The concept of neuroplasticity has revolutionized our understanding of the brain's capacity for change. Historically, scientists believed that the adult brain was relatively fixed, with neural circuits becoming rigid after a critical period in childhood. However, recent research demonstrates that the brain remains malleable throughout life, continuously reorganizing its structure and function in response to experience. This adaptability is most pronounced in learning and memory, where synaptic connections are strengthened or pruned based on activity. Moreover, neuroplasticity plays a crucial role in recovery from brain injury, as undamaged regions can assume functions previously performed by damaged areas. While the mechanisms underlying plasticity are complex, involving molecular cascades and cellular changes, its implications are profound: they suggest that cognitive training and rehabilitation can harness this inherent flexibility to enhance mental function and offset age-related decline.

C. Las lesiones cerebrales eliminan permanentemente todas las funciones asociadas.
D. Los circuitos neuronales se vuelven más rígidos después de la infancia.
✅ 正确答案
Cognitive training can leverage brain adaptability to improve function.
IELTS Reading Tips
Skim the questions first, underline keywords, then locate in the passage
Watch for paraphrasing; correct answers are often reworded
Be wary of absolute statements (all, always, never) — usually wrong
Pay attention to content after transition words (however, but, yet)
