The concept of neuroplasticity has revolutionized our understanding of the brain's capacity for change. Historically, it was believed that the adult brain was structurally fixed after a critical period in childhood. However, recent research demonstrates that synaptic connections can be strengthened or weakened throughout life in response to learning and experience. This plasticity is particularly evident in individuals who acquire new skills, such as musicians or bilingual speakers, where cortical reorganization occurs. Moreover, neuroplasticity underlies rehabilitation after brain injury, as undamaged regions can assume functions previously performed by damaged areas. Despite these advances, the extent of plasticity diminishes with age, and the mechanisms governing it remain incompletely understood, prompting ongoing investigation into factors that enhance or inhibit neural adaptation.

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)
