The concept of 'neuroplasticity' has revolutionized our understanding of the brain's capacity for change. Historically, scientists believed that the adult brain was largely fixed, with neural circuits becoming immutable after a critical period in childhood. However, recent research demonstrates that the brain remains highly adaptable throughout life, constantly reorganizing its structure and function in response to experience. This plasticity is evident in learning new skills, recovering from brain injuries, and even in adapting to sensory loss, such as when a person loses sight and the visual cortex is repurposed for processing touch or sound. While this adaptability offers immense potential for rehabilitation, it also underscores the brain's vulnerability to maladaptive changes, such as chronic pain or addiction, where neural pathways become entrenched in harmful patterns. Thus, neuroplasticity is a double-edged sword, reflecting both the brain's resilience and its susceptibility to environmental influences.
❓ According to the passage, what is the main implication of neuroplasticity for the adult brain?

C. C. Neuroplasticity only occurs in response to severe injuries.
D. D. The visual cortex always processes visual information throughout life.
✅ 正确答案
B. The brain can reorganize itself, which can be both beneficial and harmful.
