The concept of neuroplasticity has revolutionized our understanding of the human brain. Previously, scientists believed that the adult brain was fixed and immutable after a critical period in childhood. However, recent research demonstrates that the brain remains capable of reorganizing its structure and function throughout life in response to experience, learning, and even injury. This adaptability is underpinned by mechanisms such as synaptic strengthening, the formation of new neural connections, and, in certain regions like the hippocampus, the generation of new neurons. Neuroplasticity has significant implications for rehabilitation after stroke, where targeted therapies can promote functional recovery by encouraging the brain to reroute functions from damaged areas to healthy ones. Moreover, it challenges traditional educational practices, suggesting that lifelong learning is not merely an academic ideal but a biological reality. Nevertheless, the extent of plasticity varies with age, and certain types of learning become more difficult as we grow older, highlighting the importance of early intervention in developmental disorders.
❓ According to the passage, which of the following statements best reflects the main implication of neuroplasticity?
A. The adult brain is completely unable to change, so rehabilitation after injury is futile.
B. The brain's ability to reorganize supports recovery and lifelong learning, though its degree diminishes with age.
C. Neuroplasticity only occurs during childhood, making early education the sole factor in brain development.
D. New neurons are generated only in the cortex, enabling unlimited cognitive enhancement at any age.
✅ 正确答案
The brain's ability to reorganize supports recovery and lifelong learning, though its degree diminishes with age.
