Structural plasticity refers to the brain's ability to change its physical structure in response to learning, experience, or environmental factors. This adaptability allows neurons to form new connections or strengthen existing ones, enhancing cognitive functions and memory. This process is crucial for recovery from injuries and adapting to new challenges. For example, when a person learns a new skill, such as playing a musical instrument, their brain undergoes structural changes that support improved performance. Overall, structural plasticity is a fundamental aspect of how the brain remains flexible and responsive throughout life.
