The concept of neuroplasticity has revolutionized our understanding of the human brain. Previously, scientists believed that the adult brain was structurally fixed after a critical period in childhood. However, recent research demonstrates that the brain remains capable of substantial reorganization throughout life, adapting to new experiences, learning, and even injury. This adaptability is underpinned by synaptic strengthening and the formation of new neural pathways. For instance, individuals who lose their sight often exhibit heightened auditory or tactile processing, as brain regions originally dedicated to vision are recruited for other senses. While the mechanisms are complex, neuroplasticity offers promising avenues for rehabilitation after stroke or traumatic brain injury. Nevertheless, the extent of plasticity varies with age and is influenced by factors such as environmental enrichment and stress, highlighting that the brain's malleability is not unlimited but context-dependent.
❓ According to the passage, what is the main implication of neuroplasticity for medical treatment?
A. A. It proves that brain damage is always reversible.
B. B. It suggests that rehabilitation after brain injury can be enhanced.
C. C. It indicates that the adult brain cannot change after childhood.
D. D. It shows that sensory loss automatically improves other senses.
✅ 正确答案
B. It suggests that rehabilitation after brain injury can be enhanced.
