The concept of 'neuroplasticity' has revolutionized our understanding of the human brain. Contrary to the long-held belief that the adult brain is hard-wired and immutable, research now demonstrates that neural pathways can be reorganised throughout life in response to learning, experience, or injury. This adaptability occurs at multiple levels, from cellular changes in synaptic strength to large-scale cortical remapping. For instance, studies on individuals who have lost a limb show that the corresponding sensory cortex area can become responsive to stimulation from adjacent body parts. Such findings have profound implications for rehabilitation and education, suggesting that targeted interventions can harness plasticity to promote recovery or enhance cognitive skills. However, plasticity is not always beneficial; it can also underpin maladaptive changes, such as chronic pain or phantom limb sensations. Thus, understanding the precise conditions that facilitate adaptive versus maladaptive plasticity remains a key challenge in neuroscience.
❓ According to the passage, what is a significant implication of neuroplasticity?
A. The adult brain is largely unchangeable after a certain age.
B. Rehabilitation can potentially use the brain's adaptability to aid recovery.
C. Plasticity only occurs in response to injury, not in normal learning.
D. All changes in neural pathways are always beneficial for the individual.
✅ 正确答案
Rehabilitation can potentially use the brain's adaptability to aid recovery.
