Constancy
• B. Plasticity
• C. Rigidity
• D. Deterioration

Answer: (B)

Plasticity describes the brain's ability to adapt its circuitry in response to activity patterns. This means neural connections can strengthen or weaken based on use, learning, or after injury, allowing skills to be acquired and functions to shift as needed. Repeated practice can enhance synaptic efficiency and even recruit different regions to take over tasks, reflecting how the brain reorganizes itself with experience. The other terms suggest no change or decline—constancy implies staying the same, rigidity implies inflexibility, and deterioration implies worsening function—none of which capture the brain’s capacity to remodel itself through activity.
