Neuronal plasticity refers to the ability of the brain's neurons to change and adapt in response to experience, environmental factors, or injury. This phenomenon is fundamental to learning, memory, and recovery from brain damage. Neuronal plasticity encompasses various processes, including synaptic plasticity (changes in the strength and structure of connections between neurons), neurogenesis (the formation of new neurons), and circuit reorganization. Research in this area seeks to understand the mechanisms underlying neuronal plasticity and how it can be manipulated to enhance cognitive function, treat neurological disorders, and promote brain repair and recovery.
