Neuroplasticity:

This is the ability of neural networks in the brain to change through growth and reorganization. It's like how a city can adapt and reroute traffic when there's a roadblock.

Stroke:

This is a medical condition where poor blood flow to the brain results in cell death. It's similar to a power outage in our city analogy - without electricity (or blood flow), parts of the city (brain) can't function.

Tumor: This is an abnormal growth of cells within the brain, which can cause lesions. Like an unplanned skyscraper popping up in our city, it disrupts normal functions and pathways.
