What does neuroplasticity refer to?

Neuroplasticity refers to the brain's remarkable capacity to form new connections among neurons and reorganize existing pathways in response to learning, experience, or injury. This adaptive characteristic allows the brain to modify its structure and function over time, facilitating recovery from trauma and enhancing cognitive abilities. It plays a critical role in various developmental processes, including learning new skills and adapting to new environments.

The concept encompasses both the strengthening of existing neural pathways and the creation of new ones, which is fundamental to our ability to learn and adapt throughout life. This dynamic quality of the brain is what makes option A the most accurate description of neuroplasticity.
