Plasticity refers to the ability of a material to change its shape or structure without breaking. In the context of biology, it describes how the brain and nervous system can adapt and reorganize themselves in response to new experiences, learning, or injury. This adaptability is crucial for recovery and development throughout life. In psychology, plasticity can also refer to the capacity of the mind to adjust to new information or environments. For example, when learning a new skill, such as playing a musical instrument, the brain forms new connections, demonstrating its plastic nature. This concept is essential for understanding how we learn and grow.
