The concept of 'neuroplasticity' has revolutionized our understanding of the human brain. Previously, it was believed that the adult brain was largely fixed in its structure and function after a critical period in childhood. However, recent research demonstrates that the brain remains capable of significant reorganization throughout life, adapting to new experiences, learning, and even injury. This plasticity occurs at multiple levels, from synaptic connections between neurons to entire cortical maps. For instance, individuals who lose their sight often exhibit enhanced auditory or tactile processing, as the visual cortex is recruited for other sensory modalities. Furthermore, neuroplasticity underpins the effectiveness of rehabilitation after stroke, where targeted therapy can help reroute functions to undamaged brain regions. This dynamic view challenges the old paradigm and holds profound implications for education, mental health treatment, and cognitive enhancement.
❓ According to the passage, which of the following statements best reflects the main idea?
A. A) The adult brain is structurally fixed and cannot change after childhood.
B. B) Neuroplasticity allows the brain to adapt, learn, and recover by reorganizing its structure and function.
C. C) Loss of sight inevitably leads to enhanced hearing and touch in all individuals.
D. D) Rehabilitation after stroke is ineffective because the brain cannot reroute functions.
✅ 正确答案
B) Neuroplasticity allows the brain to adapt, learn, and recover by reorganizing its structure and function.
