The concept of neuroplasticity has revolutionized our understanding of the human brain. Historically, scientists believed that the adult brain was structurally 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, the formation of new neural connections, and even the generation of neurons in specific regions like the hippocampus. Such changes are most pronounced in response to learning, environmental enrichment, and recovery from injury. For instance, individuals who lose their sight often show enhanced tactile and auditory processing, as the visual cortex is recruited for other sensory modalities. While the extent of plasticity diminishes with age, it never ceases entirely. This finding has profound implications for rehabilitation and education, suggesting that targeted interventions can harness the brain's inherent flexibility to improve cognitive function and motor skills.
❓ According to the passage, which of the following statements best reflects the current understanding of neuroplasticity?
A. The adult brain is largely unchangeable after childhood.
B. Neuroplasticity occurs only in response to severe brain injury.
C. The brain can reorganize itself throughout life, although the capacity may decline with age.
D. Visual cortex activity is permanently fixed and cannot be altered by sensory loss.
✅ 正确答案
The brain can reorganize itself throughout life, although the capacity may decline with age.
