Which statement best describes neuroplasticity in relation to environmental enrichment?

• A. Neuroplasticity only occurs in childhood.
• B. It is unaffected by environment.
• C. Experience can lead to structural changes in the brain, such as cortical thickness and synaptic density.
• D. It is only about functional changes, not structure.

Answer: (C)

Neuroplasticity is the brain’s ability to reorganize its structure and connections in response to experience. Environmental enrichment provides more sensory, cognitive, and social stimulation, which can drive the brain to form new connections and strengthen existing ones. This leads to observable structural changes, such as increased cortical thickness and higher synaptic density in relevant areas. While neuroplasticity also involves functional changes—like more efficient neural signaling—the point here is that experience can alter the brain’s physical architecture, not just its activity. It’s also important to note that plasticity isn’t confined to childhood; it occurs across the lifespan, especially with rich environmental input.
