The concept of 'neuroplasticity' has revolutionized our understanding of the human brain. Historically, scientists believed that the adult brain was largely fixed in structure and function after a critical period in childhood. However, recent research demonstrates that the brain retains a remarkable ability to reorganize itself throughout life. This adaptability occurs at multiple levels, from cellular changes in synaptic strength to large-scale cortical remapping. For instance, individuals who lose their sight often exhibit enhanced auditory or tactile processing, as brain regions normally devoted to vision are recruited for other senses. Such findings have profound implications for rehabilitation after brain injury, suggesting that targeted therapies can harness plasticity to promote recovery. Nevertheless, plasticity is not unlimited; its extent depends on factors such as age, the nature of the injury, and the intensity of training.
❓ According to the passage, what is the main implication of neuroplasticity for brain injury rehabilitation?
A. The adult brain is completely fixed and cannot adapt after injury.
B. Targeted therapies may be able to utilize the brain's adaptability to aid recovery.
C. Sensory loss in one modality always leads to enhanced abilities in others.
D. Plasticity is unlimited and occurs equally at all ages.
✅ 正确答案
Targeted therapies may be able to utilize the brain's adaptability to aid recovery.
