The concept of neuroplasticity has revolutionized our understanding of the human brain. Historically, scientists believed that the adult brain was largely fixed, with neural circuits becoming immutable 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 even injury. For instance, individuals who lose their sight often exhibit enhanced auditory or tactile processing, as the visual cortex is recruited for other sensory functions. Such findings have profound implications for rehabilitation, suggesting that targeted training can harness plasticity to recover lost functions. Nevertheless, plasticity is not unlimited; it diminishes with age and is influenced by genetic and environmental factors. Understanding these constraints is crucial for developing effective therapeutic interventions.
❓ According to the passage, what is a key implication of neuroplasticity?
A. The adult brain is structurally unchangeable after childhood.
B. Brain reorganization can occur only during early development.
C. Training may help restore abilities by leveraging brain adaptability.
D. Sensory loss permanently prevents any functional compensation.
✅ 正确答案
Training may help restore abilities by leveraging brain adaptability.
