Final answer:
Neuroplasticity refers to the brain's ability to change and adapt to environmental change and injury by creating new synapses, pruning unused synapses, and even the birth of new neurons.
Step-by-step explanation:
Neuroplasticity refers to the brain's ability to change, both physically and chemically, to enhance its adaptability to environmental change and compensate for injury. It involves processes such as the creation of new synapses, pruning of unused synapses, changes in glial cells, and even the birth of new neurons. Neuroplasticity allows our brains to constantly change and adapt throughout our lives.
