The concept of neuroplasticity, once a controversial hypothesis, has now become a cornerstone of modern neuroscience. Historically, the adult brain was considered a structurally static organ, with neural circuits fixed after a critical period in childhood. However, research over the past two decades has demonstrated that the brain retains a remarkable capacity for reorganization throughout life. This plasticity manifests in various forms, including synaptic strengthening, the formation of new neural connections, and even the generation of new neurons in specific regions such as the hippocampus. Such adaptations are not merely reactive but are also influenced by behavioral experiences, environmental enrichment, and learning. Consequently, neuroplasticity has profound implications for rehabilitation after brain injury, as well as for understanding the mechanisms underlying cognitive decline in aging. Nevertheless, the extent and limits of this plasticity remain subjects of active investigation, with researchers cautioning against overgeneralizing findings from animal models to human contexts.

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)
