What is neuroplasticity?

• A. A decline in neural plasticity with age.
• B. The nervous system's ability to reorganize its structure and function.
• C. The process of forming new motor units.
• D. A temporary failure of synaptic transmission.

Answer: (B)

Neuroplasticity is the nervous system’s ability to reorganize its structure and function in response to experience, learning, or injury. This means neural connections can strengthen or weaken, new synapses can form, and brain regions can shift or adapt their roles to support new skills or recover lost function after damage. For example, practicing a new instrument strengthens the relevant neural circuits; after a stroke, other pathways can take over tasks that were once served by damaged areas. The other ideas don’t capture this adaptive reorganization. A decline in plasticity with age describes a trend rather than the defining capacity, and neuroplasticity can persist and adapt across life, though it may change in magnitude. Forming new motor units is a more specific motor-neural process, not the general ability to reorganize the brain’s structure and connections. A temporary failure of synaptic transmission describes a disruption, not the brain’s capability to reorganize itself.
