What is brain plasticity? How can this plasticity help blind people?

What will be an ideal response?

A good answer will include the following key points:
• Plasticity is the brain's ability to change and adapt in response to experience.
• Plasticity happens through neurogenesis or by reorganizing or growing new neural connections.
• Plasticity is also apparent in some people who have been blind or deaf from birth or early childhood.
• In the period of rapid development after birth, connections form between the eyes and the visual cortex, and between the ears and the auditory cortex—but also between the eyes and the auditory cortex, and the ears and the visual cortex.
