The concept of neuroplasticity has revolutionized our understanding of the human brain. Historically, scientists believed that the adult brain was structurally fixed after a critical period in childhood. However, recent research demonstrates that the brain retains a remarkable capacity for reorganization throughout life. This adaptability is driven by synaptic strengthening and the formation of new neural pathways in response to learning, experience, or injury. For instance, individuals who lose their sight often show enhanced auditory or tactile processing, as the brain reallocates cortical resources. Such findings have profound implications for rehabilitation, suggesting that targeted training could help stroke victims regain lost functions by rewiring undamaged areas. Nevertheless, neuroplasticity is not limitless; its extent diminishes with age and depends on factors like motivation and the intensity of stimulation. Thus, while the brain is far more malleable than once thought, its plasticity operates within biological constraints.

A. It only occurs in childhood.
B. It is unaffected by personal effort.
C. It decreases with age and requires certain conditions.
D. It cannot help with sensory loss.
✅ 正确答案
It decreases with age and requires certain conditions.
