Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections throughout life. This adaptability allows the brain to adjust to new experiences, learn new information, and recover from injuries. Neuroplasticity can occur at multiple levels, including cellular changes and long-term potentiation in synapses. This concept underscores the importance of environmental factors and experiences in shaping brain function and highlights potential therapeutic strategies for conditions like stroke and neurodegenerative diseases.
