The concept of 'neuroplasticity' has revolutionized our understanding of the brain's capacity for change. Historically, it was believed that the adult brain was relatively fixed after a critical period in childhood. However, recent research demonstrates that neural pathways can be remodeled throughout life in response to learning, experience, and even injury. This adaptability is underpinned by mechanisms such as synaptic strengthening and the generation of new neurons in the hippocampus. Neuroplasticity has significant implications for rehabilitation after stroke, as well as for educational practices that leverage the brain's malleability. Yet, the extent of plasticity varies with age and is influenced by factors like stress and environmental enrichment. 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 completely unable to change after childhood.
B. Stroke rehabilitation can benefit from the brain's ability to reorganize itself.
C. Neuroplasticity is uniform across all ages and conditions.
D. The generation of new neurons occurs only in the cerebral cortex.
✅ 正确答案
Stroke rehabilitation can benefit from the brain's ability to reorganize itself.
