The concept of 'neuroplasticity' has revolutionized our understanding of the human brain. Contrary to the long-held belief that the adult brain is structurally fixed, research now shows that it remains highly adaptable throughout life. This adaptability is driven by synaptic strengthening and the formation of new neural pathways in response to learning, experience, or injury. For instance, individuals who lose their sight often exhibit enhanced auditory or tactile processing, as the brain reallocates cortical resources. However, plasticity is not inherently beneficial; maladaptive plasticity can lead to chronic pain or phantom limb sensations. Understanding the mechanisms that govern this balance is crucial for developing therapeutic interventions for neurological disorders, yet many questions remain unanswered, particularly regarding the limits of plasticity in aging brains.

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
