Experience and learning change the 'architecture' of the brain by:

• A. Reducing neural connections.
• B. Forming new synapses and strengthening existing ones.
• C. Not changing structure.
• D. Erasing memories.

Answer: (B)

Learning reshapes how neurons connect and talk to each other through neuroplasticity. When you practice a skill or form a memory, the brain grows new synapses and strengthens existing connections, making those neural pathways more efficient and reliable. This formation of new connections and the strengthening of active ones is what changes the brain’s architecture with experience. While some pruning of unused connections can occur, the key change driven by learning is not a simple reduction in connections but the growth and reinforcement of networks that support the new information or skill. Erasing memories doesn’t explain how learning alters structure; memories are encoded by strengthened pathways, not erased.
