Plasticity in the nervous system refers to the brain's ability to

• A. Increase neuron size
• B. Change in response to experience
• C. Decrease synaptic connections
• D. Delay development

Answer: (B)

Plasticity is the nervous system's ability to change in response to experience. When you learn a skill or recover from brain injury, neural circuits can become stronger or weaker, new connections can form, and existing networks can reorganize. This flexibility underlies learning, memory, and adaptation to new situations. The option that describes the brain changing in response to experience best captures this concept. Increasing neuron size isn’t the defining feature of plasticity, and while synaptic connections can decrease in some contexts, plasticity encompasses both strengthening and reorganization of connections driven by activity, not just a simple reduction. Delaying development relates to maturation timing, not the activity-driven remodeling of neural circuits.
