The concept of neuroplasticity has revolutionized our understanding of the human brain. Traditionally, scientists believed that the brain's structure was fixed after a critical period in childhood. However, recent research demonstrates that the brain remains capable of reorganizing itself throughout life, forming new neural connections in response to learning, experience, or injury. This adaptability is not uniform across all regions; the hippocampus, for instance, exhibits significant plasticity in adulthood, facilitating memory formation. Conversely, certain sensory cortices show limited plasticity after maturation. Such findings have profound implications for rehabilitation, suggesting that targeted therapies could harness plasticity to restore functions lost due to stroke or trauma. Yet, the mechanisms underlying plasticity are complex, involving molecular cascades and synaptic strengthening, which are not yet fully understood.

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)
Manage time: about 20 minutes per passage; skip difficult questions first
