Final answer:
Neuroplasticity is the ability of the brain to change and adapt. Examples of neuroplasticity include the reorganization of neurons in blind individuals to enhance touch, the development of language in babies with stroke through intense verbal stimulation, and the ongoing process of forming new synapses throughout life. The growth of the myelin sheath, however, is completed at an early stage in life. Option d.
Step-by-step explanation:
Neuroplasticity refers to how the nervous system can change and adapt. One of the examples of neuroplasticity is the ability of neurons programmed for vision to be taken over to enhance touch in individuals who are blind from birth. This is evidence that the brain is capable of adapting and changing through neuroplasticity. Another example of neuroplasticity is the development of language in babies who have a stroke in the language areas of the brain. With intense verbal stimulation, language can develop normally, indicating the plasticity of the brain in response to injury. Synaptogenesis, which is the formation of new synapses, occurs throughout life, allowing us to continue learning new things at any age. However, the growth of the myelin sheath, which insulates and speeds up the conduction of nerve impulses, is completed at a relatively early stage in life and does not continue until very late in life.
